SyncCheckID 7B 1
check for

allow poorly
encoded
cards to be
read
‘2’ (‘0’-2’)
check leading & trailing sync bits.
‘0’ 13 bits.
‘1’ 13 bits but allow if valid through track LRC.
'2' 9 bits ABA; 13 bits IATA; 16 bits JIS.
EncryptOptID 84 1

only
0 encrypt card
type 0; (0-1F)
If bit 0 is set, track 1 will be forced encrypted
and the track 1 mask data won't be output.
If bit 1 is set, track 2 will be forced encrypted
and the track 2 mask data won't be output.
If bit 2 is set, track 3 will be forced encrypted
and the track 3 mask data won't be output.
• These bits setting can be used for
both financial and non-financial
cards. The difference is that the
mask data won't be output when
these bits are set because there is
no rule how to mask the non-
financial card data. It is valid both for
Non – CC and card type 0.
bit 3 encrypt trk3 if card type 0.
bit 4 encrypt trk3 if card type 0 only and allow
trk1, trk 2, trk3 masked data to be sent as
well.
note:1. General ISO card trk3 mask is always
not present, except for command 0x91. In this
command, trk 3 mask is only for 4909 card.
