RFID technology is increasing its popularity and the payment method is spreading all around us.
There is a popular trend in the UK, that involves hacking into the transit system’s Oyster card and making it an access device that is wearable.
The method of removing the chip from the Oyster card has been documented several times online, showing people making it a fashion accessory.
One great example is the Oyster Ring, created by Dhani Sutanto.
The Ring contains antenna and the RFID chip that can be used to pay on the London Underground.
However, the London authorities prohibit damaging the Oyster card, but that could not stop the trend.
