In addition to the common tags used in retail, UHF RFID labels can be used for tracking products that have been shipped. Because RFID tags are read inside boxes, cartons, and cases, it is possible to read hundreds of them at a time. These tags are also incredibly versatile. They can be read even if the packaging is made of plastic or metal. As long as the packaging is properly labeled, the labels can be read from hundreds of feet away.
Active
An Active UHF RFID label has the capability to read and write data on materials and items. It can also be used to track assets. Active tags are typically used for high-value assets like gold. Passive tags are most commonly used for pallet labels and product labels. Both labels and tags are components of an RFID system, which includes antennae, readers, and a processing system. A label converter is used to make these components work together.
RFID tags can be used to track various kinds of objects, including assets and inventory. These tags can be used in healthcare, retail, manufacturing, and manufacturing environments. Depending on their purpose, they can range from a few centimeters to a few meters. However, their functions vary greatly. Before deciding on the right type for your business, it’s best to get advice from a label converter with experience delivering tags for various business uses.
Passive
A passive UHF RFID label is a radio-frequency identification tag that works over a frequency range of 902MHz to 928MHz for North America, and 865MHz to 868MHz for Europe. This type of tag has a number of unique features, including built-in application-specific security, a low turn-on threshold, a high receive signal sensitivity, and a password-controlled read.
The basic structure of a passive RFID tag consists of an integrated circuit and an antenna. The IC is powered by radio waves from the reader. Because passive tags do not need an external power source, they are often small and inexpensive. Another benefit of passive RFID is that they can operate in harsh environments. In most cases, they can operate for decades without requiring an external reader. But if you need a high-speed, highly accurate tracking, or multiple-address identification, an active UHF RFID tag is right for you.
On-metal
An On-metal UHF RFID label is an excellent choice for many industrial applications, including packaging that holds liquids. This type of label is highly durable and offers several benefits. It is inexpensive, and can be printed with information directly on its surface. Because the RFID tag can be printed directly on metal, it is the most ideal solution for many types of traceability applications. Its use in automotive and industrial settings, for example, makes it an excellent choice for tracking metal bins during production.
The On-metal UHF RFID label is EPC C2 Gen2-compliant, and has a read range of four meters on metal. This tag is also weather and chemical-resistant, with a high-tack adhesive. It can withstand industrial washing with standard solvents, but it should be tested before being placed on assets. Once installed, an On-metal UHF RFID tag will ensure reliable and safe asset tagging.
UV resistance
UV resistance on UHF RFID Label for outdoor use. This type of label is able to withstand direct sunlight, and needs to be protected from other forms of light. Some RFID tags are ATEX certified for use in areas with hazardous atmospheres, like mines and other places with flammable gases. These tags must be resistant to UV light exposure, and must be installed in an appropriate location in order to work properly.
Hard tags can also be tough, but not all RFID tags are made of the same material. Hard tags are more durable because they can withstand shocks and vibration. Some tags are prone to breakage in high-impact environments, such as vehicles or trains. Therefore, it is important to find a hard tag that is designed to withstand high-temperature environments. RFID hard tags are usually more expensive than labels. Depending on their purpose, they can be made of several materials, including polycarbonate, ceramic, ABS, steel, and polypropylene.
Tag chip
To measure the read range of an RFID tag, we have first developed a flexible substrate with an ultra-high-frequency RFID tag chip. In this work, we have fully fabricated a flexible RFID tag with an array of printed components. The tag antenna is inkjet-printed and the layout is sprayed-deposited. Our prototype RFID tag is capable of reading data from a wide variety of objects, from tags in supermarkets to medical equipment.
Our low-cost UHF RFID tag chip incorporates an advanced encryption standard, AES, for security. The digital baseband design was verified on the Field-Programmable-Gate Array (FPGA) platform. The chip also contains an analog and radio frequency frontend, an EEPROM, and an electrically eraseable RAM (EEPROM). The chip measures only 0.6×0.3 mm2 and consumes 20.9 uW.
