Smart Card Protocol Standard

Commonly used international RFID protocol standards corresponding to common frequencies

      The communication standard of the radio frequency tag is the basis for the design of the tag chip. The current international communication standards related to RFID mainly include: ISO/IEC18000 standard (including 7 parts, involving 125KHz, 13.56MHz, 433MHz, 860-960MHz, 2.45GHz and other frequency bands) ), ISO11785 (low frequency), ISO/IEC14443 standard (13.56MHz), ISO/IEC15693 standard (13.56MHz), EPC standard (including Class0, Class1 and GEN2 and other three protocols, involving HF and UHF two frequency bands), DSRC standard (European ETC standard, including 5.8GHz).

Now do a brief introduction to some commonly used standards according to frequency (and also introduce the protocol standards of contact IC cards):

1. ISO7816: Some specifications for contact IC cards.

Contact IC card is divided into logical encryption card and memory card (non-encrypted card) and contact CPU card:

A: Logical encryption card: it can encrypt the memory card, you can modify the corresponding byte of the chip to obtain a new password, such as AT88SC102 (1K bytes), AT88SC1608 (2KB), SLE4404 (13B), SLE4406 (13B), compatible with FM4406) , SLE5542 (256B), SLE5528 (1KB), FM4428 (1KB), FM4442 (256B), etc. The initial password of SLE5542 is 6 F, and the initial password of SLE5528 is 4 F.

B: Non-encrypted card: also called data card, such as: AT24C01A, AT24C02, AT24C04, AT24C08, AT24C16, AT24C32, AT24C64, AT24C128, AT24C256, AT45D041, etc., among which AT45D041 is a large-capacity memory card with a storage capacity of 4M bits. (Note: There are domestic chips that can basically replace the above chips and are fully compatible. To distinguish from the appearance, the imported surface has an ATM mark.)

C: Contact CPU card: TG56, TG97, TG132, etc.

2. 125KHz~135KHz: ISO18000-2, some specifications for low-frequency identification RFID.

For example:

EM4100 and TK4100: are read-only low-frequency chips.

EM4469/4569: 11 blocks, 44 bytes, 512bit storage space. EM4205/4305: 16 sectors, 64 bytes (512bit).

ATA5567/5577: 7 blocks, 28 bytes, 330bit storage space, of which 224bit is user storage space and 96bit is system storage space. ATA5567 is an upgraded product of e5550, e5551, e5554, and T5557. e5550, e5551,

e5554 and T5557 are chips produced by German TEMIC company. In 1998, American Deatmel Company (referred to as ATMTL) acquired German TEMIC company. ATA5567 is a new chip produced by ATMEL.

3. 134.2KHz: ISO11784 and ISO11785, some specifications for animal identification RFID. For example:

EM4005, EM4105: The appearance of low-frequency tags applied to animal identification includes collar type, ear tag type, injection type, pill type, etc. Typical application animals are cattle, homing pigeons, etc.

HITAG ™2: It is often called HITAG2 internationally, and it is produced by Nhuipu, the Netherlands.

HIAG™ S256: It is often called HITAGA S 256 in China.

HITAGA™S 2048: It is often called HITAG S 2048 in China.

[Note 1: The predecessor of NXP Semiconductors in the Netherlands is PHILIPS Semiconductors. ]

[Note 2: HITAG™1, often called HITAGA 1 in China, is a composite of HITAGA 1 protocol, but it does not comply with the ISO11784/11785 protocol. ]

4. 13.56MHz: ISO 14443Type A&B, ISO 15693, ISO 18000-3 Mode 1&2, ISO18092 NFC, EPC HF CLASS 1, EPC HF Vwrsion 2

① A simple comparison between the ISO 14443 typeA and typeB protocol standards.

The international standard ISO14443 defines two signal excuses: typeA and typeB. ISO14443A and B are not compatible.

A. ISO 14443 Type A (also known as ISO 14443A) is generally used for access control cards, bus cards and small-value stored-value consumer cards, etc., and has a high market share.

        For example:

     MIFARE ULtralight (MFO ICU1X): It is often called U10 in China. This chip has no encryption function and can only be encrypted by the system. The memory is 64 bytes. Typical application: Guangzhou-Shenzhen high-speed train ticket. (Another: MIFARE ULtralight C, also called U20, this chip can be encrypted, the memory is 192 bytes). The number of internal code numbers of these two chips are the same, but the internal code data is different. (Domestic compatible chips have 64 bytes of FM11RF005 memory, 64 bytes of BL75R12 memory, etc.) 

 MIFARE Std 1k (MF1 IC S50): It is often called MF1 S50 in China. Mainly used in a card. The memory is 1KB, with 16 sectors, each sector has 4 blocks, and each block has 16 bytes. The initial password is 12 F. (Domestic compatible chips are FM11R08, ISSI4439, TKS50, BL75R06, etc.)

     MIFARE Std 4k (MF1 IC S70): It is often called MF1 S70 in China. Mainly used in a card. The memory is 4KB, with a total of 40 sectors. The first 32 sectors are the same as S50, each sector has 4 blocks, and the last 8 sectors are 16 blocks, and each block is 16 bytes. The initial password is 12 F. (Domestic compatible chips are ISSI4469, FM11RF32 and BGI's S70)

     Mifare DESFire 4k (MF3 IC D41/D40): It is often called MF3 in China. Typical application: Nanjing Metro.

     SHC1102: Produced by Shanghai Huahong. Typical application: Shanghai All-in-One Card.

B. ISO14443B is more suitable for CPU cards due to its relatively high encryption coefficient, generally used for ID cards, passports,

For UnionPay cards, etc., the current second-generation electronic ID card adopts the ISO 14443 TYPE B protocol.

For example:

       SR176: produced by Swiss STMicroelectronics (ST).

       SRIX4K: produced by Swiss STMicroelectronics (ST).

      THR1064: Produced by Beijing Tongfang. Typical application: Olympic tickets.

      AT88RF020: American Atmel (ATMIL) production. Typical application: Guangzhou Metro Card.

      Second-generation resident ID cards: produced by Shanghai Huahong, Beijing Tongfang THR9904, Tianjin Datang and Beijing Huada.

  ②, ISO 15693 agreement

      The reading and writing distance of ISO 14443A/B is usually within 10cm, which is widely used. However, the reading and writing distance of ISO15693 can reach 1m, the application is more flexible, and it is compatible with ISO 18000-3 (many of our national standards are compatible with most of ISO 18000).

For example:

ICODE SLI (SL2ICS20): It is often called ICODE 2 in China (the memory is 1Kbit), and this model is commonly used. Domestically compatible are BL75R05 and FM1302N. (Also: ICODE SLI-S memory is 2048bit, ICODE SLI-L memory is 512bit, these two chips are not commonly used in China.)

   [Remarks: ICODE 1 (SL2 ICS30), often called ICODE 1 in China, conforms to the ICDEI protocol, but does not comply with the ISO 15693 protocol. ]

Tag-it HF-1 Plus: It is often called Tl2048 in China, produced by Texas Instruments (TI).

EM4135: EM produced in Switzerland.

BL75R04: produced by Shanghai Belling and FM1302T (produced by Fudan University), compatible with TI's Tag-it HF-1 Plus.

③, ISO 18092NFC: Some specifications for short-range wireless communication technology.

5. 433.92MHz: ISO 18000-7

   Equipped with corresponding readers, the reading distance is far.

6. 860~960MHz: ISO18000-6 Type A&B&C, EPC UHF Class 0&1, EPC Class I Generation2

  Equipped with corresponding readers, the reading distance is generally greater than 1m, typically 4-6m, and the maximum can reach more than 10m.

  At the current level of technology, the relatively successful product pairs of passive microwave radio frequency tags are concentrated in the 902~928MHz working frequency band

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 ICS10): It is often called GEN2 in China, which conforms to ISO18000-6Type C protocol.

  RI-UHF-OOC02-03: Produced by Texas Instruments (TI for short), conforming to ISO 18000-6-Type C protocol.

7. 2.45GHz: ISO 18000-4 Mode 1&2

   The reading distance of a typical microwave radio frequency tag is 3~5m, and some products can reach 10m or more.
