Mifare 1K Cards,  ISO Standard Mifare 1K Smart Cards High Quality with Low Prices. Mifare ISO 14443A Module Blank White PVC Cards,MIFARE 1K  Full Color Offset Printing Cards, MIFARE 1K Silk Screen Printing Cards,  Mifare Classic contactless card with 1K bytes EEPROM that complies with ISO 14443A .

MIFARE 1K Cards are reported the most widely used contactless smartcard technology for smart card transactions. MIFARE Classic 1k contactless technology introduced in 1994. First transport scheme in Seoul using MIFARE Classic 1k in 1996.

Mifare Classic 1K Contactless Card,MIFARE Classic contactless card with 1K bytes EEPROM that complies with ISO 14443A.The mifare Classic 1K S50 is the most widely used contactless smart card in the market. Contactless smartcards are used in many applications nowadays. Contactless cards are based on radio frequency identification technology (RFID). The mifare Classic 1k S50 card has 16 sectors of 4 data blocks each. The mifare Classic 1K S50 design and implementation details are kept secret by its manufacturer. The mifare Classic 1K S50 card is a member of the mifare product family and is compliant with ISO 14443 up to part 3. ISO 14443 part 4 defines the high-level protocol.

The mifare Classic 1K card has some built-in security features. The communication is encrypted by the proprietary stream cipher CRYPTO1.Keys The 48-bit keys used for authentication are stored in the sector trailer of each sector . mifare Classic 1K S50 uses symmetric keys.Authentication Protocol mifare Classic makes use of a mutual three pass authentication protocol that is based on ISO 9798-2 according to the mifare documentation.

The mifare Classic 1K S50 is a contactless smart card that is used extensively in access control for office buildings, payment systems for public transport, and other applications. According to the Mifare Classic 1K S50 complies with parts 1 to 3 of the ISO standard 14443-A, specifying the physical characteristics, the radio frequency interface, and the anti-collision protocol. The Mifare Classic 1K S50 does not implement part 4 of the standard, describing the transmission protocol, but instead uses its own secure communication layer. In this layer, the Mifare Classic 1K S50 uses the proprietary stream cipher CRYPTO1 to provide data confidentiality and mutual authentication between card and reader.

The Mifare Classic tag is essentially a memory chip with secure wireless communication capabilities. The memory of the tag is divided into sectors, each of which is further divided into blocks of sixteen bytes each. The last block of each sector is the sector trailer and stores two secret keys and the access conditions for that sector.To perform an operation on a specific block, the reader must first authenticate for the sector containing that block. The access conditions determine which of the two keys must be used.

MIFARE Classic 1K was the first IC to be used in high volume public transport ticketing in a major transport project in Seoul, Korea. Continuing this success, cities such as London, Beijing, Taipei, Pusan and many more are adopting MIFARE as the contactless interface platform for the present and future.MIFARE Classic 1K is primarily used in closed systems as fixed value tickets (e.g. weekly or monthly travel passes) or as tickets where value is extracted from the card by the service provider.From May 2010 onwards, a MIFARE Classic 1K variant is also available with a 7 Byte UID. For future outlook regarding the 4 Byte UIDs see 4-7 Byte UID.

Mifare 1K Cards:1024 byte memory is organised as sixteen sectors, each of which is made up of four blocks and each block is 16 bytes long. The first block in the memory (Block 0) is read-only and is set in the factory to contain the four-byte serial number (UID), check bytes and manufacturers data. The last block of each sector (Blocks 3, 7, 11, 15……59, 63) is the Sector Trailer Block which contains the two security Key codes (Key A and Key B) and the Access bits that define how the sector can be accessed.Taking into account the Serial Number/ Manufacturers Block and the Sector Trailer Blocks then there are 752 bytes of free memory for user storage. For all Read and Write operations the Mifare card memory is addressed by Block number (in hexadecimal format).

Mifare 1K Reader:A reader that supports Mifare 1K card (obviously) which is to be exact a reader that supports ISO14443A/B or ISO15693 (contactless standard). A reader that can read contactless standards compliant contactless using the same framework as ISO7816 compliant contact cards.MIFARE Classic is predominantly used in public transport infrastructure, there are a considerable number of installations using the chip technology also in access management implementations.

NXP has developed the MIFARE MF1ICS50 to be used in a contactless smart card according to ISO/IEC 14443 Type A.The MIFARE MF1ICS50 IC is used in applications like public transport ticketing where major cities have adopted MIFARE as their e-ticketing solution of choice.

-Public transportation.
-Access control.
-Event ticketing.
-Gaming & identity.

An intelligent anticollision function allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field.

Simple integration and user convenience:
The MF1ICS50 is designed for simple integration and user convenience. Which could allow complete ticketing transactions to be handled in less than 100 ms. Thus, the MF1ICS50 card user is not forced to stop at the reader leading to a high throughput at gates and reduced boarding times onto busses. The MIFARE card may also remain in the wallet during the transaction, even if there are coins in it.

Several security measures like mutual challenge and response authentication, data ciphering and message authentication checks support the protection of the system against various attack scenarios. The UID of the IC as a base of key diversification supports the security concept.
