Printed QR codes are cheap and useful, but they’re still a multi-step action.
NFC usually converts better because it reduces steps and feels smoother. That’s why the nfc google review card category has exploded — customers tap without thinking.
The best real-world approach is not choosing one. It’s combining both. Many businesses place a google review stand that includes NFC + QR so every customer has a preferred method.
QR is the backup. NFC is the shortcut.
In restaurants, this combo performs extremely well, which is why review cards for restaurants often ship with both technologies now.
