Compatibility guide

Hotel credential compatibility starts with the installed system.

A reliable card order begins with evidence from the property—not an assumption based on colour, shape or a familiar product description.

Working takeaway

Confirm the current working credential, reader environment and encoding responsibility before approving the production construction.

Why this decision matters

Buyers often search by a familiar card description, yet two visually identical credentials can carry different internal configurations. The safest route is evidence-led: identify the installed environment, separate technology from material and artwork, then validate the proposed finished construction before production.

What must be identified

Record the property, door or reader use, a verified system reference and a working credential. Photographs help with construction, but cannot prove the internal technology.

Separate three decisions

Technology, physical construction and artwork are separate approvals. A luxury surface does not establish read performance, and a compatible technology does not approve a material.

Use a controlled sample

Where uncertainty remains, test the final proposed construction in the intended environment. Record the sample revision and do not substitute components after approval.

Release production in writing

The quotation and proof should capture quantity, artwork revision, numbering, encoding responsibility, packing and delivery destination.

Decision checklist

What to settle before ordering.

01
Name the readers, doors or zones the credential must operate.
02
Provide a verified system reference and, where possible, a working card.
03
State who owns encoding, key management and validation.
04
Freeze the tested construction, artwork revision and order details in writing.

Review access-control card specifications

Send the intended use, current credential or system reference, quantity and delivery city. The response can then focus on what is confirmed and what still needs a sample.
