5.5.2. Transmission Protocol for ICC Cards
Following are the command/response protocols for communication between the
hybrid reader (ICC media) and host. The protocol used by this reader is turbo TLP224. All commands and characters are presented in ‘Hex’. Note: Maximum buffer
size for read is 256 bytes and for write is 255 bytes.
