RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require human intervention and can work in various harsh environments.
RFID technology can identify high-speed moving objects and can recognize multiple RFID labels at the same time, and the operation is fast and convenient. RFID is a simple wireless system, consisting of only two basic device readers and RFID tags, and is usually used to control, detect, and track objects.
RFID tags are classified according to modulation methods, which can be divided into active tags and passive tags. Active tags use their own radio frequency energy to actively send data to the reader, which is mainly used in applications with obstacles; passive RFID tags use modulation and scattering to transmit data, and it must use the carrier of the reader to modulate its own signal. It is suitable for access control or traffic applications.
Available Blank Passive RFID Tag Chips
Low Frequency RFID Chip
The common main frequency is 125KHz. Generally, RFID labels in this frequency band are passive, and provide energy supply and data transmission through inductive coupling. The biggest advantage of the low-frequency RFID chip is that the tag is less affected when the tag is close to metal or liquid items. At the same time, the low-frequency system is very mature and the price of the reading and writing device is low.
But the disadvantages are the short reading distance, the inability to read multiple tags at the same time (anti-collision), and the low amount of information. The storage capacity of general chips is from 128 bits to 512 bits. Mainly used in access control systems, animal chips, car alarms, and toys.
Although the low-frequency system is mature and the price of reading and writing equipment is low, due to its low resonance frequency, the tag needs to make a winding inductor with a large inductance value, and often requires an off-chip resonance capacitor. In fact, the cost of the tag is higher than the other frequency.
High Frequency RFID Chip
The common frequency is the 13.56MHz ISM band. The RFID label in this band is still passive, and it also uses inductive coupling for energy supply and data transmission.
The biggest application of RFID chips in this frequency band is the contactless smart cards we are familiar with.
Compared with low frequency, its transmission speed is faster, usually above 100kbps, and it can be identified by multiple tags (each international standard has a mature anti-collision mechanism). The system in this frequency band benefits from the application and popularity of contactless smart cards. The system is also relatively mature, and the price of reading and writing equipment is relatively low.
High-frequency RFID chip products are the most abundant, with storage capacity from 128 bits to more than 8K bytes, and can support high security features, from the simplest write lock, to stream encryption, and even encryption coprocessors are integrated . Generally used in identity recognition, library management, product management, etc. RFID applications that require high security, this band is currently the only option.
Ultra High Frequency
The common main frequency is 860~960MHz. The RFID label in this frequency band transmits energy and information through electromagnetic waves.
Both active and passive applications are common in this frequency band. Passive tags have a reading distance of about 3 ~ 10 m. The transmission rate is relatively fast, and can generally reach about 100kbps. And because the antenna can be manufactured by etching or printing, the cost relatively low.
Because the reading distance is far away, the information transmission rate is fast, and a large number of tags can be read and identified at the same time, it is especially suitable for logistics and supply chain management. However, the disadvantage of this frequency band is that it is less ideal for metal and liquid objects, and the system is not yet mature, the price of reading and writing equipment is very expensive, and the cost of application and maintenance is also very high.
In addition, the safety characteristics of this frequency band are general, and it is not suitable for application fields with high safety requirements.
