Why do some cards work in one reader but not another?

Reader power, antenna design, chip platform, protocol handling, and finished-card tuning all affect performance. '13.56 MHz' alone does not guarantee identical field behavior.

What personalization details should be frozen before mass production?

At minimum: artwork version, numbering/encoding logic, data format, and print position tolerances. Need answers tailored to your project? Send your key concern and ZHENZHEN NEW MATERIALS can reply with a use-case-specific recommendation.

Product Q&A

Q:What is the difference between a dual interface card and a hybrid card?

A dual interface card usually uses one chip accessible through both contact and contactless interfaces. A hybrid card often combines separate chips or separate functions in one body. For system simplicity and data consistency, many buyers prefer dual interface when supported by the application.

Q:Will the contact module affect RF performance?

It can, if antenna design, module embedding, or lamination control is poor. That is why finished-card RF verification matters more than inlay-only testing.

Q:How do I know whether I need secure MCU or just memory architecture?

If the project uses keys, authentication logic, secure applets, or high-risk data, start with secure MCU / secure OS. If it is only simple stored data for a lower-risk environment, a memory structure may be enough.

Q:What is the most common quoting mistake?

Not defining the interface standard, personalization requirement, and material/durability target at the beginning. Those three points affect sample direction and price quickly.

Q:Can the same card body be used in hot climates?

Yes, but material choice matters. PVC is common for standard indoor use. PETG or PC is often preferred where heat resistance, bending resistance, or longer life is more important.
