What Are RFID Tags?

RFID tags can be found in many forms of modern technology however, it is not quite clear what they are. We will explore RFID tags and their uses.

RFID tags can also be known as RFID chip. RFID stands for Radio Frequency Identification and the tags use radio frequency technology to transmit information to the receiving computer program. For an RFID tag to work, there needs to be a transmitter (such as a microchip) and a receiver (such as an antenna). RFID’s can be both passive and active transmitters. Passive RFID’s only transmit signals when they are scanned. Oppositely, active RFID’s constantly transmitted information, using battery power.

Active RFID’s are excellent tracking devices because they provide constant information at regular intervals. Examples of this are vehicle tracking devices, race trackers, movement trackers, and product tracking.

Passive RFID transmitters are great for business applications and only need to be scanned to provide the required information. These are good for things like tracking shipping information, product control, access and egress control, and files.

Active and passive RFID’s can be manufactured in a variety of sizes to suit their applications. This includes small, lightweight versions. The issue herein lies with the fact that there are no standards to which RFID’s have to meet, meaning they can be as flimsy or robust as the manufacturer desires.

All types of RFID tags can be put into two categories, passive and active, relying on the battery and scan activation. These can also be identified as RFID chips. RFID’s have multiple uses such as tracking devices for shipping and logistics or controlling access and egress to facilities.
