Hi guy,
I've a doubt: I read around the Internet that Track2 of Credit Card are made up of 40 character (see here
So I'm asking if they are truly written in the card?
Yes, The start and stop sentinels are written. The circuitry within the reader looks for them. They are usually non printing characters like Chr$(12) or Chr$(13). Some security card readers even use non- standard sentinels just to protect the integrity of the system.
And the LRC are also written on the card?
