Remote control Pin Sentry

Using a standard SMS board from the internet

 

Some ribbon cable, a few  gates , diodes resistors and some awful code ;)

 I can log into my internet banking, knowing my input device is in a secure location.

If they had made the device a bit smaller, I would be tempted to carry it around with me,

but it is the size of a 1970’s calculator.

The output is decoded directly from the display driver, multiplexed sent to the SMS controller,

which after authentication from my phone sends the code as an sms message.
