RFID / NFC Modules
20 products
RFID (Radio-Frequency Identification) and NFC (Near Field Communication) technologies provide indispensable solutions for wireless data transfer and object identification. In this category you'll find RFID reader/writer modules operating in low frequency (125 kHz), high frequency (13.56 MHz) and ultra-high frequency (860–960 MHz) bands, NFC tags, contactless smart card readers, and integrated development kits. Easily interfaced with platforms like Arduino and Raspberry Pi, these components are preferred in projects ranging from access control to inventory management.
Which Application Requires What?
- Access Control & Personnel Tracking: 125 kHz EM4100 or 13.56 MHz Mifare card readers are ideal for door entry and attendance tracking systems. A read range of 5–10 cm is usually sufficient.
- Inventory & Logistics: UHF RFID readers can read multiple tags at distances up to 10 metres, offering high efficiency in warehouse management, pallet tracking and retail stock counting.
- Payment & Identity Verification: NFC modules communicate with smartphones and are used in contactless payment, identity verification or device pairing (Bluetooth/Wi-Fi handover).
- Animal & Livestock Tracking: Low-frequency biocompatible glass tags and handheld readers are common in veterinary and farm management.
Points to Consider When Choosing
To select the right RFID/NFC component, first check the operating frequency and supported tag protocols (Mifare Classic, NTAG21x, ISO15693, EPC Gen2, etc.). The reader's communication interface (UART, SPI, I2C, USB, RS232) must be compatible with your project's controller. Read range, antenna design and environmental conditions (metal surfaces, liquids) directly affect performance. Especially in industrial applications, factors such as temperature tolerance and ingress protection (IP) rating should also be taken into account.
