What is an RFID Tag? From WWII Radar to Bubble Tea Cups: A 70-Year History of Technology Evolution
💡 💡 At a Glance
Detailed explanation of RFID tag working principles, frequency classifications, application scenarios, and comparative analysis with barcodes
Last week, a client working on smart packaging asked me: "Is RFID a recent invention? Why is it suddenly so popular?"
I said: "RFID is not a new technology — it is already 70 years old."
He said, "70 years?"
I said: "In 1935, the UK used radar to identify aircraft; in 1948, Harry Stockman published his radio-frequency identification paper; in 1973, the first commercial RFID tag appeared; in the 2000s, it went into large-scale civilian use; by 2024, RFID is an 'old technology' in its 80s. This article won't cover how it works — it will walk through 70 years of technological evolution, so you can see how it moved from military use to milk tea cups."
RFID 70-Year Evolution Timeline
Stage 1: Military Radar Era (1935–1970)
1935: The UK used radar to identify incoming aircraft — this was the conceptual origin of RFID.
1948: Harry Stockman published the paper "Communication by Means of Reflected Power" — laying the theoretical foundation for RFID.
1950s–1960s:
- 1950s: The US military researched IFF (Identification Friend or Foe) — to identify friendly or enemy aircraft
- 1960s: The Soviet Union used RFID to monitor livestock (the earliest application of animal tags)
- 1969: Mario Cardullo filed the first RFID tag patent
Characteristics: Purely military use, high price (over $100 per tag), large size.
Stage 2: Commercial Electronic Tag Era (1973–2000)
1973: Mario Cardullo invented the first commercial RFID tag — used for warehouse management.
1980s:
- Early 1980s: ETC electronic toll collection on US highways (Amtech company)
- 1987: Norway's first commercial RFID toll system
- 1990s: RFID entered access control, animal identification (pet chips), and libraries
1999: The MIT Auto-ID Lab proposed the "Internet of Things" concept, with RFID as a core identification technology.
Characteristics: Cost dropped to $1–$10 per tag, beginning civilian use, but limited to professional scenarios.
Stage 3: Mass Adoption Era (2000–2015)
2000s:
- 2003: Walmart required suppliers to use RFID tags (the biggest single driver)
- 2004: The global RFID market size exceeded USD 1 billion
- 2006: Europe mandated RFID ear tags for livestock
- 2008: China's second-generation ID card embedded RFID
2010s:
- 2013: NFC (a 13.56 MHz high-frequency RFID subset) was built into smartphones, beginning to replace access cards
- 2014: Apple Apple Pay used NFC to drive mobile payment
- 2015: ZARA, H&M, and Decathlon deployed RFID for inventory counting
Characteristics: Cost dropped to CNY 0.5–3 per tag, with annual shipments reaching tens of billions.
Stage 4: Smart Packaging Era (2016–Present)
2016 to present:
- 2016: RFID + sensors (temperature/humidity) entered cold-chain food monitoring
- 2018: RFID + blockchain used for luxury goods traceability
- 2020: COVID-19 drove the explosive growth of RFID in healthcare and retail
- 2023: RFID + AI cameras enabled unmanned stores (e.g., Amazon Go 2.0)
Future Trends:
- RFID unit price will fall below CNY 0.1 per tag (in large volumes)
- RFID combined with printed electronics will drive the spread of "smart packaging"
- RFID direct printing (no additional labeling required)
Characteristics: Upgraded from "identification" to "sensing + traceability + interaction".
4 RFID Frequency Bands (by Evolution Timeline)

Characteristics: Strong penetration (works through liquids and metals), range of 10 cm
Applications: Animal tags, access control cards, car keys
Representative Products: Pet microchips, car anti-theft keys
Band 2: High Frequency HF (13.56 MHz)
Representative Era: 1990-Present
Characteristics: Medium range, globally unified standards (ISO 14443, ISO 15693)
Applications: NFC payment, ID cards, passports, libraries
Representative Products: Apple Pay, second-generation ID cards
Band 3: Ultra-High Frequency UHF (860-960 MHz)
Representative Era: 2000-Present
Characteristics: Long range (10 m), high speed (batch reading of 100+ tags)
Applications: Warehousing and logistics, retail inventory, anti-counterfeiting
Representative Products: ZARA tags, Decathlon tags
Band 4: Microwave (2.45 GHz / 5.8 GHz)
Representative Era: 2010-Present
Characteristics: Fastest, longest range, most expensive
Applications: ETC highway toll collection, airport baggage tracking
Representative Products: Highway ETC tags
5 Modern Application Scenarios
Application 1: Warehousing and Logistics
Frequency Band: UHF
Case Study: JD.com's "Asia No.1" warehouse uses RFID for inbound inventory—scans 100 parcels in 1 second.
Application 2: Retail Anti-Theft
Frequency Band: UHF + EAS (Electronic Article Surveillance)
Case Study: Decathlon tagged 7 billion items with RFID—inventory accuracy improved from 95% to 99.9%.
Application 3: Medical Tracking
Frequency Band: HF (including NFC)
Case Study: RFID for surgical instruments—counting 50 surgical forceps reduced from 30 minutes to 3 minutes.
Application 4: Food Cold Chain
Frequency Band: UHF + Temperature Sensor
Case Study: Fresh produce e-commerce cold chain monitoring—automatic alert when transport temperature exceeds 8°C.
Application 5: Smart Packaging / Interactive Marketing

FAQ
What is RFID?
RFID = Radio Frequency Identification. It automatically identifies information on tags via radio waves, requiring no contact and no line of sight. Core components: reader + tag + antenna. Harry Stockman's 1948 paper laid the theoretical foundation, but commercialization did not appear until 1973 (for warehousing and access control). Today, global RFID tag shipments exceed 20 billion units per year.
What is the difference between RFID tags and barcodes?
Key differences: (1) Capacity — barcodes hold 13-30 characters, RFID up to 8 KB (can store URLs, product info, sensor data); (2) Reading — barcodes scan one at a time, RFID can scan 100+ simultaneously (batch); (3) Distance — barcodes require close-range front-facing scans, RFID reads from 1 cm to 10 m; (4) Contamination resistance — scratched barcodes fail to scan, RFID is unaffected by appearance; (5) Cost — barcodes 0.05 RMB, RFID 0.5-5 RMB.
How many frequency bands do RFID tags have?
4 main frequency bands, each with its application: (1) Low Frequency LF 125-134 kHz — strong penetration, suitable for animal tags and access control cards (read distance 10 cm); (2) High Frequency HF 13.56 MHz — medium distance, suitable for payments, ID cards, NFC (10 cm-1 m); (3) Ultra-High Frequency UHF 860-960 MHz — long range and high speed, preferred for warehousing and logistics (1-10 m); (4) Microwave 2.45 GHz or 5.8 GHz — fastest but most expensive, suitable for high-speed tolling and ETC.
How much do RFID tags cost?
Costs across 3 dimensions: (1) Bare tags — 0.5-3 RMB/unit (including chip + antenna); (2) Readers — fixed type 1,000-5,000 RMB per unit, handheld type 500-2,000 RMB per unit; (3) System integration — database + software 50,000-500,000 RMB per project. Beginners can experiment with HF NFC tags (0.5-1 RMB/unit), then upgrade to UHF for bulk use (0.3-0.5 RMB/unit).
Can RFID tags be used in retail?
Yes, but with thresholds. Retail giants like ZARA, H&M, and Decathlon have already scaled RFID for inventory counting (reducing counting time from 7 days to 1 day). Retail RFID challenges: (1) Tag cost must be controlled within 0.5% of the product price; (2) Tamper-evidence + anti-transfer (preventing tags from being peeled off and attached to other products); (3) Compatibility between consumer self-scanning and staff inventory workflows. It is recommended to pilot with products priced above 100 RMB.
