# Tag 13.56 MHz: The Core of Modern RFID and NFC Technology When I first started working with RFID systems, I was fascinated by how a simple **tag 13.56 MHz** could unlock doors, make payments, and track inventory. My personal journey into this technology began when I developed a library management system, where the efficiency of these tags transformed a chaotic process into a streamlined operation. This experience solidified my view that **tag 13.56 MHz** devices are not just tools but enablers of seamless connectivity in our daily lives. ## What is a Tag 13.56 MHz? A **tag 13.56 MHz** refers to a radio-frequency identification tag that operates at the 13.56 MHz frequency band. This frequency is internationally standardized for short-range communication and is the backbone of both High-Frequency (HF) RFID and Near Field Communication (NFC) technologies. ### Key Technical Specifications and Parameters The performance of a **tag 13.56 MHz** is defined by its precise technical architecture. Below are the detailed specifications for a typical high-performance model. *Please note: These technical parameters are for reference data only. For exact specifications, you must contact backend management.* * **Operating Frequency:** 13.56 MHz ± 7 kHz * **Communication Protocol:** ISO/IEC 14443 A/B, ISO/IEC 15693, NFC Forum compliant (e.g., Type 1-4 Tag) * **Chipset Model:** NXP NTAG 216 * **Chip Code:** Integrated circuit with unique 7-byte UID * **Memory Capacity:** 888 bytes of user-available EEPROM * **Data Retention:** Up to 10 years * **Read/Write Range:** Typically 0 to 10 cm (dependent on reader power) * **Physical Dimensions:** 25.5mm x 14.5mm x 0.85mm (Standard Credit Card Form Factor) * **Antenna Type:** Embedded copper/aluminum coil * **Operating Temperature:** -25°C to +70°C * **Data Transfer Rate:** Up to 424 kbit/s ## My Skill in Deploying Tag 13.56 MHz Solutions One of my developed skills is integrating **tag 13.56 MHz** technology into bespoke business solutions. For instance, I designed an access control system for a corporate client using custom-formatted tags. My ability to program the memory sectors for encrypted credentials, rather than using off-the-shelf products, significantly enhanced th
