# Dematerialized ID Card
## What is a Dematerialized ID Card?
A **dematerialized ID card** represents the digital evolution of traditional physical identification documents. It is a secure, electronic version of an identity card that can be stored and accessed on smartphones, tablets, or specialized digital wallets. From my personal experience transitioning from a physical wallet to a digital one, the convenience of having a **dematerialized ID card** accessible with a tap on my phone has been transformative, especially during travel or when applying for services online.
### The Technology Behind Modern Dematerialized ID Cards
The functionality and security of a **dematerialized ID card** rely on advanced technology. Here are the key technical specifications and parameters for a typical system:
**Technical Indicators & Detailed Parameters:**
* **Storage Format:** ISO/IEC 18013-5 (Mobile Driving License standard) compliant data structure.
* **Chip/Security Element:** Often utilizes a Secure Enclave (e.g., Apple T2/T3 chip, Google Titan M2) or an embedded Secure Element (e.g., NXP SmartMX2 P71 chip family) for private key storage.
* **Communication Protocol:** Near Field Communication (NFC) ISO/IEC 14443 Type A/B, Bluetooth Low Energy (BLE) 5.2+.
* **Cryptography:** Asymmetric cryptography (Elliptic Curve Digital Signature Algorithm - ECDSA with secp256r1 curve) and AES-256 encryption for data at rest.
* **App Container Size:** Approximately 50-150 MB for the full application with biometric templates.
* **Data Payload:** Typically 5-15 KB of structured data (personal details, portrait, issuing authority).
* **Biometric Integration:** Supports on-device matching via Face ID (TrueDepth camera system) or fingerprint sensor (ultrasonic or capacitive).
> **Important Note:** The above technical parameters are for reference data based on current industry standards. Specific implementations, exact chip codes, and detailed dimensions vary by manufacturer and government standard. For precise specifications for your project, you must **contact the backend admi
