How to Protect Your Business from QR Code Scams

QR codes have become a convenient part of everyday business across Asia. From restaurant payments and digital menus to invoices and marketing campaigns, they allow customers and employees to access information without typing a web address.

However, that convenience also creates opportunities for fraud. Criminals can replace legitimate payment codes, direct employees to fraudulent login pages or use QR codes to disguise phishing links. Businesses need simple procedures to identify suspicious codes, protect customer payments and respond quickly when something goes wrong.

How QR Code Scams Work

QR code phishing, sometimes called quishing, involves using a QR code to direct someone to a fraudulent website or another malicious destination. Unlike an ordinary website link, a QR code conceals its destination until someone scans it.

A common example involves placing a fraudulent QR code sticker over a legitimate payment code. Customers believe they are paying a business, but the replacement code directs them to a different payment recipient. In other cases, the code opens a website designed to imitate a banking service, company login page or payment platform.

Businesses can also encounter malicious QR codes in unexpected emails, invoices and messages. An employee might receive what appears to be a routine request to scan a code to confirm their account or access a document. The destination may ask for login credentials, payment information or the installation of an unfamiliar application.

Where Businesses Are Most Exposed

Restaurants, retailers and other businesses displaying payment codes in public places face the risk of physical tampering. Offices and companies operating online have a different exposure, particularly when employees scan QR codes in emails, supplier invoices or messages that appear to come from familiar organisations.

Minimum Safeguards for Staff and Customers

Protecting a business from QR code scams does not require complicated technology. A few consistent checks can reduce the risk of fraudulent payments and compromised accounts.

• Inspect public QR codes regularly. Check payment stands, menus, posters and other displays for unfamiliar stickers or signs of tampering. Replace any code that cannot be verified.
• Check the destination before opening a link. Staff should preview website addresses after scanning QR codes and watch for misspellings, unfamiliar domains and unexpected redirects.
• Verify payment recipients. Customers using QR payments should check the recipient’s name before authorising a transaction. Businesses should reconcile payments against their actual transaction records.
• Be cautious with unexpected messages. Employees should not scan QR codes in unsolicited emails or messages that ask them to urgently verify an account, reset a password or approve a payment.
• Control official QR codes. Keep an inventory of the codes used by the business, their intended destinations and the employees responsible for maintaining them.

Businesses accepting DuitNow QR payments in Malaysia should remind customers to verify the merchant’s name in their banking or e-wallet application. Cashiers should also check the merchant’s transaction records rather than relying solely on payment screenshots supplied by customers.

For QR codes leading to websites, use official business domains wherever possible. Avoid changing destinations unexpectedly, particularly when customers use the codes to access payment pages or submit personal information.

These precautions work best alongside basic account security. Enable multifactor authentication for important business accounts, keep devices updated and ensure employees know how to report suspicious messages. Our basic cyber hygiene guide for small teams covers the broader controls that support these measures.

What to Do If Someone Scans a Suspicious QR Code

Scanning a fraudulent QR code does not automatically mean a device or account has been compromised. The appropriate response depends on whether the person opened a website, entered sensitive information, installed software or authorised a payment.

If a business discovers that one of its public QR codes has been replaced, remove the fraudulent code immediately. Preserve photographs of the display and record when the problem was discovered. Check recent transactions and inform potentially affected customers when appropriate.

Employees who have entered passwords into suspicious websites should change those passwords through the legitimate service, review account activity and report the incident to their IT administrator. If malicious software may have been installed, disconnect the affected device from business systems and arrange a security assessment.

When a QR code scam results in financial loss in Malaysia, contact the relevant bank immediately. Victims can also call the National Scam Response Centre on 997, which operates around the clock. Report suspected financial scams as quickly as possible, preferably within 24 hours, and lodge a police report.

Make QR Code Checks Part of Daily Operations

Assign responsibility for checking physical payment displays, approving new QR codes and verifying their destinations. Include these tasks in existing opening procedures, marketing approvals or security reviews so that employees can identify unusual changes before they affect customers.

FAQ

These are common questions businesses face when reviewing QR code security.

Can Scanning a QR Code Hack Your Phone?

Scanning a QR code does not normally compromise an updated smartphone by itself. The greater risk is opening a malicious website, entering sensitive information or installing harmful software after scanning. Employees should keep their devices updated and avoid downloading unfamiliar applications from QR code links.

How Can Businesses Tell Whether a QR Code Is Safe?

Businesses should verify where a QR code leads, confirm that its destination belongs to the intended organisation and inspect public displays for signs of tampering. Payment recipients should be checked within the banking application before a transaction is authorised. No single visual check guarantees safety, so businesses should combine these precautions with staff training and clear incident reporting procedures.
