Swing-Pay: A Digital Card Module using NFC and Biometric Authentication for Peer-to-Peer Payment

 Advancement in payment technologies have an important impact on the quality of life. The emerging payment technologies create both opportunities and challenges for future. Being a quick and convenient process, contactless payment gained its momentum, especially in merchants, where throughput is the main important parameter. However, it poses risk to issuers as no robust verification method of customer is available. Thus giving rise to quests to evolve and sustain a wellorganized, efficient, reliable and secure unified payment system, which may contribute to the smooth functioning of the market by eliminating scratch in business. This article presents an approach and module by which one card can communicate with the other using Near Field Communication (NFC) technology to transfer money from payer’s bank to payee’s bank by digital means. This approach eliminates the need of physical cash and also serves all types of payment and identity needs. Embodiments of this approach furnish a medium for cashless card-to-card transaction. The module, which is called Swing-Pay, communicates with its concerned bank via GSM. The security of this module is intensified using biometric authentication. The article also presents an app on Android platform, which works as a scanner of the proposed module to read the identity details of concerned person, the owner of the card. We have also presented the prototype of a digital card. This card can also be used as virtual identity card (ID), accumulating the information of all ID cards including electronic Passport, Voter ID, and Driving License.
