RFID Electronic tag technology, also known as RFID (Radio FrequencyIdentification), is a non-contact automatic identification technology. The information stored in the RFID electronic tag can be read by Radio waves emitted by sensors within a distance of a few centimeters to a few meters. Identify the identity of items, people and appliances represented by RFID electronic tags.
RFID electronic tag technology and other automatic identification technology, such as compared with bar code identification technology, has the following characteristics: RFID electronic tag reader through mud, dirt, oil, wood, cement, plastic, steam and other non-metallic materials to read the tag, not necessarily direct contact with the tag; RFID electronic label data storage capacity is large, the label data can be encrypted, updated at any time;
RFID electronic tags achieve "contactless", do not need linear scanning operation, fast reading and writing speed, reading distance is large; RFID electronic tags are small in size, easy to package and diverse in shape. RFID electronic tag service life can be more than 10 years, read and write 100,000 times, no mechanical wear, no mechanical failure; RFID electronic tags are unique in number and can be added with security identification codes.
RFID performance characteristics:
1. Quick scan.
RFID reader can identify and read several RFID tags at the same time.
2. Miniaturization and diversification of shape.
RFID is not limited by size and shape in reading, and does not need to match the fixed size and printing quality of paper for reading accuracy. In addition, RFID tags can be miniaturized and diversified forms of development, to be applied to different products.
3. Pollution resistance and durability.
While traditional barcodes are based on paper, which makes them vulnerable to contamination, RFID is highly resistant to substances such as water, oil and chemicals. In addition, as bar codes are attached to plastic bags or outer cartons, they are particularly vulnerable to damage; RFID labels store data in chips, so they can be protected from contamination.
4. Reusable.
Today's bar code can not be changed after printing, RFID tags can be repeated to add, modify, delete the data stored in THE RFID volume label, convenient information update.
5. Penetrative and unobstructed reading.
When covered, RFID is able to penetrate non-metallic or opaque materials such as paper, wood and plastic, and is capable of penetrating communication. The bar code scanner must be at close range and free of objects to read the bar code.
6. Large memory capacity of data.
A one-dimensional bar code has a capacity of 50Bytes, a two-dimensional bar code has a maximum capacity of 2 to 3000 characters, and an RFID has a maximum capacity of several MegaBytes. With the development of memory carrier, data capacity is also increasing. In the future, the amount of data that objects will need to carry will increase, and the need to expand the capacity of labels will increase accordingly.
7. Security.
Because RFID carries electronic information, its data content can be protected by password, so that its content is not easy to be forged and altered.
RFID has attracted much attention because of its features such as remote reading and high storage capacity. It can not only help an enterprise greatly improve the efficiency of goods and information management, but also enable sales enterprises and manufacturing enterprises to connect, so as to receive feedback information more accurately, control demand information and optimize the whole supply chain.
NFC (Near field wireless communication technology) is developed on the basis of RFID. NFC is not much different from RFID in essence, which is based on the transmission of signals between two objects in close geographical locations.
However, there are differences between NFC and RFID.
NFC technology adds point-to-point communication function, which can quickly establish P2P (point-to-point) wireless communication between Bluetooth devices. NFC devices find each other and establish communication connections. The two devices of P2P communication are peer, while the two devices of RFID communication are master-slave.
There are other technical details:
Compared with RFID technology, NFC has some characteristics such as short distance, high bandwidth and low energy consumption. Details:
1. NFC is only limited to 13.56MHz band! RFID has low frequency (125KHz to 135KHz), high frequency (13.56mhz) and uHF (860MHz to 960MHz).
2. Working effective distance: NFC (less than 10cm, so has a high security), RFID distance from a few meters to dozens of meters!
3. Because also works at 13.56MHz, NFC is compatible with the existing contactless smart card technology, so many manufacturers and related groups support NFC, while RFID standards are more, more complex unified (estimated is not possible to unify), can only be in a special industry with special needs, the corresponding technical standards!
4. Application: RFID is more applied in production, logistics, tracking, asset management, while NFC plays a huge role in access control, public transportation, mobile payment and other fields.
Differences between NFC and RFID:
1. NFC integrates contactless card reader, contactless card and point-to-point function into a single chip, while RFID must be composed of reader and tag.
RFID can only realize information reading and judgment, while NFC technology emphasizes information interaction. Informally, NFC is an evolution of RFID, where the two parties can exchange information in close proximity. NFC mobile phone built-in NFC chip, constitute a part of the RFID module, can be used as RFID passive tag for payment; It can also be used as RFID reader for data exchange and collection, and can also be used for data communication between NFC mobile phones.
2. The transmission range of NFC is smaller than that of RFID. The transmission range of RFID can reach several meters or even tens of meters.
3. Different directions of application. While NFC looks more at consumer electronics devices communicating with each other, active RFID is better at identifying them over long distances.
With the popularity of the Internet, mobile intelligent terminal as the Internet the most direct, will cause a technological revolution, such as bluetooth, USB, GPS standard, NFC will become the most important standard, the mobile phone in the future through the NFC technology, mobile payment, watch movies, take the subway can be implemented, will be in our daily life play a more important role.
Printing method of RFID/NFC electronic tag Antenna PCB:
RFID electronic tag antenna manufacturing commonly used technical methods are: Etching, Electroplating and Direct Printing (conductive ink printing Brush method), all belong to the antenna printing technology. At present, etching and electroplating are the main methods at home and abroad, and direct printing is a newly emerging and studied printing technology.
1). Etching method. Also known as printing etching, or reduced to printing.
First in a base carrier (such as plastic) covered with a layer of 20um ~ 25um thick copper or aluminum, in addition to the production of an antenna positive screen printing plate, with the screen printing method will be printed on the surface of the corrosion inhibitor of copper or aluminum, protect the following copper or aluminum erosion; The copper or aluminum that is not covered by the corrosion inhibitor will be dissolved by the corrosion agent, exposing the base to become the spacing line of the antenna electrical route; Finally, the anti-corrosion film is removed with the coating solution, and then the antenna is made.
2). Electroplating method. Also known as printing and electroplating, or addition printing.
The substrate is coated by printing with a thin layer of catalytic ink (a few microns) in the shape of a positive antenna. The special ink contains metal particles. After printing, the printed material goes through an electroplating process in which copper is coated on the material and only attaches to the pattern formed by the ink. The electroplating process continues until the amount of copper deposited on the material is thick enough to make it conductive enough to form the antenna.
3). Direct printing method.
Direct printing method is to directly use conductive ink on the insulating base (film, paper, etc.) to print conductive lines, forming antennas and circuits. The reason why the RFID electronic tag antenna printed by direct printing method is stronger than the RFID electronic tag antenna made by traditional method
The characteristics and advantages of the line, mainly depends on the characteristics of conductive ink and the perfect combination of printing technology.
Conductive ink, also known as conductive adhesive, conductive silver paste, is a special ink that allows current to flow, composed of dispersed fine conductive particles and conductive polymers. Printing on flexible or hard substrates can be made into printed circuit, play the role of wire, antenna and resistance, to a large extent determines the RFID printing antenna impedance, which is an important parameter related to the performance of RFID antenna.
