NatWest has revealed it is trialing a new payment card with a built-in biometric scanner.
The UK high-street bank will start testing the new card with 200 customers from mid-April to see if the system can streamline the paying process whilst still providing effective security.
The card will allow users to make contactless payments over the current £30 limit without needing to enter a PIN or give a signature - instead a fingerprint scan will authorise the transaction.

The biometric data is stored within the card itself, meaning it should be more secure than if the bank had control - although there's still a potential risk that a duplicated fingerprint could trick it.
The trial, carried out in conjunction with card providers Visa and Mastercard as well as digital security firm Gemalto, will take place over three months, with Natwest's parent company RBS describing it as "the biggest development in card technology in recent years."
