to prevent a "man in the middle attack" the communication between server and client should be encoded.

The message payload utilizes HMAC. This prevents replay attacks. Interception of communication to gain information about cards and PINs is a possible thread but limited as network between server and client is a physically separated network.
But it should still be a easy improvement to activate MQTTS in mosquitto using TLS.
