LONDON: Mastercard has launched Tap & Go, a 'touch and pay' system in the UK. It is specifically designed for small, swift purchases below £10 ($20; €14).

Branded PayPass, the new card enables consumers to pay for goods simply by tapping their plastic against a special cardreader - rather than having to use a PIN number or hunting for cash.

The scheme debuts in London, with a national rollout expected next year. Despite some critics' fears that the card is vulnerable to to fraud and theft, rival Barclaycard is to unveil its own version imminently.
