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 don’t 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

Thеre are many types of tags. Each onе 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
