RFID is a type of tracking system that uses radio frequencies to find, identify, track, and communicate with an item or person. RFID tags are essentially smart labels that can store a variety of information ranging from serial numbers to short descriptions and even pages of data. Cryptographic security features are built into some RFID tags for high-level authentication and identity verification. RFID tags are typically identified by their radio frequency, which can be low frequency (LF), high frequency (HF), or ultra-high frequency (UHF) (UHF).OSRFID focuses on the development and manufacture of HF and UHF tags.
1. Low frequency tags have a frequency range of 30 to 300 kHz and a reading range of up to 10 cm. These tags are more commonly used in access control and livestock monitoring applications.
2. High frequency tags have a read range of 3 to 30 MHz and a read range of 10 cm to 1 m. (3 ft). These tags are commonly used in applications such as electronic ticketing, payment, and user experience.
3. UHF tags are available in frequency ranges ranging from 300MHz to 3GHz, with read ranges of up to 12m (39ft). The most common applications for these tags are retail inventory tracking, parking, access control, and asset management.
RFID tags are classified into three types based on whether or not they have a battery: active tags, passive tags, and semi-active tags.
1. Active RFID tags, which require their own transmitter and power supply, are less common. These tags are typically larger, more durable, and more expensive.
2. Semi-passive RFID tags are located directly between active and passive tags. The semi-passive tag functions exactly like the intermediate option and provides a number of features derived from the functionality of both active and passive tags. Semi-passive RFID tag characteristics include: Built-in battery, shorter read range than active tags but longer than passive tags. The dual frequency temperature sensing tags from OSRFID are semi-passive RFID tags.
3. The most common type of RFID tag is passive; it does not require a direct line of sight to the reader, but it has a shorter read range, is smaller in size, and weighs less. OSRFID is a Chinese RFID tag manufacturer specializing in passive RFID tags.
1. First, determine the application scene. If the tag is attached to metal, choose a tag that can withstand metal interference; if the tag is non-metal, a standard tag will suffice.
2. Second, choose the label based on the chip and antenna. Because different chip models and antennas are appropriate for use in various application scenarios. A specific chip and antenna combination can provide the best RFID performance. We recommend that you contact our RFID experts for advice on selecting a chip.
3. You will choose a few tags using the method described above. Finally, you’ll need to run performance tests on these tags to see which one performs best in practice. You can contact our sales staff to obtain a few samples of appropriate tags.
NFC is a subset of HF RFID technology that connects the Internet of Things (IoT) for more complex and secure interactions.
One of the primary distinctions between NFC and traditional HF RFID is that NFC readers can emulate RFID tags, allowing you to pay for goods using an NFC phone at a point of sale terminal. Whether near field communication is superior to traditional shortwave systems is entirely dependent on the application. As more mobile phones incorporate Near Field Communication, it is likely that this technology will dominate the mobile payment market and consumer applications, while traditional HF is used for access control, inventory management, and other applications.
Yes. We are a professional Chinese manufacturer with 20 years of RFID tag R&D and production experience.
Our headquarters are in Dongguan, Guangdong Province, China, and our factory is also there. In Shenzhen’s Longgang District, there are foreign trade firms.
Of course, you can. We have our own RFID technology R&D specialist on staff, as well as specialized R&D equipment. We can provide you with ODM and OEM services such as custom antennas, custom label styles, custom sizes, custom printing, and etc.
We use Chinese-made machines and imported machines to produce inlay and label at the same time to meet the needs of different products. The imported machines we use are: Mühlbauer DDA 40000 WF, Mühlbauer DDA 40000, and others.
