RFID

As previously stated, RFID cards were another resource we were exposed to during the first workshop. And RFID will be most popularly known as a device used in Oyster cards.

We know the whole purpose of Oyster cards in London and they have proven a very effective tool to travel with since the basic paper travel cards. But it was the technology behind the cards which was brought to our attention. We watched a demonstration video of how the card works, but most interestingly, it can be used with the Arduino boards with the help of an RFID card reader extension.

As you can see from this picture the extension is connected to the Arduino and with the correct coding implemented into the Arduino, the RFID card can be read, which can then be used to either simply collect data or perform another function. RFID tags come in so many different forms and sizes some even small enough to be embedded into human skin.
