The days of being caught short at the till after forgetting your wallet could soon become a thing of the past.
The brains behind this biometric terminal, which allows shoppers to pay for their wares using just their fingerprints, claim their machine is attracting interest from retailers across the globe.
Paytouch users link their credit card details to their fingerprints, letting them spend to their hearts' content without the need for PIN numbers, signatures, or even the card itself.

The fingerprint recognition system provides 'faultless identity verification', says the Spanish start-up.
According to Paytouch its terminals are equipped with capacitive biometric sensors to prevent the use of fake fingers.

WHAT IS BIOMETRICS?
Biometrics refers to methods used to identify humans based upon one or more intrinsic physical or behavioural traits.
In information technology it is used as a form of identity access management and access control.
Humans' biometric characteristics can be divided into two main categories:
Physiological, such as fingerprints, DNA, face recognition, palm geometry or iris recognition
Behavioural, such as rhythm, gait and voice
In the short-term the firm is hoping to launch Paytouch terminals in supermarkets and petrol stations across Spain, before branching out into other European countries and the U.S.
Shoppers could also see the technology cropping up on payment terminals that require a credit card swipe or PIN code, as the firm has been fielding requests from customers who want to see the biometric aspect integrated into their existing machines.
CEO Javier Paso told Engadget.com: 'We're hoping to have more deals in place by the end of the year.'
But he added that there was likely to be a pause in activity as Paytouch prepares for large scale expansion.
'...We need additional funding for additional infrastructure so we can assure excellent service,' he said.
Paytouch is looking to open four more offices across Europe and the U.S. in the next 12 months.
Biometric authentication identifies humans using their physical traits or behavioural characteristics.
The analysis of fingerprints for matching purposes generally requires the comparison of several features of the print pattern, along with the structure and property of human skin
