Comprehensive Comparison of RFID Across Different Frequency Bands

What frequency bands does RFID have? What are the differences in performance?

RFID (radio frequency identification) is a technology that can read information without contact. For example, when you walk into the access control card swiping area, you don’t need to take out the card, just get close and the system can “recognize you”. However, RFID, like a radio, has different “channels” – that is, different frequency bands, and each frequency band has different uses and performances.

Common RFID frequency band comparison

1. Low frequency (LF: 125–135 KHz)
Recognition distance: very close, generally less than 1 meter

Recognize multiple RFID tags at the same time? No, you can only do it one by one

Transmission speed: relatively slow

Common scenarios: animal ear tags, access cards, stable recognition, but can only read and write a small amount of information

Features: strong penetration, not afraid of metal and water interference

2. High frequency (HF: 13.56 MHz)
Recognition distance: medium, about 1.5 meters

Multi-tag recognition: can read dozens or hundreds of tags at the same time

Faster speed: suitable for transactions and batch processing

Common scenarios: library, subway card swiping, mobile payment

Features: high security, can add passwords

3. Ultra-high frequency (UHF: 860–960 MHz)
This is the frequency band used by our product!

Identification distance: far, 6 to 12 meters or even farther

Multi-tag reading: can read thousands of tags at a time, high efficiency

Fast transmission: speed is about 600 times that of low frequency

Common scenarios: clothing management, washing tracking, warehouse logistics

Features: suitable for occasions requiring batch reading and writing and long-distance identification

Comprehensive Comparison of RFID Across Different Frequency Bands

What is our RFID tag like?

Our RFID tag belongs to the UHF type, using the NXP UCODE®9 chip, which is very suitable for work scenarios such as clothing tracking, laundry management, and linen management. Here are some key points:

Working frequency: 860-960 MHz, international standard

Reading distance: up to 6~12 meters, long-distance automatic identification, no need to get close to swipe the card

Material: soft fabric, suitable for sewing on clothes or linens, does not affect wearing or use

Installation method: can be heat-sealed or sewn

Chip capacity: 128 bits, can store enough identification information

Protocol standard: compliant with ISO 18000-6C, compatible with a variety of readers

Customization service: support OEM customization, including size, LOGO, color, etc.

Sample provision: spot samples can be provided for trial

To sum up

The UHF fabric tag we provide is specially designed for rapid identification of a large number of items such as laundry and linen management. It can make clothes have a “name” and “record” like an ID card. You don’t need to check one by one, just scan it with a reader to know where all the clothes have gone.
