im a kinda newbie want to know what is the hype about track 3 on amex card i got a couple and want to know how to use them if there is something to use them for... it's twelve digits on track 3
encode it exactly same as you encode a normal dumps ,when you put data into software , TR1 data -->Track 1 ETC ....
THEN encode same , now u can read card on ur MSR and see 3 track on magstripe . You not need BIg magstripe , a normal plastic is ok .
Its good have tr3 if you got Pin code ( because u can get balance info & sometimes access to checking & saving ) but rarely POS check the track 3 .
