Description POS transaction packets transmitted from a POS terminal to a POSPAD are
encapsulated in either synchronous format or asynchronous format.
In synchronous format, a POS transaction packet is made up of a TPDU starting with
60 and an ISO 8583 packet. The POSPAD could not recognize the start and end of
this type of packets. To do that, it must use a control mechanism.
In asynchronous format, a POS transaction packet is a synchronous packet
encapsulated starting with 0x02. The packet includes information such as length of
the packet and checksum.
The same encapsulation format must be adopted on the connected POS terminal and
POSPAD.
