5. 055 IN SECURITY MODE In security mode the 6055B typically transmits OEM card data in Wiegand format data exactly as it is encoded onto the card The only exception to this is when the reader is configured to transmit the 32 bit Card Serial Number CSN in which case there are several configurable options for data output formats Application Note 25 Using the Model 6055B HID Mifare Reader HID Factory Encoded MIFARE Cards Page 2 HID can encode OEM Wiegand card data onto new MIFARE cards at the factory into the same formats provided on 125 kHz cards including the new Long Format The customer simply orders MIFARE cards with Wiegand encoding by specifying HID format number Facility Code ID range Additional fields such as Issue Level OEM Code etc Ink jetting The OEM card data bears no relationship to the unique random 32 bit CSN HID normally encodes the Wiegand OEM card data into Sector 1 of the MIFARE card and protects the data with an HID proprietary key which is not published The HID proprietary key is also securely stored in each HID MIFARE reader On HID factory encoded cards all sectors including the MIFARE Applications Directory are protected with Philips default keys except for sector 1 which contains access control data Figure 1 These keys are published and are present in most generic MIFARE readers Only HID readers have the HID keys which enable the readers to read HID access control data HID keys
6. APPLICATION NOTE 25 Using the Model 6055B HID MIFARE Reader The Model 6055B HID MIFARE Reader is a multi purpose contactless card reader writer with both Wiegand and RS232 ports as well as external control lines for LED and Beeper control Compatible Cards The 6055B is designed for use with the following MIFARE contactless smart cards HID Model 1430 with Philips S50 Standard card IC HID Model 1431 with 125 kHz proximity and Philips S50 Standard card IC Cards using Philips S50 or compatible Infineon Card IC Card using Philips Mifare Pro IC emulating the S50 in contactless mode Card using Philips Mifare Lite reads Card Serial Number only These cards operate at 13 56 MHz and meet the ISO 14443 A standard for contactless smart cards Operational Modes The 6055B HID MIFARE Reader has two operational modes Security Mode Wiegand reader function The reader defaults to this mode intended for use with an access control panel The reader will output OEM card data or the Mifare 32 bit Card Serial Number in Wiegand format This data is also transmitted in Hexadecimal format on the RS232 port Transaction Mode Non access control function The reader responds to external commands received at the RS 232 port typically connected to a host PC or micro controller The software developer or system integrator must incorporate HID s communications protocol into the host software or firmware to communicate with the reader USING THE 6
7. ansaction mode every function of the reader is under the complete control of the connected PC or controller The reader will assert the DTR control line when it successfully reads a card This alerts the host that a card has been read and can be used to trigger the customer s application program The reader continuously re transmits the CSN until an acknowledgement is received from the host The reader also sends a break signal when it powers up If the developer is using non standard keys for his application this allows the application to resend the keys only the default keys are stored in Flash memory
8. coder can encode HID OEM Wiegand data on any available sector of the MIFARE card and analyze the card to see which sectors are available It can also print the Wiegand Card ID number on the card when used with a dye sublimation printer or it can print the card numbers on standard adhesive labels Whenever the Card Encoder writes data to the card it e Locks the encoded sector with HID Proprietary Keys e Writes the HID Applications ID AID into the MIFARE Applications Directory The MIFARE Applications Directory MAD is a table of contents stored on each card Philips the developer of MIFARE technology assigns unique applications ID numbers to various suppliers and integrators The reader scans the MAD looks for a certain AID and then goes directly to that sector to read the data This is much faster than searching the entire card for data Philips recommends that MIFARE cards be encoded with the MAD in Sector 0 which HID does but this is not required for the card to function Reader Configuration Options The HID MIFARE Reader may be ordered pre configured or field programmed to look for HID data in various places on the MIFARE card and output it in various formats In the reader s model numbering scheme the last two digits allow various configurations explained in the tables below Figs 2 and 3 6055B base model X Color G Grey W White B Beige K black X Hardware Option N none 00 Beeper LED Config Options
9. create with MIFARE programmer Customer has encoded cards and does not know how they are encoded Read cards on MIFARE encoder it will try Philips default keys or any known A amp B keys which customer enters into the software Or obtain encoding information and keys from whoever originally encoded the cards Once open sectors and keys are determined use HID MIFARE Card programmer to encode If keys are unknown and are not defaults data protected by those keys cannot be read or modified If the customer does not have a MIFARE encoder they may send sample cards to HID Technical Support for analysis Application Note 25 Using the Model 6055B HID Mifare Reader Page 7 Scenario Method Comments Customer has combined Use MIFARE encoder Encoder will modify existing two groups of cards and encode HID data in MIFARE Applications some cards have a different available sector X on one directory indicating HID available sector than others group and Y on the other data in sector X or Y for HID data MAD is group Reader will search all cards available for HID AID and will read the data from the appropriate sector Customer has combined Set readers to CSN only There is no way for the two groups of cards and mode readers to find OEM data in some cards have a different various sectors without available sector than others using the MAD for HID data MAD is NOT available
10. d access control panels The easiest approach is to configure the HID MIFARE reader to output the MIFARE card s 32 bit Card Serial Number CSN as Wiegand data The HID MIFARE Reader can be pre configured to do this at the factory or it can field configured with a configuration card Unfortunately most access control panels require data formats with a fixed facility code and sequential numbering and therefore cannot accept the 32 bit data A common workaround is to cut off or truncate some of the data from the 32 bit CSN and adding a fixed facility code to synthesize 26 bit Wiegand format data However this still may result in duplication of numbers and will provide random rather than sequential card numbering This type of modification of CSN output can be configured on the 6055B Application Note 25 Using the Model 6055B HID Mifare Reader Page 4 Note that if the existing cards are Mifare Lite or Mifare Pro cards outputting the CSN in Wiegand format is the ONLY method of using these cards for access control There is no means available to encode HID OEM formatted data on these cards HID MIFARE Card Encoder The cleanest solution for the customer who already has cards and cannot use the 32 bit CSN is to purchase an HID MIFARE Card Encoder and encode the cards on site The HID MIFARE Card Encoder is a special version of the reader that connects to a PC running Windows software similar to the HID ProxProgrammer The Card En

12. s 48 bit keys typically expressed as 12 Hex characters There is one pair of keys called the A key and B key used to protect each of the 16 card data sectors Each key in a pair can be used to protect a certain function For example the A key could be required to read data in a sector while the B key could be required to write data to a sector or the A key could be required to deduct stored value from a sector while the B key could be required to add stored value To access data ina protected card sector the reader must have a matching key Keys are used to protect data from being read or changed without authorization Because each sector has its own separate key pair a Mifare card can be used to store information encoded on the cards by separate vendors for separate applications and each vendor would be prevented from modifying the other vendor s data accidentally or otherwise simply by keeping the keys secret For this to work the keys to the card s Mifare Applications Directory need to be known to all parties Separate sets of readers would be used to control each application each reader would have only the appropriate keys for its own application Non Factory Encoded Cards Many customers already own MIFARE cards that are encoded with transit vending campus or other applications and they wish to add access control functionality to those cards This can be accomplished by connecting model 6055B HID MIFARE Readers to standar
