RFID UHF Chip and Application

RFID UHF chips, generally, are based on ISO18000-6C standard.
UHF frequencies guarantees reading distances up to 10meters and chips, generally, have a EPC memory (modifiable tag code), a TID memory (transponder Identifier) and different size user memory .

We propose below some UHF chips:

Alien Higgs3: Chip of interesting features, both for user memory size (512bit) and for high performance as reading distance.

Alien Higgs4: Chip very intersting becuase of the cost, very low, and the performances, seriously improved, compared to Alien Higgs3. User memory is reduced to 128bit.

NXP UCODE7: Without user memory and with 128bit EPC memory is a very simple and low-cost chip.

NXP UCODE DNA: Chip based on GS1 Gen2 V2 standard with encryption, it is untraceable with a 3072bit user memory.

APPLICATIONS WHERE CHIPS UHF ARE USED
* Access Control
* Inventory
* Job Security
* Timing of sport races
* Asset Management
* Waste Management

What does an RFID inlay consist of?

Functionally, an RFID inlay consists of an antenna and a microchip.

The antenna drives tag performance and governs how well the tag will work in a particular application. Precision-designed to receive and broadcast RF signals, the antenna is made from a conductive material (such as silver, copper or aluminum), with each material producing very specific read and write characteristics because of the different chemical properties. Generally a copper antenna is slightly more expensive that aluminum or silver, but is more conductive and usually provides a longer distance read capability.

The antenna makes contact with an RF reader over a distance, which is determined in large part by the amount of metal, and by the size and shape of the antenna. Contacts attached to the microchip make the circuit between the microchip and antenna.

The microchip design determines the protocol and class of the tag's operation. Different microchips have different features that can also affect performance. RFID microchips contain circuitry capable of handling a variety of functions from power conversion to data storage and retrieval.

RFID Tag Attachment

When RFID tags are thought of, adhesion is thought of because specialized, permanent pressure sensitive adhesives RFID tags are used prolifically to attach adhesive-backed tags to assets. Some adhesives will withstand a great deal of pull pressure even in extreme environments, while others will release more easily. The pull strength selected will depend upon the intended use of the asset and its potential lifespan. Some adhesives are applied to tamper-evident tags to leave an unremovable adhesive imprint if the tag is removed.

RFID tags are attached to assets in other ways too. Many hard tags, especially those used with active RFID tags, are attached with metal fasteners such as screws. Button tags used in laundry venues as well as others places can be glued, but also sewn,heat-sealed or tied. Die cut tags with circular holes allow hang tags to dangle from lanyards, cords, cables, and zip ties. Popular fob tags swing from key chains. Die cut RFID hang tags can also be cut to form a hang hook in the tag itself, thus enabling the tag to hang itself.

What are the key component of RFID tags

Of the three components of an RFID network, the label, which is attached to the object to be identified, is central. The labels usually are made of a substrate encasing a microchip/antenna inlay; together latter is called a tag. The labels are attached to objects as hanging labels or as flat labels applied directly to the object.

The microchip mounted on an integrated circuit is the heart of the label. This microchip contains encrypted information including the unique identification number and location of the object along with whatever other information the label buyer desires. Additionally, a programmer configures the microchip to contain the commands that control the operation of the chip itself including its operation as a passive or active tag and operational frequencies.

The chip and the circuit are mounted on a wafer of silicon. Usually a tiny antenna for transmission of information is robotically soldered to the circuit to complete the inlay, but, in some applications, the antenna is printed with metallic ink on a thin substrate and placed over the circuit to make a connection. Subsequently, the inlay, the functional portion of the RFID label, is supplied on a substrate as a dry inlay, or if adhesive is added, a wet inlay to a label manufacturer called a converter.

Around the inlay, converters form a sturdy RFID label.
Using a converter machine, the final form of the label takes shape. The inlay is encased in substrates made of different polymers for specific applications. Some RFID tags must withstand high temperatures, some must be resistant to abrasion, some must be water proof and so forth. Some must have color and holographics combining eye candy and functionality for pleasurable events like concerts. The label, too, might be embed with a strong adhesive on the reverse of the tag to adhere to a customer’s assets.
Often, these adhesives have tamper-evident properties. For two tracking technologies, an additional plus on some labels is the ability to add customer programming that can be matched to printed barcode information.

After fabrication, the multiple labels on the sheet of composite substrates must be separated. As the composite passes through the press-like machine, its dies, lasers or razors are capable of cutting many different shapes to meet customer demand and object requirements.
