I’m a dentist and own a fläsh teeth-whitening device. It uses a contact chip card to authorize a limited amount of treatment time and operates without an internet connection.

Has anyone successfully reverse-engineered the card system or modified the device to work without purchasing additional time cards?

I’m interested in identifying the chip, understanding how the remaining time is stored, and finding any documented projects or firsthand experiences with this particular system.

My goal is to remove the usage restriction while keeping the device’s treatment settings and safety features working correctly. I can share photos of the card, circuit boards, and component markings.

Any relevant information or links would be appreciated.

Does anyone know where i can find a lens for dental videography? Like in the picture
