Ideally, session is encrypted and authenticated at all levels
- User should know they are interacting with a legitimate terminal
- Token should know that it is talking to a legitimate reader
- Reader should not leak any secrets during transaction
- Secrets should not be subject to interception between reader and server/panel
  - Physically secure wiring/network
  - Secure/encrypted protocols
Messages should be not be able to vulnerable to session replay
- Time stamping/serializing of messages
Messages should not be subject to intentional or accidental alteration in transit
- Message CRC and cryptographic signing/MAC protocol
