8.5 DUKPT Level 4 Data Output Original Format

For the ISO card, both clear and encrypted data are sent. For other cards, only

clear data is sent.

A card swipe returns the following data:

Card data is sent out in the following format:

<STX> = 02h, <ETX> = 03h.

<LenL><LenH> is a two-byte length of <Card Data>.

<CheckLRC> is a one-byte exclusive-OR sum calculated for all <Card Data>.

<CheckSum> is a one-byte sum value calculated for all <Card data>.

<Card Data> format is
