Another open hardware mod experiment: RFID-tag/Reader board for the Freerunner, Nanonote (?) and Beagleboard

[Denis Shulyaka]

Hi Nikolaus,

Great news!

Here in Moscow, some of the tickets to public transport are basically
RFID tags. Will I be able to "copy" them and use my Free Runner for it
with this hardware?

Best regards,
Denis Shulyaka.
