K Ring lets you access the Transport for London network, using it in exactly the same way as you would to make a payment, but making the Transmission Ready gesture over the yellow Oyster reader instead of a card terminal.
To use K Ring on a bus, or at the Tube barrier, make the Transmission Ready gesture (by closing your hand into a fist) directly over the Oyster reader.
Make sure K Ring is within 4cm of the face of the Oyster reader, and positioned directly over the centre of the yellow icon.
Move your hand closer to the reader and hold it until you see a green light, hear a beep and/or see the Tube barrier open.
You can use K Ring to pay as you go on bus, Tube, trams, DLR, London Overground, TfL Rail, Emirates Air Line, Thames Clipper River Bus and most National Rail services in London.
If you use K Ring on London’s public transport network, you’ll benefit not just from a daily cap, but also from a Monday to Sunday weekly cap, which means that it will never cost you more than a daily or weekly travelcard.
However, it’s important to note that the cap runs Monday to Sunday, so if you were going to make many journeys in London over a seven day period that started on a day other than Monday, a weekly Oyster travelcard could be slightly cheaper... but much less convenient!
