Insider Tips On The London Oyster Card
The Oyster smart card system has significantly changed the way London’s “tube” operates.
An Oyster card lets you make use of the majority of the London transport system (even though some places choose to stay outside the scheme).
It provides a big discount on standard fares and also helps save you time in queueing to buy tickets.
The system automatically saves you money by calculating the lowest fare at the end of each day based on your exact travel that day.
If you travel more than you expected to initially, it only charges you the lowest fare instead of pricey singles and returns.
