How does it work? Well, a Uniqul tablet located at check-out stations will snap a photo of the customer as they approach, where it will take seconds for the tablet to process the biometrical data in order to locate the individual’s account within the database. This account is registered to a major credit card company, and the customer will then confirm the payment if the database sweep was clean, and press “OK”. It is tipped that this particular system will roll out in Helsinki, Finland, first, at checkout aisles and payment terminals before there is a chance of it appearing elsewhere. Apart from all major credit cards, a PayPal or Square account will also do when you register for a Uniqul account. It will cost you around $9 monthly to access the system regardless of where you are.
