AI Technical Summary
Technical Problem
Electronic devices cannot read data from the encrypted sector of the physical card because it is not sure of the key of the sector, resulting in the inability to copy sector data to the virtual card, and the user cannot use the virtual card to interact with the card reading device.
Method used
By acquiring the first verification data and the second verification data sent by the card reading device, the electronic device may determine at least one candidate key and determine the target key by multiple verification data to read the data in the encrypted sector.
Benefits of technology
It solves the problem that electronic devices cannot read encrypted sector data, ensuring that users can use virtual cards to interact with card reading devices normally.
