(2) Only valid for Mifare, Desfire and Vicinity cards.
(3) Used not very often. Kept only for backward compatibility purpouses.
7 Data
There are three types of data to be read by the Desktop Reader (or Wall Reader Adaptor):
ROM code or Serial Number This is a factory programmed code particular for each card
TRACKS Emulates the Tracks 1, 2 and 3 of the magnetic stripe cards.
WIEGAND CODE Emulates de Wiegand code of access control cards
7.1 ROM code
The Salto ROM code is a 7 byte code different for each card. Normally each byte is expressed as a
double hexadecimal character so the total ROM code will be 14 ASCII characters (called ROM14). If the
bytes are represented by their 8 bits the total 56 bits representation is called ROM56.

7.1.1 ROM code and Serial Number
The relation between the ROM code and the card Serial Number depends on the technology of the card.
