How RFID technology is favored by digital smart laboratories

                             The development of digital recognition technology

Today, a large number of digital identification cards such as credit cards, telephone cards, and financial IC cards are closely related to people's daily lives, and their applications make various transactions more convenient and faster. However, most of these identification cards use magnetic stripe swiping cards or IC chips to make a contact connection with a card reader to read data information. In long-term use, it is easy to cause data identification errors due to wear and tear, and the contact identification card has a specific contact point, the card has directionality, and the convenience of operation needs to be improved.


In the 1990s, in response to the shortcomings of the contact identification system, an automatic identification technology, radio frequency identification (RFID), was gradually developed and gradually matured. It uses radio frequency for non-contact two-way communication to achieve the purpose of identifying and exchanging data.

                                   RFID technical attributes

The most basic RFID system consists of three parts: electronic tags, readers, and antennas. The tag is composed of a coupling element and a chip. The tag has a built-in antenna for communication with the radio frequency antenna; the reader is used to read or write tag information; the antenna is used to transmit radio frequency signals between the tag and the reader.

Since each electronic tag has a globally unique ID number-UID (UID is placed in the ROM when the chip is made, and cannot be modified or imitated), the data part can be securely managed by some encryption algorithms, readers and tags Mutual security authentication process can be set up between. Therefore, RFID technology has achieved rapid development in anti-counterfeiting and other applications, and has achieved certain breakthroughs.


At present, RFID tags can be embedded in standard passport covers or documents in terms of passport anti-counterfeiting and electronic wallets. The chip also provides security functions and supports hardware encryption to ensure security. A considerable scale of applications has also been formed in this field in China, and the new era ID cards are being promoted and applied accordingly.

                                      Advantages of RFID technology

In the field of identification, traditional barcode technology is relatively mature and has been extremely widely used all over the world. As a means of computer data collection, bar code is widely used in various fields such as commodity circulation, automatic control, and file management with many advantages such as speed, accuracy, and low cost. It is also the most used data recognition method in my country. However, because the traditional barcode is one-dimensional, it does not carry any information in the vertical direction, has low information density, and is easily rejected due to wear or wrinkles, which largely limits the application range of traditional barcodes.

The emergence of RFID technology has changed the way that barcode technology relies on "tangible" one-dimensional or two-dimensional geometric patterns to provide simple information. RFID provides information with a larger amount of data through its own chip, and the introduction of RFID technology is not only as simple as the increase of information capacity. From the perspective of data encryption, information transmission methods, and processing efficiency and accuracy, RFID is computer automatic identification. A revolution in technology.

RFID technology can identify specific targets and read and write related data through radio signals, without the need to establish mechanical or optical contact between the identification system and specific targets. It automatically recognizes the target object and obtains relevant data through radio frequency signals. The recognition work does not require manual intervention. It can recognize high-speed moving objects and can recognize multiple tags at the same time, which is quick and convenient. It is widely used in logistics management, transportation, medical and health, commodity anti-counterfeiting, safety protection, management and data statistics and other fields. It is recognized as one of the top ten important technologies in the 21st century. It has the following advantages: it can identify the hazardous chemicals of different RFID tags within a certain distance in a non-contact manner; it can identify multiple tags at the same time and realize synchronous communication. Therefore, in the field of digital smart laboratory construction, RFID technology is also widely used in label identification of laboratory reagents to achieve the role of safety management.

RFID is easy to control and non-contact automatic identification characteristics, suitable for automatic control and harsh environment multi-target recognition, moving target recognition and other applications. And because the technology is difficult to be counterfeited or intruded, it has high security protection capabilities, and it is also used in the field of authenticity identification.
