Dc SmartCard, magnetic stripe card: A card-shaped magnetic recording media, and magnetic card reader used in conjunction. Card is the use of magnetic carriers with the digital information recorded in English, used to identify the identity card or other purposes. Depending on the use of the substrate is different from magnetic card can be divided into full-coated PET magnetic card, PVC magnetic cards and magnetic three kinds of paper; card easy to use, cost of cheap, extremely versatile, can be used to produce credit cards, bank cards, shopping cards, subway cards , query cards, membership cards, ticket cards, phone cards; tickets, air tickets, as well as account books. Key indicators: 1. Tak-shing, low-density magnetic stripe card: Anti-magnetic range of 250-340, or the range of 500-700 Oster Oster to meet the ISO7811 / 2 and national standards requirements, the customer may choose to apply their own magnetic Article. 2. Dc SmartCard, high-density magnetic stripe card: Anti-magnetic range of 2500-4000 Oster, in line with the standard ISO7811-6; 2750 Oster commonly used magnetic stripe, there are 4,000 Auster's high-density magnetic stripe. The higher the magnetic anti-magnetic resistance to accidental demagnetization of their greater ability, more reliability and stability, and many other advantages. Within the magnetic strip can be divided into three separate tracks, known as TK1, TK2, TK3 to read and write TK1 up to three tracks to write 79 letters or characters; TK2 can write up to 40 characters; TK3 can write up to 107 characters.

2, Tak-shing commonly used bar code card | two-dimensional bar code card introduced
Is divided into two-dimensional bar code information capacity stackable up to 1K (such as PDF417, Code 49, Code 16K, etc.) and a matrix density of higher-dimensional bar code information (eg, Code one, Aztec, Date Matrix, QR code, etc.). Stacked two-dimensional bar code on the form of multi-line stub from the one-dimensional stacked bar code, matrix-type two-dimensional bar code in the form of a matrix composed of the corresponding element in the matrix position, said with the emergence point of the binary "1", empty appears that the binary "0" from the point of permutations and combinations to determine the meaning of the code says. You can use laser or CCD readers read. Tak-shing two-dimensional bar code can be in any language (including Chinese characters) and the binary information (such as signatures, photographs) encoding, and can be selected by the user varying degrees of error correction levels to and in the case of symbols to recover all the damaging information. Widely used in the Social Security Card / Medicare Card / Admission Form / Code Card / ID and other fields.
 

① PDF417 codes: PDF417 is an open bar code systems. PDF417 portability of PDF for the data files (Portable Data File) abbreviation, whichever is similar to a bar code data file can store more information, a PDF for each code a storage capacity of up to 1,108 alphanumeric (Bytes), Ruo Jiang can be stored digitally compressed to 2,729 Bytes. Each PDF417 bar codes are stacked by the 3-90, but in order to facilitate scanning, the four weeks Jieyou quiet empty area, the water calm, quiet space is divided into an empty area and vertical static empty area, should be at least 0.020 inch.
② CM Code: Compact Matrix code, code map using perforated positioning technology and image segmentation. Perforation through the analysis of information and sub-location information to be completed by two-dimensional bar code image recognition and processing.
③ GM yards: grid matrix code, code figure from the square macro modules, each macro block from 6 x 6 square unit modules can store a certain amount of data.

Tak-shing, barcode cards (security bar code card):
① Normal production of bar code card is used to print or printing PVC card-based bar code printed on the surface often referred to as plain language, it is easy to copy after the theft.
② the surface of the bar code printed or ink-jet production, the surface production of easy to break, affecting credit card when you read and easy to wear.
③ Tak-shing, the adoption of international standards for printing bar-code technology standards for encoding software generates barcodes, printing clearly, and never wear.
④ Tak-shing bar code card anti-counterfeiting technology can effectively solve the barcode card will not be copied or not to be worn system card problem.
⑤, compared with the traditional magnetic card, barcode card security Tak-shing, will not fall outside interference caused by magnetic or loss of information.
⑥ can produce a variety of bar code cards, widely used in: securities trading cards, IDs, ID card, code card, medical card.

Tak-shing ordinary one-dimensional bar code card:
Arranged by a set of rules section, and air, as well as the corresponding characters of the tag, "Article" refers to the lower part of the reflectivity of light, "empty" refers to a high light reflectivity of the part, these articles and empty data on the composition of Expression of certain information, and can be read with the universal bar code equipment, converted into computer-compatible binary and decimal information.
① UPC Code: The code system is mainly used for business systems, the code length is fixed at 12.
② EAN Code: The code system is mainly used for goods coding, there are two types: EAN-13 codes and EAN-8 Ma.
③ cross 25 yards: The code system used is a random variable length of continuous self-checking digital code system.
④ 39 Ma (Code 3 of 9): The code system used is the length of the random variable discrete self-checking letter of the word-type code system.
⑤ Codabar (codabar): The code system is mainly used for logistics, is a variable-length discrete self-checking digital code system.
⑥ 128 Ma (Code128):) is a continuous variable length alphanumeric code system.

IC Card Intelligent is a kind of shape, like a credit card, the card package, integrated circuit chip card also known as: IC card, smart card, it will have storage, encryption and data-processing capabilities in an integrated circuit chip module packaging and credit card-sized in plastic card-based, they constitute the IC card. IC card with a magnetic, anti-damage properties of cryptographic operations, durable and strong, good security, storage, data high security, data storage capacity, application equipment and systems network environment, low cost, IC card and complete variety of models, technical specifications mature People are universal attention, have been replaced by an increasing number of field applications and other data on magnetic cards. Are widely used: financial, taxation, public security, transportation, post and telecommunications, communications, services, health care, insurance, commerce and many other fields 

Tak-shing production of IC cards in strict compliance with ISO7816 standards, common contactless IC card can be simply divided into the following categories:
A. non-encrypted memory IC card: card chip electrically erasable programmable read-only memory EEPROM, as well as the address decoding circuitry and instruction decoding circuitry. Memory card is a passive-type cards, usually synchronous communication. Card storage convenience, in many occasions can replace the card. But these IC card is not equipped with security functions, which are generally used for storage do not need to confidential information.
B. Security Logic IC card: On the basis of non-encrypted storage card encryption on the increase in logic circuits, through the efficacy password means to protect the card data for external access is open.
C: CPU card (microprocessor IC card): The IC card with a microprocessor CPU features, storage unit (including the random-access memory RAM, program memory ROM (FLASH), user data memory EEPROM) as well as the chip operating system COS and so on, with COS of the CPU card is equivalent to a micro-computer, not only has data storage capabilities, both the command processing and data security protection.
