RFID - NFC Use Case

NFC Info

Near Field Communication, or NFC, is a short-range, high frequency wireless RFID communication technology. NFC provides secure wireless communication between internet networked smart NFC devices, like NFC mobile phones, and NFC enabled objects or other NFC reception devices such as other mobile phones, payment terminals or identification readers.

 

NFC

  • Operates in the 13.56 MHz frequency band
  • Based on global standards
  • Uses inductive magnetic field coupling to facilitate communication between a reader and the media content on an NFC tag

 

NDEF

NFC Data Exchange Format (NDEF) specifies a common data format for NFC Forum-compliant devices and NFC Forum-compliant tags.

The NFC Forum has mandated four tag types to be operable with NFC devices. This is the backbone of interoperability between different NFC tag providers and NFC device manufacturers to ensure a consistent user experience.

The operation specifications for the NFC Forum Type 1/2/3/4 Tags provide the technical information needed to implement the reader/writer and associated control functionality for the NFC device to interact with the tags. Type 1/2/3/4 Tags are all based on existing contactless products and are commercially available.

 

  • Tag Type 1 Innovision Topaz
  • Tag Type 2 NXP MIFARE Ultralight and MIFARE Ultralight C, NTAG 213
  • Tag Type 3 Sony Felica
  • Tag Type 4 NXP MIFARE DESFire


Supported Tag Types

SMARTRAC is supporting types 1, 2, 3 and 4 and NXP MIFARE Classic 1k.
