CCCD Chip Reading and Verification via NFC

This document highlights the CCCD Chip Reading and Verification via NFC details.

Objective

The CCCD Chip Reading and Verification via NFC module extracts user information from the chip embedded in CCCD National ID(NID) card (or a Citizen ID card) and validates it against the national database.

Did you know?

Near-field communication (NFC) is a short-range wireless technology that aides communication between NFC-enabled devices in close proximity to each other.

Input	Output
The following values associated with the user's NID: • ID Number • Date of Birth • Date of Expiry	The user's Personally identifiable information (PII) extracted from the national database, the associated verification status and the suggested action for the identity verification process. You can find the details of all the output fields under the success response details section.
