Research Report: Existing Frameworks for RFID Tag Collision Detection

Frameworks for RFID Tag Collision Detection

  1. Arduino RFID Library

    • Provides basic communication functions with RFID tags, including collision handling.

  2. MFRC522 Library

    • Specifically designed for the widely used MFRC522 RFID chip, offering tag identification and collision handling functions.

  3. SparkFun Simultaneous RFID Tag Reader Library

    • Supports collision detection for the Simultaneous RFID Tag Reader, designed for easy integration into Arduino projects.

  4. Seeed Studio RFID Library

    • Compatible with various RFID modules from Seeed Studio, supporting collision detection.

Note: Collision detection is often automatic with RFID chips and readers, but specific implementation may vary depending on the module used.

Devices Capable of Multi-Scanning

  1. Impinj RAIN RFID-Reader

    • Known for advanced features including simultaneous reading of multiple tags.

  2. ThingMagic RFID-Reader

    • Industrial-grade readers supporting multi-scanning, capable of handling numerous RFID tags simultaneously.

  3. Alien Technology RFID-Reader

    • Designed for efficiency in handling a high volume of RFID tags across various industries.

  4. Zebra RFID-Reader

    • Built to read multiple tags simultaneously, part of Zebra's automatic identification and data capture solutions.

  5. Honeywell RFID-Reader

    • Offers RFID readers for diverse applications, including those supporting multi-scanning.

Example Projects (Arduino)

  • Basic RFID scanner example program (link provided).
  • Exploring the possibility of miniaturizing an RFID scanner to fit within 10mm^2, potentially wearable on a finger.
  • Identified small-sized RFID scanners (approx. the size of two fingers) from SparkFun Electronics.
  • Mentioned a potentially suitable RFID reader (link provided), seems expensive.

Potential Ideas

  • Placing Arduino on a table and using a handheld scanner connected via cable.
  • Developing a handheld/wearable RFID scanner, although integration methods with Arduino remain unclear.
