Benefits Of Tags

Benefits Of Tags
Tags, specifically RFID tags were developed as a substitute to the common bar codes technology. Tags are basically unpowered devices responsible for bouncing back a certain code every time they are struck with a signal from a device that transmits radio frequencies. Different from bar codes, tags are readable from any location provided they are in range. The following are benefits of tags.

1. Simplified reading
An employee walking through an occupied warehouse can see what is in all the crates without needing to climb over or opening any crate. RFID devices are able to work regardless how the tag is placed. In fact, RFID devices can work through huge barriers like walls. Since the device reveals a specific code only, an individual with a RFID reader but lacking the appropriate list cannot really see the contents of a certain crate.

2. Law enforcement
Tags also provide several benefits in the field of law enforcement. For instance, in Canada, the police are already making use of these RFID tags for ticketing speeders. In this case, the tag is mounted on vehicles and roadside devices are set up at fixed distances. As the vehicle passes every checkpoint, it is easily recognized by the devices. By calculating the total speed of vehicles through between each checkpoint, the system then sends a traffic ticket to the owner of the vehicle if their speed was over the set limit.

3. Highly durable
RFID tags are much more durable in contrast with using bar codes. This is because RFID tags are usually better protected and at times they are internally attached, enabling easy reading even in very harsh environments. Conversely, bar codes are not resilient as they are easily removable.

The demerit associated with using RFID tags is that they are more costly than substitutes like the bar code system. Using active tags is even more expensive because of their complexity.
