Frequently Asked Questions

Q: Can this card be printed with a standard ID card printer?
Yes. The blank PVC surface is compatible with dye-sublimation and thermal transfer printers from Zebra, Epson, Canon, and similar brands. No special coating is required.

Q: Is the 4K memory enough for both access control and cashless payment applications?
Yes. The DESFire EV1 architecture allows up to 28 independent applications. A typical configuration uses one application for access credentials and another for stored value or transaction logging, with remaining memory for future use.

Q: Can I order custom UID ranges or pre-encoded cards?
Yes. DO RFID Reader supports custom UID assignment and file structure encoding as part of OEM/ODM services. Contact us with your specific encoding requirements for a quote.

Q: What is the typical delivery time for a 1,000-piece order?
Standard lead time for blank cards is approximately 10-15 working days after order confirmation. Custom encoding or printing may add 5-7 working days depending on complexity.

Q: Is this card compatible with my existing MIFARE Classic system?
DESFire EV1 readers support backward reading of MIFARE Classic cards. However, DESFire EV1 cards require readers that support ISO 14443-A and the DESFire protocol. Most modern access control readers are compatible, but we recommend testing a sample before bulk deployment.

Q: Do you provide samples for compatibility testing?
Yes. We offer sample units for testing. Contact our sales team to request a sample card for your reader and software validation.
