QR Codes — Your Daily Shortcut
QR codes are the square black-and-white patterns you see at restaurants, shops, clinics, stations, and on printed letters. They are quick links that your phone camera can read in seconds.
How to scan a QR code
On an iPhone:
- Open the Camera app (you do not need a special QR app).
- Point the camera at the QR code — hold steady for 1–2 seconds.
- A notification or yellow box appears — tap it to open the link.
On Android:
- Open the Camera app.
- Point at the QR code — a link should appear automatically.
- If it does not, open Google Lens (tap the coloured circle in the camera) and point at the code.
Most Android phones from 2019 onwards scan QR codes directly in the camera.
Common QR code uses
1. Paying at hawker centres and shops (instant bank transfer/PayLah)
- Open your banking app (your bank) or your bank PayLah!.
- Tap Scan & Pay.
- Scan the QR code on the counter.
- Check the recipient name that appears.
- Enter the amount and tap Confirm.
2. Restaurant and café menus Scan the table QR code to view the menu on your phone — no physical menu needed. Some let you order and pay directly.
3. Health-service portals — appointments and test results Your COVID-19 vaccination certificate has a QR code. Scan it to verify authenticity.
4. official government login — fast login Many government websites show a QR code for official government login login. Open the official government login app, tap Scan QR, and point at the code on the website — you are logged in instantly without typing.
5. Wi-Fi connection Some cafes, libraries, and community centres display a QR code that automatically connects your phone to their Wi-Fi — no password needed.
Staying safe with QR codes
- Before paying: Always check that the name shown in the payment app matches who you are paying.
- Check for tampered stickers: If a QR code sticker looks like it has been placed over another one, ask a staff member before scanning.
- Opened a suspicious link by mistake? Close the browser immediately without entering any information.
- Never enter personal details (national ID, password, OTP) on a page that opened from a QR code unless you are certain of the source.
A QR code is just a shortcut to a website or payment. The same safety rules for websites and payments apply.
