Are the fobs or cards numbered sequentially?
No they are not

Can the fobs or cards be printed on?
No, fobs cannot be printed on as they are too small. Thick 1.8mm proximity cards could be difficult to print upon as they have a textured finish. Thin 0.8mm cards can be printed on

What are the numbers printed on the fobs & cards?
The EM chip inside each fob or proximity access card is pre-programmed with Hexadecimal number that provides an 18 digit number during the manufacturing process. The first 10 digit number is the Unique I.D number (U.I.D) and is printed on the fob

The second 8 digit number is the Wiegand code number (Not printed on fobs), However, both 10 & 8 digit numbers are printed on the proximity access cards

Are these numbers important?
Yes, all 26 bit Wiegand card readers will ‘read’ the 10 digit U.I.D number in a binary format, yet some card readers that require a remote control in order to delete lost or missing fobs or cards might not accept you manually entering the 10 digit U.I.D number but will only accept the manual entering of the 8 digit Wiegand number
A lot of PC access control software will only display the 8 digit Wiegand number. It is ultimately down to the particular system or format used and/or required

How would I obtain the 8 digit Wiegand number?
The easy way is with the RD-USB-KP , a simple ‘plug and play’ unit that you plug in to your computer, open up Windows Note Pad, present a card or fob and the 8 digit Wiegand number is displayed

Does your PC access control system require a USB card dispenser if I use key fobs or cards?
Yes and no – for key fobs specifically. You cannot manually add key fobs or cards to the software using the 10 digit U.I.D number. You can use either a door reader or a USB card dispenser, however, if you have several hundred cards, then using a USB card dispenser will save an awful lot of time

What item do they work best with – card reader or keypad/card reader?
They will work perfectly with any of our items or any Proximity Wiegand 26 bit format
