Summary

NFC passport verification is a secure and efficient method of authenticating identity documents using Near Field Communication technology embedded in modern e-passports, which significantly reduces fraud by cryptographically verifying data on the chip. The process is based on global standards like ICAO 9303, PACE, and BAC, which ensure interoperability and security by defining data structure, encryption, and access protocols. PACE enhances security against cloning attacks by digitally signing data, while BAC controls data access through keys derived from personal information. The verification process involves NFC initiation, PACE verification, BAC authentication, data extraction, and validation, resulting in a fast and automated system that minimizes manual processing time. Didit’s identity platform utilizes these standards to provide automated verification, global coverage, fraud detection, and seamless integration, offering real-time results to enhance user experience.
