RFID is a non-contact automatic identification technology, which automatically identifies target objects and obtains relevant data through radio frequency signals. Because the RFID tag communicates with the reader in a contactless way, there is a spatial wireless channel.
If we want to achieve secure, reliable, and effective data communication, RF tags and readers must abide by the mutually agreed communication protocols. Otherwise, they will not understand what the other side says, and will not be able to keep pace with each other, thus making the data communication impossible.
RFID standards and protocols are the basis of RFID chip design. At present, the common international RFID standards and protocols are ISO/IEC 18000, ISO11784, ISO11785, ISO/IEC 14443, ISO/IEC 15693, EPC Gen2, etc.
1、ISO/IEC 18000 Series
ISO/IEC 18000 series standards are most eye-catching among RFID wireless interface standards, which cover the communication frequency from 125 kHz to 2.45GHz, with reading distances ranging from a few centimeters to dozens of meters, mainly passive tags but also active tags for containers. There are seven standards with the ISO 18000 series as follows:
- 18000–1: Generic parameters for air interfaces for globally accepted frequencies
- 18000–2: Air interface for 135 kHz
- 18000–3: Air interface for 13.56 MHz
- 18000–4: Air interface for 2.45 GHz
- 18000–5: Air interface for 5.8 GHz
- 18000–6: Air interface for 860 MHz to 930 MHz
- 18000–7: Air interface at 433.92 MHz
2、ISO 11784/11785 (134.2 kHz)
ISO 11784 and ISO 11785 are international standards that regulate the RFID of animals, which is usually accomplished by implanting, introducing, or attaching a transponder containing a microchip to an animal.
ISO 11784- Code Structure
ISO 11784 specifies the structure of the identification code, including transponder data transmission method and reader specification, working on 134.2 kHz.
ISO 11785- Technical Standard
ISO 11785 specifies how a transponder is activated and how the stored information is transferred to a transceiver.
RFID tags from different manufacturers can be read using a common reader according to this standard. Besides, transponder size is not specified in the standard, so it can be designed in a variety of shapes to suit different animals, such as glass tubes, earmarks, or collars.
3、ISO/IEC 14443 (13.56 MHz)
ISO/IEC 14443 is one of a series of International Standards describing the parameters for identification cards as defined in ISO 7810 and the use of such cards for international interchange.
ISO/IEC14443 protocol is divided into two types: TypeA & TypeB, both operating at 13.56 MHz (RFID HF). They are close-reading protocols. Label read-write distance is 0~10cm. The main difference between A and B lies in their modulation, coding schemes, and anti-collision methods.
Strong anti-interference ability but poor power stability, mainly used in the field of transportation, urban construction access cards, bus cards, and small stored value consumption cards, with a high market share.
Good stability, high security, but relatively vulnerable to external environment interference. Because the encryption coefficient is relatively high, it is more suitable for CPU card, generally used for ID card, passport, bank card, etc.
4、ISO/IEC 15693(13.56 MHz)
ISO/IEC 15693 is a long-distance reading protocol and also a popular HF (13.56 MHz) standard for High RFIDs widely used for non-contact smart payment and credit cards.
It is compatible with ISO 18000-3 and allows long-distance communication. The maximum reading distance is 100mm, and the application is more flexible. It widely used in production automation, medical management, jewelry inventory, asset management, parking management and product anti-counterfeiting, access control, asset management, logistics & supply chain, library management, etc.
5、EPC Gen2 (860~960 MHz)
EPC Gen2 is the second generation standard of the Class1UHF RFID air interface developed by EPCglobal. The standard is similar to ISO18000-6. EPC Gen2 was approved by ISO in 2006 and incorporated into the ISO standard system known as ISO 18000-6C.
ISO 18000-6C (EPC Gen2) protocol is the most widely used protocol in medium and long-distance. Tags under the EPC Gen2 protocol can be read and written repeatedly, and have a good confidentiality performance.
