Can RFID Tags Be Read by All RFID Readers？

2025-05-01Cykeo News RFID FAQ 6100

No, RFID tags cannot be universally read by all RFID readers due to differences in frequency, communication protocols, and tag-reader standards. Compatibility depends on aligning the technical specifications of tags and readers. Here’s a detailed guide to RFID interoperability and how to avoid mismatches.

1. Why Compatibility Varies

Frequency Mismatch:
- LF (125 kHz): Used for animal tracking and access control.
- HF (13.56 MHz): Common in NFC, payments, and library systems.
- UHF (860–960 MHz): Ideal for logistics and retail inventory.
- A UHF reader cannot read LF/HF tags, and vice versa.
Protocol Differences:
- Tags and readers must support the same air interface protocol (e.g., ISO 14443 for HF, ISO 18000-6C for UHF).
Tag Memory Structure:
- Some readers lack software to decode proprietary data formats.

2. Key Compatibility Factors

Factor	Impact	Example
Frequency	Determines read range and use case	UHF for warehouses, HF for NFC
Protocol	Ensures communication between tag/reader	ISO 15693 vs. ISO 18000-6C
Power Output	Affects read range and tag activation	High-power readers for bulk scans
Regional Standards	UHF frequencies vary by country (e.g., EU vs. US)	FCC vs. ETSI regulations

3. Solutions for Universal Compatibility

Multi-Protocol Readers:
- Cykeo’s OmniScan Series supports LF, HF, and UHF frequencies, enabling cross-industry applications.
Firmware Updates:
- Update reader software to add new tag protocols or regional settings.
Tag Standardization:
- Use GS1-compliant tags (e.g., SGTIN-96) for global supply chains.

4. Testing Compatibility

Check Specifications:
- Verify tag frequency (e.g., 902–928 MHz for UHF in the US) and reader range.
Conduct Pilot Scans:
- Test tags in real-world conditions (e.g., metal shelves, liquid containers).
Use Cykeo’s Validator Tool:
- Free software to audit tag-reader compatibility across protocols.

5. Case Study: 95% Inventory Accuracy

A retail chain achieved 95% inventory accuracy using Cykeo’s multi-protocol readers to scan mixed HF (NFC loyalty cards) and UHF (apparel tags) systems.
