Package Contents: 1 UFR Mifare card programmer 1 USB cable 3 Mifare 1K cards 1 CD containing free software - uFR Examples for Mifare cards programming in Java, Java Applet, JavaScript, Lazarus, Delphi, C + + Builder, Microsoft® Visual C + +, Net, Microsoft® Visual C #, Microsoft® Visual Basic.net - uFR Card Formatter - for independent Mifare card programming Mifare ISO/IEC 14443 The uFR software contains the library for working with: Java, Java Applet, JavaScript, Lazarus, Delphi, C + + Builder, Microsoft® Visual C + +. Net, Microsoft® Visual C #, Microsoft® Visual Basic.net, so that developers that are using any of these languages has an opportunity to protect their applications, to create new identification systems or even to use the Mifare® card for secure transmission of data limited with memory capacity of the Mifare® card. Ideas and creativity of the user are the limits for this device application. According to the API specification, uFR has the following features that were implemented to work with four basic methods of authentication and cards reading and writing: - emulation of a linear address space with Mifare card, - direct access block for reading and writing, - indirect block access to the sector by combining the card and also blocks the sector for reading and writing, - decrement and increment block value for read and write 4 byte values, - linear card format where for the entire ID card sets unique keys and bits of access, - enrollment sector trailer blocks on the cards, - which facilitates the calculation of the of bytes value containing access bits.
