A passkey ring

Former graphic designer Benjamin Parton, a Royal College of Art Student, has designed a wearable Oyster card (the electronic travel card used to pay for London transport). It is a chunky blue plastic ring which he’s named the Oi.

The ring works much like the present credit-card sized plastic Oyster cards by holding week or month-long travel cards and money, which allows the wearer through the gates at tube stations or onto buses by pressing the ring on the radio frequency discs which read the cards, permitting travel.

Parton said: “I thought the card had become synonymous with London and was even a little bit loved for its designs but it’s remained unchanged for eight years and as an object I thought it lacklustre and boring. I wondered if it would be made more fun.”

He went through 30 different designs for the radio frequency coil that is contained inside the ring, testing them late at night.

Parton has filed a patent for the design and expects to sell them for £6, though he is still in need of a manufacturer.
