RFID Labels & Tags: What are NFC Tags?
FC (Near Field Communication) tags are passive, high-frequency (HF) RFID tags that contain a NFC Data Exchange Format (NDEF) compliant data structure as defined by the NFC Forum. NDEF data, like a URL or contact, is understood by any NFC compliant reader device, such as a mobile phone, without requiring an extra API
NFC Tag Uses
NFC tags are often used as a convenient replacement of a QR code, and simply host a URL that is opened when the tag is tapped with an NFC phone.
NFC tags may also host other information such as contacts, images, actions or phone numbers.
Public transport tickets may be NFC tags.
