3.2.3.3 Mandatory Commands

The data packet from the host to the reader is known as the request and the reply from the
reader to the host as the response. The host is always the primary station and initiates all
communication sequences. These consist of request/response pairs where the host waits for a
response before continuing. All ISO/IEC 15693-3 command request packets are contained
within the standard reader command request packet format. In all cases, reader command 60
is used to pass through ISO 15693 Part 3 commands to the reader.
