SMS PIN Sentry Reader

November 3, 2007 by Will O'Brien 39 Comments


[Mr G] in London sent in his pin sentry hack. He wasn’t pleased that the device looks like an old calculator, so he rigged up a SMS board to send him his pin on demand. He multiplexed the output of the display driver to the SMS board. When he authenticates from his phone, the board sends a message with the latest code.
