Biometric recognition provides means to guarantee security in a wide range of services. Unfortunately, though systems based on face or fingerprint recognition are already integrated in the society, their usability is limited and they are not convenient for people with accessibility issues. In order to prevent the slow penetration of biometrics or even the rejection of the technology, those systems should be improved by using a user-centric-design approach and by applying current usability and accessibility standards. This work describes the design, development and evaluation (both accessibility and performance) of a mobile app for making payments in Points of Sale (PoS) using fingerprint and handwritten signature recognition. The system has been tested by elderly persons. Our findings show accessibility issues in security related environments, and the most critical requirements to be covered. This research is one of the first published accessibility evaluations based on the recently publish European standard EN 301 549.
