Giesecke+Devrient is a technology group that creates global payment transactions through innovative products and solutions. G+D partnered with Nascar to create an open access wristband that would be used at all events to give customers the freedom to make cashless transactions with a flick of a wrist, just like tap debit- and credit-card payments. It also allows users to tap their wristbands to enter contests or sponsored brand activations.
