+### 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.
