Frequently Asked by Corporate Buyers

01.Will these keyfobs work with Hikvision, Dahua, or other access control systems?

Yes, absolutely! Our MIFARE Classic 1K keyfobs are fully compatible with major systems like Hikvision, Dahua, ZKTeco, and most standard 13.56MHz ISO14443A readers. They operate at the standard frequency and protocol used by these brands. If you're integrating with a specific model, we recommend testing a small sample batch first (we offer free samples for qualified buyers). Just let us know your system details, and we can confirm compatibility or provide pre-encoded fobs tailored to your setup.

02.How secure are the keys and data on these keyfobs?

Our keyfobs use the genuine NXP MIFARE Classic 1K chip with sector-based Key A/Key B authentication and factory-burned unique UIDs (4-byte or 7-byte, non-modifiable). This provides a good level of security for many access control, attendance, and low-value payment applications. Duplication is difficult without knowing the sector keys, and lost fobs can be immediately disabled in your system software.

That said, as manufacturers, we want to be transparent: the MIFARE Classic encryption (Crypto-1) is an older standard and has known vulnerabilities that allow advanced attacks in lab conditions. For standard everyday use (e.g., office/building access), it's reliable and widely deployed worldwide. If your project requires higher security (e.g., financial transactions or high-risk environments), we recommend upgrading to MIFARE DESFire or MIFARE Plus chips-we offer those alternatives as well. We're happy to guide you on the best option.

03.Can we lock certain sectors and leave others open for our own consumption system (e.g., canteen or vending)?

Yes, this is one of the key advantages of MIFARE Classic 1K! The chip has 16 independent sectors, each with its own Key A and Key B. We can pre-program unified keys across all fobs, unique keys per fob, or customize access conditions-locking some sectors for access control while leaving others writable for your internal applications like balance top-ups. Just provide your requirements during ordering (e.g., which sectors to lock/open and desired keys), and we'll handle the pre-encoding at no extra setup cost for bulk orders.

04.What is the defective rate for these keyfobs?

Our defective rate is extremely low-typically under 0.1% based on our in-house testing and customer feedback over years of production. Each fob undergoes full ultrasonic welding, chip functionality testing, and quality checks before shipping. In the rare case of any defects, we offer a straightforward replacement policy: simply contact us with photos or details, and we'll ship replacements free of charge.

05.Can you match an existing keyfob shape exactly (custom mold)?

Yes, we specialize in customization! We can replicate most existing shapes using custom molds (minimum order quantity applies, usually 5,000–10,000 pcs depending on complexity). We also offer standard shapes with modifications like epoxy coating, metal rings, or anti-metal layers. Send us a sample or detailed drawing, and our engineering team will provide a quote and prototype within 7–10 days.

06.What certifications do these keyfobs have?

Our MIFARE Classic 1K keyfobs are produced under ISO 9001 quality management, and materials comply with RoHS, REACH, and CE standards. The chip itself is original NXP with full ISO14443A compliance. If you need specific certifications (e.g., IP67 test reports), we can provide documentation upon request.
