RFID Tags: What Are The Main Types?
We'll explain the difference between active tags, passive tags and more



Radio-frequency identification (RFID) tags are one of the most efficient methods used for tracking assets when it comes to ITAD. These tags can work by using cloud-based technology, and help to provide a much more accurate chain of custody.

There are two main types of RFID tags: active and passive. But what's the difference and how are they best used?

Active RFID tags: these tags operate using an internal battery and transmit their own signal in order to broadcast information. Active RFIDs are used on assets that need to be tracked over a long distance, as they can be read from a range of around 100m. Active tags are usually encased in a rugged shell as they have to endure harsh weather conditions. Some even have on-board sensors which allow the tracking of environmental parameters. But how they send information depends on the type of tag. There are two types of RFID tags: transponders and beacons. With a transponder tag, the reader will send a signal, then the transponder will send back a signal which contains information. These are more energy efficient as they only turn on when a radio signal is picked up. A beacon works by sending out information in real time, at set intervals.

Passive RFID tags: passive tags do not have their own battery, and draw energy from a reader which sends out electromagnetic waves. These tags are used when operating a reader from a short distance, as they only have a range of about 10m. Although there are many types of existing passive tags for different applications, inlays and hard tags are the mainstays. Inlays are very thin and can be stuck on most materials (aside from metal, as the metal may interfere with the return signal). Hard tags are made of durable materials such as thick plastic or metal. Overall, passive tags are far smaller, more cost-efficient and easier to manufacture than active tags.

It’s a good idea to look into purchasing these tags for a secure and efficient chain of custody within your ITAD workflow, bringing peace of mind to you and your customers.
