The communication standard of radio frequency tag is the basis of tag chip design. At present, the international communication standards related to RFID mainly include ISO/IEC 18000 standard (including 7 parts, involving 125 kHz, 13.56 MHz, 433 MHz, 860-960 MHz, 2.45 GHz and other frequency bands). Arsenic11785 (low frequency), ISO/IEC 14443 (13.56MHz), ISO/IEC 15693 (13)
A) ISO/IEC 14443 is close to the coupled IC card, and the maximum reading distance is 10cm.
The reader of ISO/IEC 14443 protocol has a short reading distance, basically a short distance. Among them,
ISO/IEC 14443A is mainly used in the fields of production automation, access control and attendance, security, all-in-one card and product anti-counterfeiting.
The main application of ISO/IEC 14443B in China is the second-generation ID card;
B) ISO/IEC 15693 loosely coupled IC card, maximum reading distance1m.
ISO/IEC 15693 protocol readers have a long reading distance and can communicate over a long distance.
It has a wide range of applications, including production automation, medical management, jewelry inventory, asset management, parking lot management and product anti-counterfeiting.
Access attendance, meeting attendance, barrier-free access, asset management, logistics supply chain, book management, medical management and ticket access.
Now briefly introduce some common standards by frequency (also introduce the protocol standards of contact IC cards):
1, ISO 78 16: Some specifications are made for contact IC cards.
2.125khz ~135khz: ISO18000-2, and made some specifications for low-frequency identification RFID.
For example:
EM4 100: read-only low-frequency chip.
Em4469/4569: 1 1 block, 44 bytes, 5 12 bit storage space.
Ata5567: 7 blocks, 28 bytes, 330-bit storage space. ATA5567 is an upgraded product of e5550, E55 1, e5554 and T5557. E5550, e555 1, e5554 and T5557 are chips produced by German TEMIC Company. 1998, American Termel Company (ATMTL for short) acquired German TEMIC Company, and ATA5567 is a new chip produced by ATMEL Company.
3.134.2khz: ISO11784 and ISO 1 1785, and made some specifications for animal identification RFID.
For example:
EM4005, EM4 105: The appearance of low-frequency tags used for animal identification includes collar type, ear tag type, injection type and pill type. Typical animals are cows, homing pigeons and so on.
HITAGTM 2: It is commonly called HITAG 2 in China and produced by NXP in the Netherlands.
HITAGTM S 256: It is commonly called HITAG S 256 in China.
HITAGTM S 2048: It is commonly called HITAG S 2048 in China.
[Note 1: NXP Semiconductors of the Netherlands was formerly Philips Semiconductors. ]
[Note 2: HITAG TM 1, commonly known as HITAG 1 in China, conforms to HITAG 1 protocol, but does not conform to ISO11784/1785 protocol. ]
4. 13.56 MHz: ISO 14443 A and ampISO 15693, ISO 18000-3/&; 2. ISO 18092 NFC, EPC HF Grade 1, EPC HF Version 2.
① ① A simple comparison between ISO14443a and B protocol standards.
The international standard ISO 14443 defines two signal interfaces: Type A and Type B.. ISO 14443A and b are incompatible.
A, ISO 14443A (also known as ISO 14443 A) is generally used for access cards, bus cards and small consumer cards, with a high market share.
For example:
Micare ultra-light (MF0 ICU 1x): it is often called U 10 in China. Typical application: Guangzhou-Shenzhen high-speed rail ticket.
Micare STD1k (MF1ics50): it is usually called MF 1 S50 in China.
SLE66R35 Mifare NRG: produced by Infineon Germany, compatible with mifare STD1K (MF1ICS50).
[Note 1: Infineon Technology Company, headquartered in Munich, Germany, is the largest manufacturer of semiconductor products in Germany. Its predecessor was the Semiconductor Department of Siemens Group, 1999 was independent and went public in 2000. Its Chinese name is Yiheng Technology, and it was renamed Infineon Technology after 2002. ]
Micare STD 4K (MF 1ICS70): It is usually called MF 1 S70 in China.
Mifare des Fire 4K (MF3 ICD41): It is often called MF3 in China. Typical application: Nanjing subway.
SHC 1 102: Made in Hua Hong. Typical application: Shanghai One Card.
B, ISO 14443B is more suitable for CPU cards because of its high encryption coefficient, and is generally used for ID cards, passports, UnionPay cards, etc. At present, the second generation electronic identity adopts ISO14443rd class protocol.
For example:
SR 176: Made in stmicroelectronics.
SRIX4K: made in stmicroelectronics (ST).
THR 1064: produced by Beijing Tongfang. Typical application: Olympic tickets.
AT88RF020: made in Termel, USA. Typical application: Guangzhou metro card.
Second-generation ID cards: produced by Shanghai Hua Hong, Beijing Tongfang THR9904, Tianjin Datang and Beijing Huada.
②ISO 15693 protocol.
The reading and writing distance of ISO 14443A/B is usually within 10cm, which is widely used. The reading and writing distance of ISO 15693 can reach 1m, which is flexible in application and compatible with ISO 18000-3 (many domestic national standards are compatible with most of ISO 18000).
For example:
ICODE SLI(SL2 ICS20): It is usually called ICODE 2 in China.
[Note: ICODE/KOOC-0/(SL2ICS30), commonly known as ICODE/KOOC-0/in China, conforms to ICDOE/KOOC-0/protocol, but not to ISO/KOOC-0/5693 protocol. ]
Tag-it HF- 1 Plus: It is often called TI 2048 in China, and it is produced by Dezhou Instrument Company (TI Company for short).
EM4 135: EM production in Switzerland.
BL75R04: produced in Shanghai Belling, compatible with the Tag-it HF- 1 Plus of TI Company.
③ISO 18092 NFC: standardization of near field communication technology.
5. 433.92 MHz: ISO 18000-7
Equipped with corresponding reader, reading distance is far.
6. 860 ~ 960 MHz:ISO 18000-6 A & AMPB &; C. EPC UHF level 0. 1 and EPC class 1 are equipped with corresponding readers, and the reading distance is generally greater than 1m, generally 4~6m, and the maximum reading distance is greater than 10m.
At present, the successful products of passive microwave radio frequency tags are relatively concentrated in the working frequency band of 902~928MHz.
For example:
UCODE HSL(SL3 ICS30): It is often called HSL in China, and conforms to ISO 18000-6 Type B protocol.
UCODE EPC G2(SL3 ICS 10): it is often called GEN2 in China, and conforms to the ISO 18000-6 Type C protocol.
RI-UHF-OOC02-03: Made by Texas Instruments (TI), conforming to ISO 18000-6 C class agreement.
7. 2.45GHz:ISO 18000-4 mode1&; 2
The reading distance of a typical microwave radio frequency tag is 3~5m, and some products reach 10m or more.
