NFC (Near Field Communication) and QR codes are both contactless technologies for sharing data. NFC requires physical proximity (~4cm) and a compatible device, while QR codes work at any distance with a camera.
NFC uses radio waves between a tag and a reader device. The user taps their phone on the NFC tag to receive data. QR codes use a visual pattern scanned by a camera. NFC tags cost $0.10-2 each and need physical installation; QR codes are free to generate and can be printed anywhere.
