High-Performance Desktop RFID Card Reader/Writer
RCR-3342 is a high-performance desktop RFID card reader/writer , read and write (Classic S50 and S70, Plus X,S), ISO 14443A/ B, ISO 15693, Desfire series card,
with one SAM slot, RS232/USB/TTL interface for optional.
It can be widely applied in the industries of attendance system, access control, public transportation, and any other terminal systems.
. Data packet format
There is three kinds of data packet: packet head, data block, command. When a USB command length is over 64byte, it
will adopt separating packet transmission, the separated command is resealed by new data packet, it is called data block.
It should send packet head at first before sending data block, packet head contains the detailed information of sending
data block.
