QR codes are everywhere now. We scan them at restaurants, parking meters, shops, offices, events, delivery notices, product packaging, and even emails. They are fast, simple, and convenient. But that convenience has also created a new opportunity for scammers.
This is where quishing comes in.
Quishing means QR code phishing. It is a scam where criminals use fake or malicious QR codes to trick people into opening harmful websites, entering personal details, making fake payments, or downloading malware.
The dangerous part is that a QR code does not show you the full link before you scan it. You only see a square pattern. That makes it easier for scammers to hide fake links behind something that looks normal.
In 2026, quishing is becoming a serious online safety issue because QR codes are now part of daily life. People scan them quickly without thinking, especially when they seem to come from a trusted place like a bank, delivery company, restaurant, parking machine, or workplace.
If you care about online safety, this is one scam you should understand.
Quick Answer: What Is Quishing?
Quishing is a phishing attack that uses QR codes instead of normal links. A scammer creates a fake QR code that sends you to a malicious website. That website may steal your login details, payment information, personal data, or trick you into downloading malware.
The safest rule is simple:
Do not scan a QR code unless you trust where it came from and check the link before entering any information.
Why Quishing Is Rising in 2026
Quishing is growing because QR codes feel normal. Most people no longer think twice before scanning one. That is exactly what scammers want.
There are a few reasons QR code phishing scams are becoming more common.
First, QR codes hide the final destination. With a normal website link, you may notice spelling mistakes, strange domains, or suspicious words. With a QR code, the actual link is hidden until you scan it.
Second, many people scan QR codes on phones. Mobile screens are smaller, so fake websites can be harder to inspect. A phishing page can look convincing enough for someone to enter login details or card information.
Third, QR codes can appear both online and offline. Scammers can place them inside emails, PDFs, posters, parking signs, restaurant tables, product labels, or unexpected packages.
Fourth, QR codes may bypass some traditional email checks. A security filter may catch a suspicious link in text, but a QR code inside an image or PDF can be harder to detect.
That is why quishing is not just another internet buzzword. It is a practical scam that uses a normal habit against users.
According to Microsoft’s Q1 2026 email threat report, QR code phishing was one of the biggest email-threat shifts of the quarter. Microsoft reported that QR code phishing attacks increased from 7.6 million in January to 18.7 million in March, a 146% rise over the quarter. This shows why quishing is no longer a small or rare scam; it is becoming a serious cybersecurity problem for everyday users and businesses.

How Quishing Works
Most quishing scams follow a simple pattern.
A scammer creates a QR code that points to a fake or harmful website. The Federal Trade Commission warns that scammers can hide harmful links inside QR codes and send users to spoofed websites that look real. If someone logs in on that fake page, scammers may steal the information entered there. Then they place that QR code somewhere people are likely to scan it.
For example, the QR code may appear in:
- an email pretending to be from your bank,
- a fake delivery message,
- a parking meter sticker,
- a restaurant table card,
- a poster advertising a discount,
- a fake invoice,
- a PDF attachment,
- or an unexpected package.
When you scan the code, it may open a page that looks real. It may ask you to log in, pay a small fee, verify your account, claim a reward, track a package, or update your payment details.
If you enter your information, the scammer may steal it.
In some cases, the QR code may lead to a malware download. This can put your phone, accounts, or personal files at risk.
Common Places Where Fake QR Codes Appear
Quishing can happen in both digital and physical places. That is what makes it different from many older phishing scams.
1. Emails and PDF Attachments
A scammer may send an email that includes a QR code and tells you to scan it for “account verification,” “invoice payment,” “security update,” or “document access.”
This is risky because the QR code may send you to a fake login page.
2. Parking Meters and Public Signs
Fake QR code stickers can be placed over real ones on parking meters or public payment signs. A driver may scan the code and pay through a fake website.
This kind of scam works because people are usually in a hurry when paying for parking.
3. Restaurant Menus
Many restaurants use QR codes for menus. A scammer could place a fake code on a table, flyer, or printed card. The fake code may lead to a malicious page or fake payment screen.
4. Delivery Notices
A fake QR code may claim that you need to reschedule a parcel, pay a customs fee, or confirm your delivery address.
This works because people often act quickly when they think a delivery is waiting.
5. Unexpected Packages
Some scams involve packages sent to people with a QR code inside. The code may ask the recipient to scan it to identify the sender, claim a reward, or confirm delivery details.
This can lead to a phishing website or malware.
6. Posters and Public Promotions
A QR code on a poster may promise a discount, free gift, event ticket, or prize. The offer may look harmless, but the link could collect personal information.
7. Fake Business Cards or Flyers
Scammers may use printed flyers or cards that look professional. A QR code may claim to open a product page, appointment form, or payment portal.
Real-Life Quishing Example
Imagine you park your car and see a QR code on the parking meter. It says:
“Scan here to pay for parking.”
You scan it. The website looks normal. It asks for your card details, phone number, and vehicle registration.
But the QR code was actually a fake sticker placed over the real one. The website was not connected to the parking company. You just gave your payment details to a scammer.
This is why quishing works so well. It does not always look suspicious. Sometimes it appears in a place where a QR code feels completely normal.
How to Spot a Fake QR Code
You cannot always tell whether a QR code is fake just by looking at the square pattern. But you can look for warning signs around it.
1. Check for Stickers or Tampering
If a QR code looks like a sticker placed over another code, do not scan it. This is common on parking signs, payment machines, posters, and public notices.
Look for signs such as:
- peeling corners,
- mismatched colors,
- crooked placement,
- extra stickers,
- damaged print,
- or a code placed over another label.
If the QR code looks physically altered, avoid it.
The FBI also advises users not to scan randomly found QR codes and to avoid QR codes that appear tampered with. It also warns people to be suspicious if a scanned QR code asks for passwords or login information.
2. Be Careful With Urgent Messages
Scammers often use pressure. They may say:
- “Your account will be locked.”
- “Pay now to avoid a fine.”
- “Your package will be returned.”
- “Scan within 10 minutes.”
- “Claim your reward today.”
Urgency is a common phishing tactic. If a QR code message pushes you to act fast, slow down.
3. Preview the Link Before Opening
Most phone cameras show a preview of the link before opening it. Do not tap automatically.
Check the website address first. Be suspicious if:
- the domain looks misspelled,
- the link is very long and messy,
- the domain does not match the real company,
- the site uses strange words or numbers,
- or the link uses a URL shortener with no clear destination.
For example, if a QR code claims to be from your bank but the website address does not match the bank’s official domain, do not continue.
4. Avoid Logging In After Scanning a Random Code
A QR code should not normally ask for sensitive login details unless you are completely sure it is official.
Be extra careful if the page asks for:
- banking login,
- email password,
- one-time password,
- credit card number,
- national ID details,
- phone verification code,
- or recovery codes.
If you are unsure, close the page and visit the official website manually.
5. Watch for Fake Payment Pages
Fake QR codes often lead to payment pages. These may look professional, but the money may go to a scammer.
Before paying, check:
- the website address,
- the company name,
- spelling and design quality,
- payment amount,
- and whether the page matches the official service.
When possible, use the official app instead of scanning a public QR code.
6. Be Suspicious of QR Codes From Unknown Senders
If a QR code arrives through a random email, text message, social media DM, or package, treat it with caution.
A legitimate company usually gives you another way to access the same information, such as an official website or app.
7. Do Not Download Apps From Random QR Codes
Some malicious QR codes may push you to install an app or file. This is risky.
Only download apps from official app stores or official company websites. Do not install unknown APK files or profiles because a QR code told you to.
What to Do Before Scanning Any QR Code
Here is a simple checklist you can use before scanning.
| Question | Safer Action |
|---|---|
| Do I trust where this QR code came from? | Scan only if the source is clear and reliable. |
| Does the QR code look like a sticker? | Avoid it if it seems pasted over another code. |
| Is the message urgent or threatening? | Slow down and verify manually. |
| Does the link preview look official? | Check the domain before opening. |
| Is it asking for login or payment details? | Visit the official app or website instead. |
| Is it from an unknown email or package? | Do not scan unless you can verify it. |
This small pause can protect your accounts, money, and personal data.
Quishing vs Phishing vs Smishing
Quishing is part of the larger phishing family, but it uses QR codes as the trap.
| Attack Type | Meaning | Example |
| Phishing | Fake emails or websites that steal information | A fake bank email asks you to log in |
| Smishing | Phishing through SMS/text messages | A fake delivery text asks you to pay a fee |
| Quishing | Phishing through QR codes | A fake QR code opens a malicious payment page |
| Vishing | Phishing through phone calls | A scammer calls pretending to be your bank |
The goal is usually the same: steal information, money, or account access. The method is different.
What Happens If You Scan a Fake QR Code?
Scanning a QR code does not always mean you are immediately hacked. The risk usually depends on what happens after scanning.
You are at higher risk if you:
- entered your login details,
- typed card information,
- downloaded a file,
- installed an app,
- shared a one-time password,
- allowed permissions,
- or connected your account to a suspicious service.
If you only scanned the code and closed the page without entering anything, your risk may be lower. But you should still be careful and monitor your device.
What to Do If You Scanned a Fake QR Code
If you think you scanned a malicious QR code, act quickly.
1. Close the Page Immediately
Do not enter more information. Close the browser tab or app.
2. Do Not Download Anything
If the page asks you to install an app, update software, or download a file, do not continue.
3. Change Your Password
If you entered login details, change your password immediately from the official website or app.
Use a strong and unique password. Do not reuse the same password across accounts.
4. Enable Two-Factor Authentication
Turn on two-factor authentication where possible. This adds another layer of protection if your password was stolen.
5. Contact Your Bank
If you entered payment details, contact your bank or card provider quickly. Ask them to block suspicious activity or replace the card if needed.
6. Check Your Device
Run a security scan if you downloaded anything. Also check for unknown apps, profiles, or permissions.
7. Report the QR Code
If the fake QR code was in a public place, report it to the business, building owner, parking company, restaurant, or local authority.
If it came through email, report it as phishing.
How Businesses Can Protect Customers From Quishing
Quishing does not only hurt individuals. It can also damage business trust.
If scammers place fake QR codes over a company’s real codes, customers may blame the business. That is why companies should take QR code safety seriously.
1. Use Branded Landing Pages
A QR code should lead to a clear, official, branded page. Customers should immediately recognize the business.
Avoid strange third-party domains when possible.
2. Add Short Instructions Near the Code
For example:
“This QR code should open technopublication.com only. Do not enter payment details on any other website.”
This helps users know what to expect.
3. Check Physical QR Codes Regularly
Businesses should inspect QR codes placed on:
- tables,
- posters,
- product labels,
- payment counters,
- parking signs,
- office entrances,
- and public displays.
If a sticker has been placed over a code, remove it immediately.
4. Use Tamper-Resistant Labels
For public QR codes, businesses can use stronger labels, secure placement, or printed signs that are harder to cover.
5. Avoid Asking for Sensitive Details Through QR Codes
A QR code should not randomly ask customers for unnecessary personal information.
Only collect what is needed.
6. Train Staff
Employees should know how to identify fake QR codes and what to do if a customer reports one.
7. Give Customers an Alternative
Not everyone wants to scan a QR code. Businesses should also provide a written website address, official app name, or physical payment option.
How to Protect Yourself From QR Code Scams
Here are simple online safety habits that work.
Use Official Apps When Possible
For banking, payments, parking, deliveries, and shopping, use official apps instead of scanning random QR codes.
Type the Website Manually
If the QR code claims to come from your bank or delivery company, go to the official website yourself instead of trusting the scanned link.
Keep Your Phone Updated
Software updates fix security weaknesses. Keep your phone, browser, and apps updated.
Use Secure Wi-Fi
Avoid entering sensitive information on public Wi-Fi. If you are using Wi-Fi at home, make sure it is protected properly. You can read our guide on How to Secure Your Wi-Fi Network: A Step-by-Step Guide for more safety tips.
Be Careful With AI-Generated Scams
Scammers are also using newer tools to create more convincing messages, fake websites, and social engineering attacks. If you want to understand this wider threat, read our article on AI-Powered Cyberattacks – How to Recognize and Deal with Them.
Protect Your Personal Information
Quishing is dangerous because it often targets private data. Be careful with your name, email, phone number, address, passwords, card details, and verification codes.

Are QR Codes Unsafe?
No, QR codes are not automatically unsafe.
A QR code is only a tool. It can lead to a safe website, a menu, a payment page, a document, or an app download. The danger comes from where the QR code sends you.
Think of a QR code like a normal web link. A trusted link can be useful. A fake link can be harmful.
The problem is that QR codes make the link harder to inspect before opening. That is why users need to be more careful.
The Biggest Mistake People Make With QR Codes
The biggest mistake is trusting a QR code just because it appears in a normal place.
A QR code on a restaurant table, parking meter, office wall, or package can still be fake. Scammers rely on the fact that people trust the environment around the code.
A better habit is this:
Trust the source, not the square.
Before scanning, ask yourself:
- Who placed this QR code here?
- Does it look original or tampered with?
- What website does it open?
- Is it asking for information it should not need?
- Can I use the official app or website instead?
That one pause can stop many scams.
Simple Quishing Safety Rule
Use this three-step rule:
Stop
Do not scan automatically. Take one second to check the source.
Check
Look at the QR code placement, message, and link preview.
Verify
If money, login details, or personal data are involved, use the official website or app instead.
This rule is easy to remember and works for most QR code scams.
FAQs About Quishing
Quishing is QR code phishing. It is when scammers use fake QR codes to send people to malicious websites that steal information, money, or account access.
A scammer creates a QR code that leads to a fake website. When someone scans it, the page may ask for login details, payment information, or personal data.
Scanning alone does not always hack your phone. The risk increases if you open a harmful link, enter sensitive information, download a file, or install an unknown app.
Look for signs of tampering, strange placement, urgent wording, suspicious link previews, misspelled domains, and requests for sensitive information.
Many restaurant QR codes are safe, but you should still check that the code does not look like a sticker placed over another code. Avoid entering personal or payment details unless you trust the page.
Contact your bank immediately, block or replace the card if needed, check for suspicious transactions, and change any related account passwords.
No. QR codes are useful, but businesses should make them safer by using official domains, checking physical codes, adding clear instructions, and avoiding unnecessary data collection.
The best way is to verify the source before scanning, preview the link, avoid entering sensitive data after scanning random codes, and use official apps or websites for important tasks.
Final Thoughts
Quishing is dangerous because it turns a normal everyday action into a possible scam. Most people scan QR codes quickly because they seem harmless. That is exactly why scammers use them.
The good news is that you do not need to panic or stop using QR codes completely. You only need better habits.
Check the source. Preview the link. Avoid urgent messages. Do not enter sensitive information on suspicious pages. Use official apps when money or passwords are involved.
QR codes are convenient, but convenience should not replace caution.
