16.7 Initiate Application Processing

This informs the card that a new transaction will begin.

The terminal executes GET PROCESSING OPTIONS with a parame-

ter, that are OPTIONAL optional terminal-resident data objects (speciﬁed

by a PDOL object provided by the card). We will assume here that this

option is not used (most of time it is the case) and therefore there will be

no terminal-resident data objects.

We send the following command:

GET PROCESSING OPTIONS

CLA INS P1 P2 Lc DataIn Le

80 A8 00 00 02 8300 00

where Le = 0 is assumed.
