demo: rfid reader + arduino for point of sale solution

i’ve put together this video as a demo of “intuit checkout” – the idea that won the last intuit ideajam contest.

intuit checkout is a low-cost point of sale hardware/software solution that uses an arduino prototyping board and a parallax rfid reader.

all of the item data associated with the unique ids on the rfid’s are stored securely in a quickbase online database.

    Cool stuff! Do you have anything stating what you used such as type of RFID reader? and how you hooked it up to the arduino?

    I’m a little lost, perhaps I am missing it somewhere, but I just cannot seem to find the source (or a link to it) anywhere on the page….
