Keycard Backup

Easily back up your Mifare Classic key card (a widely used card type) using NFC technology. The duplicated card functions exactly like the original, making it perfect for backing up access cards such as door entry cards, dorm key cards, condo access cards, digital door lock cards, and membership cards.

This process transfers data from the original card to a writable card, commonly known as a CUID card. To use this app, you will need a blank CUID card. Additionally, the app includes a built-in feature to help you find available CUID cards for purchase in your area.
