  "country": "US",
  "title": "Central Bank Digital Currency for Phones and Watches",
  "original_title": "Digital currency (virtual payment cards) issued by central bank for mobile and wearable devices",
  "summary": "This patent describes a system for using a central bank-issued digital currency on mobile devices, generating a special 3D code for payments that can be scanned or read via near field communication.",
  "what_it_does": "This patent outlines a system for managing and transferring a digital currency, called ZCU, issued by a central authority. A user on a mobile or wearable device can request to issue digital currency. The system prompts the user for authentication, then accesses their account, which holds payment data. When a merchant requests payment, the system matches merchant IDs, authorizes the transaction by transferring the digital currency from the user's account to the merchant's. This transfer can happen by displaying a special 3D optical code (a 'zcode') on the device's screen for scanning, or via near field communication (NFC). Once the payment is complete, the digital currency is deactivated. The zcode itself is described as a 3D machine-readable code with specific visual elements like a 'round global circle' and 'squares arranged in a round circle grid'.",
  "what_it_does_not_cover": [
    "Digital currency systems not controlled by a central issuer (e.g., decentralized cryptocurrencies like Bitcoin).",
    "Payment methods that do not involve generating and displaying an optical code or using NFC.",
    "Transactions where the merchant ID does not match the user's requested merchant.",
    "Digital currency that is not a 'Z currency' (ZCU) as defined in the patent.",
    "Systems that do not involve a mobile or wearable device for the transaction."

  "abstract": "Provided is a method for digital currency transfers via a mobile and wearable device. The method may include receiving a transfer request with a transfer amount in digital currency and user identification data associated with the user, retrieving payment data of the user associated with the identification data, generating an optical code encoding the payment data and the transfer amount. The method may continue with providing the optical code on a screen of the mobile and wearable device. On scanning of the optical code, a transfer receiving request is created. The method may continue with receiving a transfer receiving request to perform a payment transaction associated with the user, accessing a user account maintained by a currency issuance unit, and transferring the transfer amount in the digital currency from the user account to a recipient account associated with the recipient identification data.",
