FAQs

What is RFID?
RFID, or Radio Frequency IDentification, is a data collection method that utilizes low power radio waves to send and receive data between tags and readers.

By using radio signals, RFID eliminates the need for a direct line of sight to the tag in order to read it. RFID readers can simultaneously read and write to hundreds of tags within their read field.

How does RFID work?
RFID uses a reader to locate and track special tags or labels attached to an item, similar to a bar code system. Instead of collecting laser light reflections off printed bar code labels, RFID uses low wattage radio frequencies to read from and write to the tags.

The RFID tags, or labels, equipped with an RF antenna and a tiny computer chip, broadcast information to the RFID reader. These broadcast radio waves do not require a direct line of sight or one-at-a-time labor intensive involvement. Tags do not have to be in contact with the device that "reads" the information stored on the chip.

What is a UID?
Unique Item Identifier (UID) tags contain an E.I.D. (Cage Code or Mfg. Cage Code), a serial # assigned to the item, and the part number associated with the item.        

What is an RFID Tag?
In general, an RFID tag consists of an application-specific integrated circuit (IC) with memory chips used for data storage and an antenna that can be mounted on various substrates. Each element of an RFID tag is selected for optimum efficiency for the application.

Physical sizes can range from as small as a thumbnail to as large as a brick. Most of today's tags offer up to 1024 bits of memory and read ranges up to 18 feet, dependent upon the application. The term "tag" and "transponder" are synonymous.        

What are the benefits of using RFID technology?
RFID-enabled systems help companies cut costs, improve customer service, reduce labor, increase accuracy, and improve production throughput. The technology is superior compared to the limitations of traditional ADC technologies such as barcode technology.

Barcode and vision systems rely on optics and require a relatively clean and moisture–free environment. Touch memory does not use optics but does require a relatively clean environment because contact must be made to read the tag.

Can I use bulk RFID Tags purchased for multiple contracts?
Answer; Yes. RFID Tags are just limited to Cage Code and sequence number. You must ship the RFID on contracts with the same Cage Code and you may never duplicate a serial/sequence number.
