Send Checksum Command [$c9]
The Send Checksum command is used to authenticate data sent to the PICC in the Authentication Communication
Security mode or the Encryption Communication Security mode.
When a Write User Zone command is sent in Authentication Communication mode or Encryption Communication mode
the data received by the PICC is saved in a buffer until a cryptographic Checksum is received. The host uses the Send
Checksum command to transmit the Checksum it has computed. If the checksum is valid the PICC writes the data; if
the checksum is incorrect the data is discarded and the cryptographic engine is reset.
