Technology is a blessing when it comes to making a business process easy and efficient. One such blessing is an RFID Tag. It has made the complex and complicated task of keeping a track of inventory easier and simpler.

Many businesses take the benefit of this amazing technology to streamline many days to day business activities. If you havenít incorporated it into your business, then you should.

There are many types of RFID tags, but which one is perfect for you. Here is everything you need to know about different types of RFID tags, starting with an introduction for better understanding.

What are RFID Tags?

RFID stands for Radio Frequency Identification. It is a smart label that is used for tracking and storing a product or consignment. It uses radio waves to transfer data. It performs communication between a tag and a reader.

They are similar to barcodes, as they are also used to extract information and track an item or product. Unlike barcodes, tags use radio wave technology. Therefore, they donít need a direct line of sight to read, which makes them much easier to use for a large number of products.

Types of RFID Tags

There are many types of tags. Each one is suitable for different tasks, fields, and scales of a business. So here is a brief look at which can be the perfect choice for you.

Low-Frequency RFID Tags

These RFID Tags have the lowest frequency of just around 10cm. They have a 30 kHz to 300 kHz range, and they have a better performance with metal or liquids. It is ideal for businesses that need only short tracking.

High-Frequency RFID Tags

These run on a range of 3 MHz to 30 MHz and have a range of 10cm to 1 meter. They are ideal for a medium range of contact. Popularly used in hotel key cards, payment cards, security systems, tracking bracelets in theme parks etc.

Ultra-High Frequency RFID Tags

These ones have the highest frequency ranging from 300 Mhz to 3 GHz. Ultra-high frequency RFID tags have a range of up to 12 m, and they have a faster data transfer rate and are very affordable. The most common uses of UH tags are inventory tracking and pharmaceutical anti-counter fittings.

Passive & Active RFID Tags

These are a little different from the ones mentioned above. They both are different but hold some similarities to each other, which also helps them stand out among other tags.

Active RFID Tags have batteries and periodically transmit signals. They are very useful in tracking applications. Active RFID tags have a long range of up to 100 meters, as the battery in them tend to boost their signal strength.

Passive RFID tags are dormant till they receive a radio signal. A signal from the receiver can turn them on, and then they send signals that carry information back to the receiver.

Active RFID Tags tend to be expensive. Therefore they are used only for tracking expensive consignments and items. On the other hand, passive tags are used for products and pallet labels.
