RFID technology is replacing barcodes not only in the food sector but also in the logistics sector. RFID technology is not only used in industry, but was originally used in the military to identify active aircraft.
This innovative technology is based on a radio frequency identification system between objects, that is, using electromagnetic waves. These waves energize the tag, which stores the information, and can even modify it.
In general, passive RFID tags work as follows: the tag contains a chip and an antenna. When the antenna receives the electromagnetic waves, the information is sent from the tag to the RFID reader, which then sends this information, in this case, to the SGA program. The information sent by the tag is characterized by containing, for example, the batch number, issue date, etc.
But within this technology, it is divided into the type of electromagnetic waves. The most widely used method for package inventory is UHF (Ultra-High-Frequency), which transmits information more quickly. The problem is that it’s not used on metal surfaces or near liquids and organic materials. On the other hand, it is used on non-reflective surfaces such as plastics, wood, and glass, and non-absorbent surfaces such as cardboard and paper.
The use we’ll discuss today is inventory management. The information contained in the RFID tag prevents errors in the supply chain. Through the tags, multiple packages or loads can be tracked, collecting data that helps control the primary distribution of goods up to the last mile. This information includes location, speed, and security details. They are also useful for internal management, for example, helping with batch and date management and security features. For example, tracking packages on trucks to know exactly what part of the inventory generated by the WMS is on the truck and what route it will follow.
Another use of tags is to contain commands, such as unclogging a box, cleaning a photocell, or resetting the system. These labels or tags are located at various critical points of the conveyor machine, such as the exit, induction points, etc. Reading tags ensures the safety of the merchandise distribution process. In addition, they are also used for maintenance of conveyor machines or any other type of machine, for example, lubrication.
In conclusion, tags are used daily in the distribution and tracking of packages. These labels will enhance and revolutionize the logistics sector as we know it today.
