This paragraph introduces some of the terms used in ISO 7816-3 and EMV recommen-
dations. Please refer to the full recommendations for a complete list of terms.
Terminal is the reader, ICC is the Integrated Circuit Card
Elementary Timing Unit (Bit time)
Character oriented half duplex protocol T=0
Block oriented half duplex protocol T=1
Reset initiated by the Terminal with Vcc power-up. The card will answer with ATR (see
below)
Reset initiated by the Terminal with Vcc already powered-up, and after a prior ATR or
Warm Reset
Deactivation by the Terminal as a result of : unresponsive ICC, or ICC removal.
