Grid card for two-factor authentication

I’ve been asked to develop a demonstration of two-factor authentication using a grid card (aka. bingo card) so I started researching a little bit on this and the only thing I could find is the following fork for the phpSec project, https://github.com/multiwebinc/phpSec, which implements it.

So I downloaded the source code and assembled a very simple demonstration page hosted at http://gridcard.demo.blobfish.pe.

Some screenshots follows:
