Partial Selection (FFE1 or DFEE4B)
For some applications, an AID on the card may be longer than an AID configured in the reader.
If partial selection is allowed, the AID will be considered a match if all of the AID configured in
the reader matches the first portion of an AID in the card.

Value
Description
-------x
Partial selection is
allowed
0 = This AID does not participate in partial selection
1 = This AID will participate in partial selection (default)
For M/Chip 3.0, this value should be set to “allowed.”

Historically, Partial Selection has been a separate tag. However, it is an integral part of the
selection process, and may be used in conjunction with combined selection features.

AID Participation in Selection Processes (FFE8 or DFEE53)
In some cases, applications or AIDs may not be able to participate in some of the selection
processes. For example, some cards or applications do not support PPSE. The following table
describes the bits in tag FFE8 that may be used to exclude an AID from selection processes.

“Trial & Error” is sometimes referred to as “List of AIDs.” It is a process by which the reader
will attempt to select an AID by going through its list, hoping for a successful selection.
For M/Chip 3.0, tag FFE8 should be set to 0x00.
