Transport for London have admitted today that tube users with Oyster Cards have been overcharged and that passengers who renewed their Oyster cards online on 1 January but were unable to validate them until the fourth had their transactions cancelled and were forced to pay higher 2005 prices.
Now the LibDems have jumped on the bandwagon and are demanding a public enquiry into the system. A quick look at the website for TranSys (the company behind the Oyster Card system) shows that their press office is right on top of the problem:
"28/07/2004: Oyster card wins public nominated award"
Londonist's favourite Oystercard site is undoubtedly The Oyestercard.co.uk which details the various ways you can disguise your Oyestercard. For example: in a slice of brown bread.
