NFC vs QR codes for reviews: which works better

How they work

• NFC: the customer holds an unlocked phone a few centimetres from the card and the page opens by itself. No app, no camera.
• QR code: the customer opens the camera, points it at the code and taps the link that appears.

Which phones read them

• iPhone: iPhone XS and XR and newer read NFC automatically with the screen unlocked. iPhone 7 to X read it through a button in Control Centre.
• Android: most phones have NFC; it just has to be switched on in settings. Some very cheap models have none.
• QR: any smartphone with a camera, including those without NFC.

Where each one wins

• NFC is faster: one tap instead of three steps, and it works in low light.
• QR works at a distance: on the door, in the window, on a poster or a receipt.
• Best together: an NFC card that also carries a QR code covers every phone.

Where to place them

• Where the customer already has their phone in hand: at the till, on the table, at reception.
• Not on metal surfaces: metal can block the NFC signal. Very thick phone cases can make reading harder.
• Out of strong sunlight, so the print stays readable.

Safety

QR codes stuck over real ones are a known scam. Check now and then that the code on your card and posters is yours. Recenzio cards always lead to a recenzio.ro address, and you change the destination from the dashboard without changing the card.
