RFID technology is always developing and advancing to make it easier to incorporate in newer fields and easily. One of the latest advents in RF technology is the new RFID Flag Tags. These tags are extremely resistant to disruption-causing environments like liquids, metals, etc., in addition to not being affected by them, they use such obstacles to their advantage.
So, let’s discuss them.
What are RFID Flag tags?
These are the new upcoming class of RFID tags, developed to provide traceability and identification services on a variety of surfaces. Unlike average tags, these do not completely adhere to the surface, instead, they can be folded, and a part of the tag adheres to the objects, and the remaining part sticks above the surface of the object.
These tags have two antennas, one part of attached to the surface of the object and the other one sticks out in the air. This property of the tag, allows it to work on almost every type of surface. Not only that but use the issues that arise with metal surfaces in general circumstances to their advantage.
Applications & Benefits of RFID Flag tags
With its unique design and properties, flag tags are compatible with a variety of operation niches. Unlike most other type of tags, these provide exceptional performance and are very resistant to signal degradation and distortion.
(A). Retail
RFID Flag Tags are very popular in the retail industry for the identification & tracking of consumer goods. From small to large operations, flag tags are compatible with most facilities.
(B). Item Level Tracking
Due to their simple design, fast read speed, and low cost; businesses can utilize flag tags for item-level tracking operations. Having item-level tracking capabilities allows users to maintain clear and efficient visibility over the movement of the inventory management operations.
(C). Metal Surfaces & Liquid Containers
Flag tags have two antennas, one of the antennas sticks out of the object like a flag and the other adheres to its surface. The tag uses the metal surface of the object to act as an extension to its antenna. This helps it increase the strength of its signal by reflecting more signals, increasing the range of the transmission.
By having a second antenna that sticks away from the objects, these tags can also be used to track containers with liquid inside them.
(D). Printer Compatible
RFID Flag Tags are very similar in appearance to wet inlays; in that they consist of an RF inlay, covered by a protective substrate layer and a layer of adhesive. These tags are very slim and have the capability of working along an RFID printer. They are easy to encode using the NFC reader inside the printer.
Conclusion
RFID flag tags are advanced RF tags that are popular in use in a variety of applications and industries. These tags are slim and can be stored in rolls, providing them the benefit of being used as roll-to-roll labels and compatible with thermal printers, all the while also providing tracking capabilities with metallic surfaces.
These tags are cheap, easy to use, and compatible with almost all types of objects, making them perfect for use in environments with lots of obstacles and metals.
Frequently Asked Questions
Q1. What is an RFID flag?
An RFID flag is a type of RF label/tag that is folded before application. The shape of these tags allows them to have a part of their surface sticking out from the object. This property allows them to counter the signal distortion effect of metal surfaces & liquids.
Q2. What are the two types of RFID tags?
RFID tags can be of two types based on their functioning, namely – active & passive. Active tags have an internal power supply that allows the tag to broadcast its signals. On the other hand, passive tags use radio backscattering or the energy from a reader’s signal to broadcast a signal.
Q3. What is the range of RFID?
The range of RFID tags can vary depending on factors like frequency, antenna output, size of tag, type of tag, environmental factors, etc. In ideal conditions, an NFC tag can have a communication range of a couple of centimeters, while an active tag can have a read distance of up to 100 meters.
