	I recomend you don't to use "card readers"... that technology could be expensive and dificult to mantain. The system you're building could have an easy solution for the user card. Why don't prepare a data base with many passwords? When a user type it's pasword over a keypad the system will know how many money the cards has... evaluate if you really need the card reader. Best regards
