Mobile wallet and digital payment

This invention describes a system for making secure payments wirelessly using a mobile device. The device holds a digital payment card, called an m-card, which is linked to a financial account like a credit card or cash. When paying at a store terminal, the mobile device securely transmits payment information using advanced encryption and wireless technologies like NFC or Bluetooth.

Why it matters: Filed before widespread smartphone adoption and integrated secure elements. Today, mobile devices universally support the necessary wireless communication and cryptographic capabilities, making the underlying technology readily available for implementation.
