EM4100 Card Programmer - Reader / Writer RFID Device

This EM4100 card programmer is used to program 125 KHz EM cards and fobs (EM4100 / TK4100) with custom card numbers.  Card numbers can be programmed either using the 10 digit EM number (usually starting with 00 or 000) or with the facility code (0-255) & card number (1-65,535).  On an EM card, it is usual for these numbers to be printed on the card - the first number is the 10 digit EM number and this is followed by three numbers (facility code) with a comma followed by five numbers (card number).  On key fobs not all of the numbers may be printed. See the image for more information.

Standard EM4100 tags are read only.  To write EM4100 tags, you will need to use T5577 tags (click here to view) which will emulate EM tags.

With the included software, you can write cards continuously with consecutive numbers.  You can also load card numbers that you wish to write from a text file.
