# NFC Tag Reader: Unlocking the World of Contactless Data
I still remember the first time I used an **NFC tag reader**. It was for a university project where we had to create a smart poster. My personal experience with the technology was transformative; what seemed like simple "tap" functionality opened up a world of automation and data interaction I hadn't fully appreciated before. This personal journey from curiosity to practical application shaped my view on this essential tool.
## What is an NFC Tag Reader?
An **NFC tag reader** is a device or module that uses Near Field Communication (NFC) technology to wirelessly read and, in many cases, write data to passive NFC tags. It operates at 13.56 MHz and enables communication over a very short distance (typically less than 10 cm). My own skill in integrating these readers into various applications has become a valuable asset in my tech development work.
### Core Technical Specifications and Parameters
From my professional work, I can share that a high-performance **NFC tag reader** module, like those we often integrate, typically has the following technical indicators. *Please note: These technical parameters are for reference data; specifics need to be confirmed by contacting backend management.*
* **Chipset/Controller:** NXP PN7150 or ST25R3916 are common industry-standard NFC controllers.
* **Supported Standards:** ISO/IEC 14443 Type A & B, ISO/IEC 15693, FeliCa™ (JIS X 6319-4).
* **Operating Frequency:** 13.56 MHz ± 7 kHz.
* **Communication Interface:** I²C (standard speed: 100 kHz, fast mode: 400 kHz), SPI (up to 10 MHz), or UART (configurable baud rate).
* **Read Range:** Typically 30mm to 50mm, depending on antenna design and tag type.
* **Antenna:** Integrated or external; a typical external antenna might have dimensions of 50mm x 50mm with a recommended PCB coil design of 4 layers.
* **Power Supply:** 3.3V DC (±5%), with average operating current of 40-60mA during active polling.
* **Supported Tag Types:** NFC Forum Type 1-5 Tags (e.g., NTAG213, NTAG215, NTAG216, MIFARE Classic 1K/4K, MIFARE DESFire, ICODE SLI).
In my opinion, the choice of chipset and antenna design are the most critical factors determining the reliability and range of the **NFC tag reader**.
