Are there any advantages to conserving magstripe playing cards or tokens round?
“No,” says Sue Walnut, product director for clever transportation programs at Vix Know-how, bluntly.
She argues there at the moment are so many various methods of validating a rail ticket – for instance, QR codes offered on telephone screens, tickets printed at residence, pay as you go contactless playing cards – that there’s much less must retain magstripe know-how than ever earlier than.
However magstripe tickets and entry playing cards do slot conveniently into bank card holders in wallets and purses. The brand new paper tickets being trialled by Northern and different rail corporations are bigger. “They’re a bit unwieldy and cumbersome,” says Ms Walnut.
