SmartCard Arduino Library & Example .ino or .pde


I currently have an arduino powered machine that works as expected (user selects action from keypad - each button is one action) but anyone can access the the machine and enable all options. I want to integrate a Smart Card Interface so I can limit the usage.

For this project, time is like a currency. Each approved user will be given a time balance each month. Each user may use the available time on the arduino freely through the authentication of the SmartCard.

Here's what I need:

- Library (doc.h) and Example ([url removed, login to view] or [url removed, login to view])

The program should do:

- Check card ID is VALID

- Ask for user password -> Validate -> block if 3 wrong attempts

- Display available balance (time) -> sort of a currency

- Prompt for user action

- If enough balance, execute runtime, substract balance from card and print message.

- if not, display "insufficient time balance"

- I will also need to extract from card USERS DATA to log (I already have this code)

Dibujo1 is a flow diagram of what I would expect from the software.

SmartCard_Schem is how I have connected the Socket to the Arduino.

50626-8position contains the specs on the Socket

128440306-40 is the picture of the socket

SLE4442 is the specs of the SmartCards I want to use
