Radio Frequency Identification (RFID) is an identification system that uses radio frequency devices for tracking purposes. RFID system includes the tag, the reader and the writer.

There are several different types of RFID tags that cater to different purposes. There are active and passive tags with various degree of frequencies.

Passive Tags:

  • Unlike active tags, no battery needed
  • Smaller bracket/casing, customizable application
  • Shorter read distance than active tags (x<6meters)
  • # times tags can be rewritten with new data 100,000

(Left): RFID tags fit small enclosures of a base/floor/structure; (Center): RFID tags can be manually attached to steel beams, racks & gates; (Right): RFID tags nailed onto a wooden pallet

Active Tags:

  • Powered by battery
  • Larger bracket/casing
  • Longer read distance (x>30meters)

(Left): Live-stock identification; (Center): Mobile RFID reader; (Right): Active RFID tags securely identify asset

Frequencies & Read Range:

  • Low (125 KHz): x<1 meter
  • High (13.56 MHz) x<3 meters
  • Ultra High (850-900 MHz): 3-6 meters
  • Microwave (2.45 GHz): x>6 meters

One of the most commercially used tags are passive Ultra High Frequency (UHF) tags. Ultra High Frequency (UHF) tags typically offer better range than low frequency tags, can transfer data faster but use more power. Because they tend to be more "directed," they require a clear path between the tag and reader. UHF tags are often used on pallets of goods, gas tanks and other recycled containers as they pass through a specificied checkpoint in a warehouse/distribution center.

The main benefit over barcode is that RFID tags do not need to be scanned within the "line of sight", so tags can be scanned from greater distances and even during movements. This can significantly lower labour requirement and tracking errors. On the other hand, since traditional barcode label cost much less than a standard RFID tag (10cents usd - 50cents usd / 2,000 - 6,000 IDR), RFID is common in closed-loop enterprise supply chains where the tags are not discarded but are reused and rewritten.

A typical tag would carry around 2KB of data—enough to store some information about the item it is on. Hence, RFID tag can be useful to authenticate high value products (tires, apparel) in a discrete manner.

Radio waves bounce off metal and are absorbed by water at ultra-high frequencies. We can customize the casing for businesses that handle metal tanks to ensure smooth readibility (anti-metal & waterproof).
