NFC NTAG203 Transpoder

Near Field Communication (NFC) technology makes life easier and more convenient for consumers around the world by making it simpler to make transactions, exchange digital content, and connect electronic devices with a touch.

NXP Semiconductors has developed NTAG203 ?NFC Forum Type 2 Tag compliant IC ?to be used with NFC enabled devices according to NFC Forum technical specifications, according to NFC Forum recommendations or Proximity Coupling Devices (PCD), according to ISO/IEC 14443A (see Ref. 2). The communication layer (RF Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. Communication to NTAG can be established only when the IC is connected to a coil. Form and specification of the coil is out of scope of this document. When the NTAG is positioned in the RF field, the high speed RF communication interface allows the transmission of the data with a baud rate of 106 kbit/s.

The NTAG203 is primarily designed for NFC Forum Type 2 Tag applications (i.e. Smart Advertisement, connection handover, Bluetooth simple pairing, WiFi Protected set-up, call request, SMS, goods and device authentication and others).

Typical Applications

NFC card is a typical type of RFID cards, which is widely used in most of prepaid occasions, like retails, bars, hotels and enterprise. A standards-based connectivity technology, NFC harmonizes today抯 diverse contactless technologies, enabling current and future solutions in areas such as:

Access control
Cashless payment
Information collection and exchange
Loyalty and coupons
Car parking
