Frequently Asked Questions
Do Mifare cards work with Proximity readers?
No. Since Mifare (13.56 MHz) and Proximity (125 kHz) operate on different frequencies, they are not compatible. However, dual-frequency cards can work with both readers.
Are Proximity cards secure?
Proximity cards have low security levels because they lack encryption. While sufficient for basic access control, Mifare DESFire should be preferred for high-security systems.
Which Mifare model is better?
Mifare Classic is budget-friendly and widely used, but Mifare DESFire EV2/EV3 offers the highest security level and flexibility. Classic is recommended for general use, DESFire for critical applications.
Can I change cards later?
Yes, but you'll also need to change your reader infrastructure. That's why choosing the right technology from the start saves cost. Contact us for consultation.
Conclusion
The choice between Mifare and Proximity cards depends on your business's security needs, budget, and future plans. While Proximity is an economical solution for basic access control, Mifare is indispensable for systems requiring multi-application and high security.
