Frequently Asked Questions
What is the difference between EM4200 chip and other chips?
Re: EM4200 is a classic 125kH z low-frequency chip, which has the advantages of strong stability, wide compatibility and moderate cost. It is suitable for short-distance identification scenarios such as access control and attendance. It has stronger anti-metal interference than high-frequency chips and lower cost than UHF chips.
What is the minimum order quantity? Do you support small-batch customization?
Re: The minimum order quantity for regular standard cards is 100 pieces, and 500 pieces for customized cards; small-batch (100-500 pieces) customization can be negotiated, and only a small customization fee is charged to meet the needs of small and medium-sized enterprises.
Do the products support export? Can relevant certifications be provided?
Re: Export is supported, and international certifications such as CE and ROHS can be provided; commercial invoices, packing lists and other customs declaration materials are provided according to customer needs to assist in smooth customs clearance.
What if there is a quality problem with the product?
Re: Within 7 days after receiving the goods, if there are quality problems such as chip performance failure and appearance damage, photos or videos can be provided for verification, and we will provide free replacement.
