Whilst the Oyster PAYG rollout to National Rail was long awaited and much welcomed, news that passengers overpaid around £500,000 in January is not entirely surprising. The BBC report blames user ineptitude, with travellers failing to comply with the touch in, touch out mantra. Key is that “when you touch in an entry charge of up to £6.50 will be deducted from your Oyster card. When you touch out, the charge will be adjusted so that you pay the appropriate Oyster single fare.” And if you don’t, you’ve already been charged. There’s an extensive ‘how to’ on the TfL website. Let us know if you’ve been caught out. We’re also interested to know if you’ve fallen foul of the Oyster Extension Permit palava as yet.
