# RFID in Passport ## What is RFID in Passport Technology? **RFID in passport** refers to the use of Radio-Frequency Identification technology embedded in modern passports, often called e-Passports or biometric passports. From my personal experience traveling internationally, the convenience of e-Passport gates is undeniable, drastically reducing queue times at immigration. However, I've also felt concerns about data security, knowing my personal information is stored on a chip. ### How RFID Passports Work: A Technical Overview The **RFID in passport** system involves a small microchip and an antenna embedded in the passport's cover or data page. This chip stores the holder's biographic information and a biometric identifier, such as a facial image. During border control, a reader emits a radio wave that powers the chip (passive RFID) and retrieves the encrypted data for verification against the physical document and the holder. #### Key Technical Specifications and Parameters Providing the technical details for the RFID chip used in passports requires referencing common industry standards. The following parameters are typical for such applications: * **Chip Type:** Typically a secure microcontroller chip compliant with ICAO (International Civil Aviation Organization) Doc 9303 standards. * **Communication Protocol:** ISO/IEC 14443 Type A or Type B (Proximity Coupling Device). * **Operating Frequency:** 13.56 MHz (High Frequency - HF). * **Memory Capacity:** Ranges from 32KB to 128KB of EEPROM to store data and cryptographic keys. * **Data Structure:** Includes Data Groups (DG1: MRZ data, DG2: Encoded facial image, DG3: Fingerprints, etc.). * **Security Features:** Passive Authentication (PA), Active Authentication (AA), Chip Authentication (CA), and Terminal Authentication (TA). Uses Basic Access Control (BAC) or Password Authenticated Connection Establishment (PACE) to establish a secure channel. * **Antenna:** Embedded as a thin wire coil, dimensions are tailored to the passport booklet size, typically within a 85mm x 54mm area (standard passport page size). > **Important Note:** The technical parameters above are for illustrative and reference purposes based on common industry standards.
