Application of Artifact-Based RE in Fortified Cards

Credit / Debit card transactions are one of the most widely used means for purchasing items. As such, security is a critical concern in redesigning systems that can improve the security of those transactions, and the involvement of the future users is important. In this paper, we demonstrate the use of Requirement Engineering (RE) techniques to include the user's acceptance of the security decisions before implementation, designing for ease of use, and making them aware of and responsible for their own security. We illustrate the application of a set of RE artifacts to elicit specific requirements for the security of the Fortified Cards, a revamped design of current credit/debit cards that uses QR code.
