This example demonstrates simple low-level API usage to perform detection, anti-
collision, activation, authentication and R/W operation on the Type A cards according to
ISO14443 standard.
Application is using low level RF interface HAL implementation in flash. There is
limitation to only one card at the time. Supported TypeA cards are Type1 TOPAZ,
MIFARE Ultralight, MIFARE Classic, MIFARE DESFire cards will pass through activation
and anti-collision and. In the case of MIFARE Classic card also authentication with
default key is demonstrated. In the case of MIFARE DESFire card L4 activation is
demonstrated.
Application trace in case of MIFARE DESFire card is as follows:
Polling Start
Found TypeA
DesFire R/W PASS : =106
DesFire R/W PASS : =212
DesFire R/W PASS : =424
