RFID Technology: What is it, how it works and how it can benefit your business?

RFID (Radio Frequency Identification) has become an increasingly important tool for businesses in 2019. It almost seems like a bar-code however, it is much, much more.

A RFID system uses tags which are attached to the objects to be identified. Two-way radio transmitter-receivers called readers send a signal to the tag and read its response via radio waves. This technology is categorised in a group called Automatic Identification and Data Capture (AIDC). Technologies within this category identify objects, collect their data and enter that data directly into computer systems saving time and potentially saving money over time. This system contains three main elements: a RFID tag, RFID reader and an antenna.


RFID tags consist of an integrated circuit and an antenna which can be used to transmit the data to the reader, which then converts the radio waves to a more usable form of data which gets transferred and stored into a host computer ready for analysis. These tags come in two forms, passive and active. Passive tags are smaller and less expensive to implement but must be powered up by the reader before they transmit the data to the host computer. In comparison, active tags have a constant power supply usually, through a battery and can transmit data at all times.

The most noteworthy advantage over other data identification systems is that the RFID code can be transmitted and read outside the line of sight. Others include a long read range, portable databases, multiple tag reads, carry large data capabilities, contain a high level of security as data can be encrypted or password protected and the tag can withstand harsh environments which might make other methods such as barcodes harder to read.

RFID technology can be an important aspect for improving your business as not only does it prevent errors as it can be done automatically and therefore reducing the risk of human error, it can also provide real-time data which can be analysed at any time. As this is completed in real-time, companies can become better and more accurately informed potentially leading to better decision making.

We have utilised this technology with many clients in many different industries. One of these clients is Orca Subsea where we created an application that handles not only, the administrative side of shipping items but for client interaction and updates.
