Enhanced Data Security Through NFC-Based Storage Architecture in Modern Payment Credentials: Evolution, Implementation, and Implications

Abstract

Secure NFC-based data storage represents a pivotal advancement in payment card technology, enabling the protection of sensitive information through embedded chips rather than physical printing. This article explores the core concepts of NFC integration in payment systems, emphasizing standards compliance and fraud mitigation. By storing account details, CVV codes, and expiration dates within encrypted NFC chips accessible via authenticated applications or portals, this approach minimizes exposure to physical theft and skimming attacks. The discussion covers historical development from magnetic stripe cards to contactless systems, technical frameworks including ISO 14443 and EMV specifications, and real-world applications in retail and transit sectors. Implications include enhanced user control, reduced fraud rates, and alignment with regulatory requirements for data security. This concept not only bolsters transaction integrity but also supports broader societal goals of secure digital economies.
