Print & Mobile Phones: QR Codes, NFC Square Off

NFC requires communication between two computer chips—an initiator and a receiver. The receiver chip has data written to it, and it is typically applied to the back of a sticker. The initiator chip in a smart phone, or other device, generates an active NFC field. If your phone is embedded with an NFC chip, all you have to do is wave your phone over an NFC tag or sticker to trigger an event.
