Although "vein scanning" might sound pretty intimidating, biometric identification systems are becoming more widely accepted as secure and alternative ways to pay. This vein scanner was developed by Fredrik Leifland, a student of Sweden's Lund University and now, the founder of Quixter.
There doesn't seem to be a name for Quixter's vein scanner just yet, but it could probably use one, since the payment system is completely non-invasive and only scans the unique vein patterns on the palm of your hand and has nothing to do with the veins on your insides.
The scanner still requires users to enter the last four digits in their phone number before scanning, but overall, the system seems like a much simpler way to pay. So far, the payment system has been introduced at 15 different locations on the Lund University campus, available for use by thousands of students.
