Introduction to RFID Technology

If you are considering an automated means to verify and track your fixed assets, RFID (radio frequency identification) might be the right solution for you.

In this blog series, we will identify the benefits as well as the potential drawbacks with this technology. To begin, it is important to understand that the technology utilizes radio waves to send and receive information.

RFID represents the wireless, non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking [RFID] tags that are attached to objects. The tags contain electronically stored information. Unlike a barcode, the tag does not need to be within line of sight of the reader to be read.

Radio waves can be transmitted within various frequencies, which are regulated by governmental bodies. The most common frequencies include; low frequency (LF), high frequency (HF) and ultra high frequency (UHF).

The most common use for the LF and HF frequencies are related to access control and will not be discussed in this blog series. Our focus will be on the use of UHF RFID as this is widely-used for tracking inventory and assets alike.

Follow our daily blog series as we explore; reliability of RFID technology, RFID tags, mobile and stationary RFID readers, and the processing of information.
