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.
