What makes the MIFARE DESFire EV2 card durable
MIFARE DESFire EV2 cards are typically made from high-quality materials such as PVC and composite PET/PVC. These materials provide excellent resistance to wear and tear, making the cards suitable for various environments, including those subject to frequent handling.
The card boasts a data retention capability of up to 25 years, ensuring that the information stored remains intact over a long period, which is essential for applications requiring reliable data storage.
With a write endurance of up to 500,000 cycles, the MIFARE DESFire EV2 card can withstand extensive usage without degrading its performance. This makes it ideal for applications that involve frequent data updates or transactions.
This feature guarantees transaction-oriented data integrity by protecting against data loss during the transaction process. If a transaction is interrupted, the card can revert to a consistent state, ensuring that no partial or corrupted data is stored.
The inclusion of an on-chip backup management system enhances reliability by allowing for data recovery in case of unexpected failures. This system helps maintain data integrity and ensures that critical information can be restored if needed.
