# Tarjetas PVC NFC: The Ultimate Guide to Smart Card Technology ## What Are Tarjetas PVC NFC? **Tarjetas PVC NFC** represent a revolutionary fusion of traditional PVC card durability with Near Field Communication (NFC) technology. These smart cards contain embedded microchips and antennas that enable wireless data transmission when brought close to an NFC reader. From my personal experience implementing these cards for corporate access systems, I've witnessed firsthand how they transform ordinary identification into interactive tools. The seamless tap-to-authenticate functionality not only enhances security but significantly improves user convenience—a game-changer in environments requiring frequent access verification. ## Technical Specifications of Tarjetas PVC NFC ### Physical Dimensions and Construction - **Standard Size**: 85.6mm × 54mm × 0.76mm (ISO/IEC 7810 ID-1 format) - **PVC Thickness**: Typically 0.68mm to 0.84mm - **Chip Placement**: Embedded between PVC layers, positioned 19mm from top edge and 22mm from left edge - **Antenna Design**: Copper or aluminum coil with 3-6 turns, integrated within card layers - **Printing Surface**: High-resolution digital printing with scratch-resistant overlay ### NFC Chip Technical Parameters - **Chip Models**: NXP NTAG213, NTAG215, NTAG216; MIFARE Classic 1K; MIFARE DESFire EV2 - **Memory Capacity**: - NTAG213: 144 bytes user memory, 504-bit password protection - NTAG215: 504 bytes user memory - NTAG216: 888 bytes user memory - **Frequency**: 13.56 MHz (ISO/IEC 14443 A standard) - **Data Transfer Rate**: 106 kbit/s to 424 kbit/s - **Operating Distance**: Up to 10cm (typically 4-5cm optimal) - **Read/Write Cycles**: Minimum 100,000 cycles - **Data Retention**: 10 years minimum - **Security Features**: Password protection, encryption, unique 7-byte UID *Note: These technical parameters are reference data.
