Most access control cards used remain blank for security reasons which can make identifying them difficult. A good place to start would be looking at previous invoices or documentation from the supplier. Here you should hopefully see a product description, SKU code or even the MPN (manufacturer part number).
Next, you will need to know your access control systems format. The majority of proximity cards are distributed in the 26-bit format (H10301) excluding those used with specialised systems; these may use a different format.
If you are unsure what the format of your cards previously was, check on the box your cards were delivered in or again any supporting paperwork you may have.
In an access control system, each batch of cards contains a unique ID number which differentiates it from the rest; this can also be referred to as a sequence number. If you’ve previously printed a batch of cards 1 to 250 then the sequence start number for the next batch of cards would be 251.
If you are still not sure what the sequence start number of your proximity cards are, you can typically find it on the boxes label from your last card order.
Another key piece of information needed when reordering your cards is the facility code. This code is a number from 0 to 255 that is assigned to your location when first encoded.
If you have a large organisation, then there may be more than one facility code on your cards so its important to look for this when reordering your cards.
If you are struggling to find this on the front of your cards, have a look at the box the cards came in or check previous invoices from earlier orders.
