1. An apparatus comprising:
one or more processors operable to execute stored instructions that, when executed, cause the one or more processors to:
receive a first instance of a message from a contactless card via a near field communication (NFC) reader;
determine that one or more portions of the message were not correctly received via the NFC reader;
send a request to retransmit the message to the contactless card;
receive a second instance of the message from the contactless card via the NFC reader;
combine a portion of the first instance of the message with at least a portion of the second instance of the message; and
determine the message is correctly received via the NFC reader based on a checksum calculation.
