Tips on RFID tags

updated:May 21, 2019



When introduced properly, RFID technology can help your company’s working efficiency to quickly outpace that of other companies who are currently using barcode scanning and product counting. For this reason, RFID has become increasingly popular over the last years.

However, when choosing equipment it is important to carefully research and consult previous scientific research and operational precautions. Otherwise, you might end up with a set-up that is completely impractical for your company. Let’s look at a few elements that you should take into account when making the decision about what kind of RFID set-up you are going to install:


Selection of RFID tags

Some materials and/or elements will interfere with the reading of RFID tags (e.g. if you want to attach them to metal scaffolding), the most basic type of tag won’t work for everyone. Of course, there are solutions for companies in these situations. For instance, there are tags that can actually use the metal in the scaffolding to amplify their own signal. So when selecting RFID tags, make sure to take a good look at the situation you want to use them in and be selective. Sometimes you’ll have to use stronger and/or specifically compatible tags, which might cost a bit more, but will work the best in the long run.

Instead of instantly installing a complete RFID set-up, it is very important to first test the tags on the actual operation site. Try reading an item on top of a wooden shelf and on a metal shelf and adjust your requirements depending on the results.


Placement of RFID tags

RF tags could be used in various departments, such as in distribution, inventory, logistics and manufacturing.

Tags that can be read from a long distance would be very useful and efficient when taking inventory, but would be overkill when applied to a regular distribution process.

If your processes do not require you to read tags at a distance, we recommend using a smaller RF tag. Generally, for RF tags, the smaller the size, the shorter the reading distance.

If you are using the RFID technology in many of your business departments and you therefore have different distance needs, we recommend using a function that reduces the radio wave output of the RFID reader. Another option would be to change the reader to the RSSI setting, which many believe to be more more efficient. By using the RSSI setting, instead of sending out a signal and reading the responses from the tags, the reader only measures the outputs of (the closest) tags.

RFID technology can be very useful for your company, but you’ll need to do some research to assess your own company’s needs. We offer multiple use cases you can consult to compare to your own company, so please have a look.

Apart from RFID reader/writers, we can also offer RF tag counseling. If you are interested in this, please contact us!
