Learn about RFID Labels to use them for their intended purpose

What is RFID label :


  • RFID (Radio frequency identification): is a collection of smart labels that includes near-field communication (NFC) tags, ultra-high frequency (UHF) tags and more .
  • If you are considering implementing an RFID solution, it is important that you understand the differences between each type of RFID.
  • Choose a partner with experience in advising on the right card type for your business application.

2. So what is an RFID label/tag?

  • RFID technology relies on radio waves to send and receive information between the label and reader.
  • At the simplest level, the RFID reader will send a signal to the RFID label and the label will send back a signal carrying the information.
    Unique information is provided as a GS1 Electronic Product Code™ (EPC)
  • can be programmed into individual RFID tags that are then attached to products, boxes, pallets.
  • Or even high-value devices depending on the application.
  • RFID technology can be understood as barcodes, similar to barcodes.
  • Tags RFID are often used to quickly trace product-level information.
  • However, becauseRFID tags use radio wave technology, they do not require a direct line of sight to read.
  • Meaning that an entire pallet or load of products can be read as fast as 700 products per second.
    This gives RFID tags a clear advantage when it comes to driving supply chain tracking and optimization (known as smart label tracking).
  • In addition to distribution and supply chain benefits, many brands are taking advantage of RFID tags to engage customers in the experience.
  • Allow consumers to scan labels to access educational programs or product-specific pages.

3. Types of RFID labels

  • In terms of frequency range, RFID labels have 4 different types:
  • NFC (near field communication): near field communication card
  • LF (low frequency): low frequency
  • HF (high frequency): high frequency
  • UHF (ultra-high frequency): super high frequency

4. application, there are 3 types of RFID labels

  • Active:
    • powered – has a battery and transmits signals periodically, useful in location tracking applications
    • The battery in the active tag can increase the signal strength, the tag has a longer reading range, up to 100 meters.
    • With the most expensive cost, this type of card is often used to track very high value assets:
      • Construction equipment, automobiles or healthcare applications
  • Passive:
    • no power – the tag only works when it receives a radio signal from the reader
    • Energy from the reader signal is used to turn on the tag.
    • Transmits a signal that carries information back to the reader.
    • Often used in tracking goods and pallets at low cost.
  • Semi-passive:
    • battery support – tag has a battery but does not transmit signals periodically like active RFID tags,
    • Instead, the battery is only used to turn the card on when a signal is received
    • This allows all the energy from the reader’s signal to be transmitted back.

5. Criteria for selecting a suitable RFID Tag:
  • RFID tag frequency matches your needs.
  • The size of the RFID label is suitable for the product to be affixed.
  • Type of device to be pasted (Metal, non-metal).
  • Single use or reuse.
  • Adhesive strength for RFID Labels
  • Product cost and investment level.
