Buying Compatible Access Cards in Bulk: Installer & Facility Guide

What do I need to specify to place an order?

A clean spec turns a quote around fast and gets credentials that work on the first tap. We do not need your access-control software or a sample reader; we need the data your panel expects to see. For most open prox jobs that is the Wiegand format, the facility (site) code, and the card-number range. For smart credentials it is the chip family and how your head-end enrols cards.

If you only have a working sample card, send us its specifics or read it with a format-identification tool. The format name plus a known card number lets us match the bit structure exactly so the credential we encode presents the data your readers already accept. The more precise the spec, the fewer surprises at the door.

• Format: e.g. 26-bit H10301, 34-bit H10306, 37-bit H10304, a 35/48-bit corporate format, or a chip family such as genuine NXP MIFARE Classic / genuine NXP DESFire / iCLASS legacy.
• Facility / site code: the fixed number your panel checks (8-bit FC for 26-bit; wider for higher-bit formats).
• Card-number range: start and end of the sequential block you want.
• Form factor: ISO PVC card, clamshell, key fob, or adhesive tag/disc.
• Quantity and any printing needs (logo, slot punch, numbering on the artwork).

Encoded credentials vs. blank programmable cards

There are two ways to buy. Encoded credentials arrive ready to use: we encode each blank to your format, facility code and the exact card numbers you specify, so they badge in immediately. This is the right call for the open 125 kHz prox and legacy formats where the data your readers expect can be encoded directly to a compatible credential, and it is what most installers order.

Blanks are unencoded programmable credentials for shops that enrol in-house or run secured smart systems. For secured credentials such as genuine NXP MIFARE DESFire with AES, HID Seos, and iCLASS SE/Elite, we supply compatible blank credentials of the correct chip family and your own system enrols them with its own keys — exactly like ordering blanks through the OEM channel. The keys, and your site security, stay in your hands; we simply hand you the correct media and your head-end does the rest.

How does sequential numbering work?

For open formats, every credential is a facility code plus a unique card number, so the card number is what your panel actually grants on. Order a contiguous block — say 1001 through 1500 — and you can bulk-import the range into your access software in one action instead of registering credentials one at a time.

Tell us where to start and we continue cleanly from your last batch so numbers never collide or repeat across reorders. If you want the printed number on the card face to match the encoded number, say so; the human-readable number and the encoded number are independent unless you ask us to align them.

Can I mix cards, fobs and tags on one order?

Yes. Form factor is just the housing around the chip, so a card, a key fob and an adhesive tag carrying the same chip and encoded with the same format and facility code all read identically at the door. Mix them freely in one order — ISO cards for staff badges, fobs for contractors, tags for assets or vehicles — as long as the underlying technology matches your readers.

The one rule is frequency: a 125 kHz reader only reads 125 kHz media and a 13.56 MHz reader only reads 13.56 MHz media. If your site runs dual-technology readers, we can supply dual-frequency credentials so one piece of plastic works across both.

Minimum quantities, reorders and lead time

Standard open formats carry low minimums, and per-unit pricing improves as volume rises — the savings versus OEM list pricing widen the more you buy. Some managed or proprietary formats carry a higher minimum because of how they are produced; we flag that on the quote rather than letting you discover it at checkout.

Reorders are simple because we keep your spec on file: same format, same facility code, and the next sequential number block continuing from your previous order. Reference your earlier order and we pick up exactly where it left off, with no renumbering and no repeated card numbers entering your system.

How do I QA a batch before rollout?

Always test before you deploy a large batch to live doors. Pull a few credentials from across the range — including the first and last numbers — and badge them at a real reader to confirm the format, facility code and numbering all decode the way your panel expects. Checking both ends of the block catches any off-by-one or range error before it reaches a user.

Then enrol the sample numbers in your access software and verify a grant and a deny. If the test credentials behave, the rest of the contiguous block will behave the same. Only after that sign-off should you distribute or activate the full batch.

• Read a sample at a live reader and confirm format + facility code decode correctly.
• Test the first and last card numbers in the range, not just the middle.
• Enrol samples in your software; verify both a successful grant and a correct deny.
• Confirm form-factor frequency matches the reader (125 kHz vs 13.56 MHz).
• Check printing, slot punch and any artwork alignment before bulk distribution.

Why buy compatible instead of OEM at volume?

Compatible credentials are electrically and logically identical to what your readers expect — same frequency, same format, same facility code and numbering — as a cost-effective alternative to OEM credentials. Across a multi-site rollout or an annual reorder cycle, that difference is what separates a credential line that pinches the budget from one that disappears into it. The credentials still work exactly the same at the door; you simply stop paying the brand premium on every piece of plastic.

We are an independent manufacturer and supplier and are not affiliated with, authorized by, or endorsed by any access-control manufacturer; brand names describe compatibility only. For open and legacy formats we encode a compatible credential that presents the exact data your readers already accept; for secured smart systems we supply compatible blanks your own head-end enrols. Either way, send us the spec and request a quote and we will confirm format support, minimums and lead time before you commit.
