What to Consider When Choosing RFID Tags & Labels for Your Application
Quality RFID Tags & Labels for Premium Performance
There are many considerations and options when installing a radio-frequency identification (RFID) solution including choosing the right RFID supplies. Factors such as location usage, application of media and environmental conditions, how the items are to be tracked, and where and what the tag will be applied to are a just a few of the considerations. These factors will affect what type of RFID supplies you will need to purchase for your installation.
RFID Tags & Labels
RFID tags contain at least three parts: an integrated circuit for storing and processing information that modulates and demodulates radio-frequency (RF) signals; a means of collecting DC power from the reader signal in the vicinity; and an antenna for receiving and transmitting the signal. The tag information is stored in non-volatile memory and can include either fixed or programmable logic for processing the transmission and sensor data, respectively.
RFID tags may either be read-only, having a factory-assigned serial number that is used as a key into a database, or may be read/write, where object-specific data can be written into the tag by a system user. Field programmable tags may be write-once, read-multiple; “blank” tags may be written with an electronic printer encoder. Many companies are opting to utilize smart labels with printed barcodes and human readable information which include the embedded RFID circuitry. Utilizing a smart label in an RFID installation optimizes the latest tracking technology in the marketplace.

RFID Tag/Label Types
Performance factors to consider when selecting RFID labels:
Inlay Size: A larger RFID inlay gives you longer read ranges.
RFID Reader Type: Handheld, fixed and overhead readers often perform differently and serve different use cases.
Material Surface and Environment: Surface of the material, such as corrugate box, wood, glass, plastic, metal, etc., as well as how densely items are stacked, or what is contained within the boxes, can affect the read range.
Passive RFID Tags
Passive RFID tags can operate on a Low Frequency (LF) and High Frequency (HF) band. These tags need to be in close contact to the reader antenna. In this near field region, the tag is closely coupled electrically with the transmitter in the reader. The tag can modulate the field produced by the reader by changing the electrical loading the tag represents. By switching between lower and higher relative loads, the tag produces a change that the reader can detect.
Active RFID Tags
Active RFID tags may contain functionally separated transmitters and receivers, and the tag need not respond on a frequency related to the reader’s interrogation signal. An active RFID tag has an on-board battery and periodically transmits its ID signal.
Passive RFID Tags
A battery-assisted passive RFID tag has a small battery on board and is activated when in the presence of an RFID reader.
