オイスターカード
An Oyster card can have a longer term "season" ticket loaded onto it (either at a ticket office or on line). Such a ticket can start on any day and be valid for a minimum of seven days and a maximum of one year. Unlike an Oyster card, a contactless card can automatically apply a seven-day travel card rate. If the card is regularly used between any Monday to Sunday period, an automatic cap is applied. The seven-day period is fixed at Monday to Sunday, it cannot be "any" seven-day period, unlike a seven-day ticket applied to an Oyster card. There is currently no automatic cap for longer periods.
