A payment card featuring a fingerprint sensor has been unveiled by credit card provider Mastercard.The rollout follows two successful trials in South Africa, according to BBC. 

The technology works in the same way as it does with mobile phone payments: users must have their finger over the sensor when making a purchase.

Security experts have said that while using fingerprints is not foolproof, it is a "sensible" use of biometric technology.

Mastercard's chief of safety and security, Ajay Bhalla, said that the fingerprint technology would help "to deliver additional convenience and security. It is not something that can be taken or replicated."

However, fingerprint sensors can be compromised.
