Fraud alert over new tap and pay bank cards: Thieves use scanners to steal account details – even when contactless card is in your wallet

Tests show that thieves armed with scanners can capture the numbers and expiry dates on the cards and use them for online purchases.

Touted as a boon for shoppers making small transactions, the ‘tap and pay’ cards do not need a PIN number.

Instead they have a tiny antenna that links with a till terminal through near-field communication, or NFC.

But a scanner held nearby can pick up this NFC data, according to the consumer group Which?.
