Access control card (ID card, IC card, CPU card) how to distinguish the identification?

Access card (ID card, IC card, CPU card) how to distinguish identification?

 ID card cards have 10 digits in front of the card, or 8 digits behind. White square cards and key fob cards are distinguished in this way.

ID cards, which cannot be encrypted, can be easily copied, but not mobile NFC. Because the ID working frequency is 125KHz, and cell phone NFC and IC card reader working frequency is 13. 56MHz, so cell phone NFC and IC card reader can not read out ID must use the card ID card reader.

 IC card is blank before and after, there is no number. White square cards and key fob cards are distinguished in this way.

IC card, can be encrypted, not encrypted, but in actual use, not encrypted.

Unencrypted can be easily copied, and Android phones can be easily simulated

Can also be copied encrypted, but need to be cracked with a tool.

 CPU card: non-replicable card.

Use it honestly and without any illusions. This type of card is usually associated with money transactions or identification (e.g. ID cards) and there is no replication technology available.

How do I read an encrypted card?

Copying ID cards

Since ID works at 125KHz and cell phone NFC works at 13. 56MHz, cell phone NFC cannot read ID must use card ID only card reader to copy it.

Copy unencrypted card

Unencrypted IC card, you can easily use the cell phone NFC copy function, see my article access control card how to get the phone, the phone into access control card, handy super detailed.

 Copy encrypted IC card

Tools: cell phone NFC can not read the encrypted data of IC cards need some tools, such as CD100, icopy8. cloud rhinoceros decoder, PN532, ACR122U, Proxmark and so on; the first two are also called fool machines, locksmiths use more, the latter few are mostly used by practitioners and enthusiasts.

Method: You need to simulate a blank card first, and then use a machine that can crack the duplicate card such as Cloud Stream decoding. First crack and copy the original card data, and then write the blank card simulated by the phone. This process requires the use of two cell phones at the same time.

The easiest way: buy a slim cell phone IC card sticker, about 5 yuan a card, use the card writer to copy the original card directly into the card sticker, the new card is attached to the back of the phone, and do not need to take the key fob.

3, a detailed description of ID cards, IC cards, CPU cards

? ID card-phase out

Two minutes to understand, a variety of access control cards (ID card, IC card, CPU free copy card)

ID card

Professional version of the explanation

ID card: full name identification card (Identification Card), low frequency (frequency 125Khz, 250 Khz, 375 Khz, 500 Khz, etc.).

Can not write the induction card, including fixed number, factory solidified ID.

Common version explanation

ID card only reads the card, can not be stored or encrypted, but the factory number has been cured. Currently using ID most cards are old neighborhoods, parking lots of low importance.

For example, the name of the system file in the Windows installation directory of the computer operating system (analogous) UID) it has been generated, can not change the file name or file content, but it is easy to copy.

 IC card - widely used

Two minutes to understand, a variety of access control cards (ID card, IC card, CPU free copy card)

IC card

Professional version of the explanation

IC card: the full name of the integrated circuit card (Integrated Circuit Card), also known as smart card (Smart Card).

A card system, consumer systems, etc. can read and write data, large capacity, strong encryption function, reliable data records, easy to use.

Explanation of common version

IC card chip, readable, writable and encrypted. Widely used in schools, canteens, access control, hotels, etc.

For example: just like a new word in the computer can be read, write, rename, encrypted and other documents, such as setting the document password.

Others copy the past can not see what is inside. Unless using tools.

? CPU card-plus the highest density card

Professional version explanation

CPU card is also called smart card, the integrated circuit inside the card has microprocessor CPU, storage unit (including random memory) RAM, program memory ROM (FLASH), user data memory EEPROM) and chip operating system COS.

The card is equivalent to a microcomputer with a COS CPU, which not only has data storage functions, but also has command processing and data security protection functions.

Common explanation

The CPU card has a high degree of confidentiality.

Example: CPU card is like a computer, it is almost impossible to copy a computer with the same data exactly.
