Frequently Asked Questions
What is the difference between LF and HF keyfobs?
LF (125kHz) keyfobs like TK4100 are read-only and commonly used for simple access control. HF (13.56MHz) keyfobs like MIFARE S50 support read/write operations and higher security, ideal for advanced access systems and payment applications.
Can I get samples before placing a bulk order?
Yes, we provide free samples for testing and evaluation. Contact us with your chip and size requirements, and we will send samples to verify compatibility with your system.
What is the minimum order quantity (MOQ)?
Our standard MOQ is 500 pieces. However, we can accommodate smaller quantities for sample orders or initial testing. For custom colors or laser engraving, higher MOQs may apply.
How do I choose the right chip for my access control system?
The chip choice depends on your existing system. Check your reader's specifications for supported frequencies and protocols. If you are unsure, provide your reader model, and our technical team will recommend the compatible chip option.
Are these keyfobs waterproof?
Yes, all our ABS keyfobs are rated IP68, meaning they are fully waterproof and dustproof. They can withstand rain, splashes, and harsh environmental conditions, making them suitable for outdoor use.
Can you print our logo on the keyfobs?
Yes, we offer silk-screen printing and laser engraving services for custom branding. Silk-screen printing supports both single-color and multi-color logos, while laser engraving provides permanent marking that will not fade over time.
