How many types of RFID tags are there? 4-band selection guide + 5 application categories + 3 comparison tables
💡 💡 At a Glance
RFID tags are classified by frequency into three categories: low frequency, high frequency, and ultra-high frequency. By power supply, they are divided into passive (accounting for over 90%), active, and semi-active types. Ultra-high frequency is suitable for warehousing and logistics, high frequency is suitable for anti-counterfeiting and traceability (NFC compatible), and low frequency is used for animal identification.
Last week, a warehouse-management client asked me: "I want to attach RFID to every shelf in my warehouse—which frequency band should I choose?"
I said: "It depends on your distance requirement—4 frequency bands correspond to 4 distance categories."
He asked, "How do I choose among the 4 frequency bands?"
I said: "A decision tree plus a 5-step process—choose right and save 30% in cost. This article won't explain 'what RFID is'—it covers a 4-band selection decision tree + comparison of 5 application categories + 3 types of RFID tags + a 5-step implementation process."

FAQ
What are the types of RFID tags?
4 Major Frequency Bands of RFID Tags: (1) LF Low Frequency 125-134 kHz — strong penetration, read range 10 cm (animal tags / access control cards); (2) HF High Frequency 13.56 MHz — medium range, read range 10 cm-1 m (NFC payment / ID cards / libraries); (3) UHF Ultra-High Frequency 860-960 MHz — long range and high speed, read range 1-10 m (warehousing / logistics / retail); (4) Microwave 2.45 GHz/5.8 GHz — extremely fast but expensive (ETC highway tolls / airport baggage). 3 Selection Categories: (1) Short range (access control / payment) — HF/NFC; (2) Medium range (warehousing) — UHF; (3) Long range (highway tolling) — microwave.
What are the differences between RFID and NFC?
3-Dimensional Differences: (1) Frequency band — NFC is a subset of HF 13.56 MHz, operating distance ≤ 10 cm; RFID covers 4 frequency bands of LF / HF / UHF / microwave, with UHF distance of 1–10 m; (2) Communication — NFC supports two-way communication (mobile phone reading + writing), while RFID is primarily one-way (reader reads + tag responds passively); (3) Protocol — NFC complies with ISO 14443 (compatible with bank cards), RFID UHF complies with EPC Class 1 Gen 2. 3 Categories of Applications: (1) NFC — mobile phone tap-to-pay (Apple Pay) / access control cards; (2) RFID HF — ID cards / library; (3) RFID UHF — warehousing and logistics (long-distance). 3 Categories of Cost: NFC tags 0.5–3 RMB vs. UHF tags 0.5–5 RMB.
How much data can RFID tags store?
4. Different capacities by frequency band: (1) LF 64 bits (8 bytes) — minimum, stores only ID; (2) HF 1–8 KB (NFC ISO 14443) — stores ID + simple data; (3) UHF 96–512 bits (EPC) — stores EPC + TID + user memory; (4) Microwave 1–64 KB (special applications) — stores large amounts of data. Three typical capacity categories: (1) Logistics label 96 bits — stores only EPC code (GS1); (2) Membership card 1 KB — stores ID + balance; (3) Industrial tag 8 KB — stores process parameters + serial number. Three key points: (1) Larger capacity means higher cost; (2) Capacity affects read speed (the larger, the slower); (3) Capacity determines scalability (upgrading data requires capacity).
Which frequency band should be chosen for RFID tags?
4-Category Decision Tree: (1) Distance requirement — ≤10cm, choose HF / NFC (access control / payment); (2) Distance requirement 1-10m, choose UHF (warehousing / logistics); (3) Distance requirement 10m+, choose microwave (ETC / airport); (4) Penetration requirement (metal / liquid), choose LF or specialized anti-metal tags. 3 Key Decision Points: (1) Frequency band determines distance + speed + anti-interference; (2) Tag cost LF < HF < UHF < microwave; (3) Reader cost LF < HF < UHF < microwave. 3 Typical Scenarios: (1) Access control / payment — HF/NFC; (2) Warehousing / logistics — UHF; (3) ETC / high-speed — microwave.
How to Test RFID Tags?
3-Step Standard Test: (1) Read Distance Test – read 5 tags at different distances (< 1m fail / 1-5m normal / > 5m excellent); (2) Bulk Read Test – read 100 tags simultaneously (> 95% success rate qualified); (3) Environmental Test – read under metal / liquid / high temperature (mandatory for special scenarios). 3 Types of Test Tools: (1) Reader + tag distance ruler (simplest, 100 RMB); (2) Bulk Read Tester (professional, 10,000+); (3) RFID Testing Laboratory (professional-grade, 50,000+). 3 Test Standards: (1) Read success rate ≥ 99%; (2) Distance meets standard (by scenario); (3) Environmental anti-interference (by scenario). Recommend mandatory testing for each supplier + quarterly spot checks.
