NDEF NFC Card Ntag203 ISO14443A 13.56MHz card

NXP Mifare card 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 . The communication layer (RF Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. 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).
Features and benefits
RF Interface (ISO/IEC 14443A)
> Contactless transmission of data and supply energy (no battery needed)
> Operating distance: up to 100 mm (depending on field strength and antenna geometry)
> Operating frequency: 13.56 MHz
> Fast data transfer: 106 kbit/s
> High data integrity: 16-bit CRC, parity, bit coding, bit counting
> True anticollision
>7 byte serial number (cascade level 2 according to ISO/IEC 14443-3)
>168 bytes of total memory, divided in 42 pages (4 bytes each)
> 144 bytes of user r/w memory area, divided in 36 pages (4 bytes each)
> Field programmable read-only locking function per page for first 64 bytes
> Field programmable read-only locking function per block
> 32-bit user definable One-Time Programmable (OTP) area
> 16-bit counter
> Data retention of 5 years
> Write endurance 10000 cycles
> Anti-cloning support by unique 7-byte serial number for each device
> 32-bit user programmable OTP area
> Field programmable read-only locking function per page for first 512 bits
> Read-only locking per block for rest of memory
Cascaded UID
The anticollision function is based on an IC individual serial number called Unique IDentifier. The UID of the NTAG203 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3.
An intelligent anticollision function according to ISO/IEC 14443 allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field.

Proximity cards id card are extensively utilized by companies to keep treatments for the physical access of the employees. All the employees is allotted a proximity card, they will must show as you're watching card reader. The credit card reader receives the ID through the card and it transmits exactly the same for the central computer. It is merely it is decided whether the person are certain to get entry in to the restricted area or not. Proximity cards can also known as prox cards. They basically make reference to contact less integrated circuit devices, that happen to be mainly utilized for security reasons. Proximity cards can be stated to become a kind of smart cards.
