While smart transit cards are easily more convenient than carrying exact change to pay your subway fare, the Oi Wearable Travel Card makes it even simpler still to board the bus. Like London's existing Oyster Card system, the radio frequency chip within contains and transmits information about the balance on your public transit account.

The major difference established by Benjamin Parton's invention is that it does not require you to fumble with your purse, pocket or wallet before and after you pass through the turnstiles. The small silicone band of the Oi Wearable Travel Card can be added to a wristwatch strap as a widget or stretched out and sported as a finger ring so that it can be kept hands-free, yet handy, for regular commuters.
