You have heard of many ways to pay for what you buy without using cash. From debit and credit cards, to paypal to contactless cards. Now there is another way we might be paying in the future. Sometime soon, you might walk into the supermarket and pay by waving your hands at a scanner. You don’t need to have a computer chip under your skin either. Swedish engineer Fredrik Leifland invented a system that scans your vein patterns and recognises it as a payment method. This unique system called Quixter uses sensors that are used to read the configuration of blood vessels and correspond with the linked bank account.

Conclusion: This is a very unique system that has been tried by many students in Sweden and has become popular. As a security enthusiast, I consider this to be a very secure payment system that can and will become very popular in the future.
