RFID Ring : Proof of concept and Rapid Prototyping

The previous post RFID : Physical Hacking of the EZlink Card had documented the process of extraction. The following are proof of concept videos testing the RFID readability on a ring.

The ring is tested at an the actual designated top up machine meant for the EZLink cards.
The ring was then tested at the the gantry to see if it also worked at another RFID reader.
Apart from readability tests, the ring was also tested for the ability to have monetary value added to it.
