Giving a new meaning the the term "blood money" British tech authentication company Sthaler is developing a 3D map of the veins in users' fingers to replace cash and card payments.
'Fingopay' would see the unique 3D map of users' finger veins stored in the cloud enabling them to authorise payments with one touch, anywhere they go, according to CNet.com.
Sthaler claims 'Fingopay' is more secure than a fingerprint because each finger vein is unique and the odds of two people having the same vein structure are 3.4 billion to one.
Some services have already introduced fingerprint scanners, voice recognition and Face ID, but so far they have all been proven not be 100 per cent secure.
Elliott Goldenberg, Mastercard's UK head of digital payments, explained: "Authenticating with your voice won't work if you're on a train, or paying through facial recognition is less appealing if you're in a dark room. That's why we don't want to push one particular biometric over another."
Sthaler has now teamed up with Danish debit card group Dankort to allow customers to use 'Fingopay' while out and about shopping.
An infrared scanner reads the vein pattern in their finger and deducts the correct amount of money from an electronic wallet.
The company hopes to export the technology throughout Europe.
