Contactless ticketing and pre-payment using Mifare UltraLight C and Prox’N’Roll

Last saturday, SpringCard Prox’N’Roll PC/SC was the core component of the access control and payment system during the annual gala of french high-school École Centrale d’Électronique (ECE) located in Paris. NXP Mifare UltraLight C chips were embedded in the disposable wristbands (featuring the SpringCard logo) that were worn by 3000 attendees.

The team appears in a short video that aims to promote the concept :
