P2
One of the parameters used in a TPDU. Specific usage depends on
the TPDU being used.
P3
One of the parameters used in a TPDU. It is used to code either Lc
or Le. If both Lc and Le are zero, P3 is zero.
PIN
Personal Identification Number. Many Smart Cards have security
mechanisms which presentation of a PIN to authorize usage of the
card.
Procedure Byte
This byte is part of the card level communications for
Microprocessor Cards using the T=0 protocol. It used to regulate the
flow of data from the card to the reader. The Model 152 handles all
procedure bytes, relieving the host of having to even know that
procedure bytes exist.
RFU
Reserved for Future Use. When sending a command to the reader,
any field documented as RFU should be filled with zeroes.
RS232
An electrical specification of a communications system which used
between parties on a communications line. The Model 152 is RS232
compatible.
SAM
Secure Application Module. Many Smart Card applications require
security to protect against fraud. Many security schemes are
implemented via SAMs which are Smart Cards which make security
algorithms available and supply a secure place to store keys. It is
quite difficult to discover the value of a key stored in a SAM.
SAM Box
This accessory available for connection to the Model 152 allows the
reader access for up to seven additional SAMs. The SAM box may
be stored under the counter or in some other secure location.
Secure Application Module
See SAM.
Serial Cards
See Memory Cards.
Smart Card
Any card with implanted integrated circuitry. The Model 152 is used
to read and write Smart Cards conforming to ISO 7816 standards
for Integrated Circuit Cards with Contacts.
EOT
End Of Transmission. This byte is used in many communications
protocols to signify the end of a transmission. In the ASCII character
set it is defined to have the value 04H.
