  "title": "Smart Payment Card with Transaction Info Locked to Payment Method",
  "original_title": "Multi-function electronic payment card and device system",
  "summary": "This patent describes a smart payment card that can use various payment methods like magnetic stripes or NFC, and generates unique, single-use payment information specific to the chosen interface for each transaction.",
  "what_it_does": "This payment card device is shaped like a standard card and includes a memory, a processor, and multiple ways to connect to a payment reader. These connection options, or 'interfaces,' can include a smart card chip reader, a magnetic stripe, a radio frequency (RF) interface like NFC, or even information visible on the card's surface. For each transaction, the card generates special 'limited-use payment information.' This information is designed to work only through the specific interface chosen for that payment. For example, if you tap the card using NFC, the payment information generated will only be valid for an NFC transaction and cannot be used if someone tries to replay it through a magnetic stripe reader.",
  "what_it_does_not_cover": [
    "Does not cover payment cards where the same payment information can be used across multiple different interfaces (e.g., magnetic stripe data also working for NFC).",
    "Does not cover payment cards that do not generate limited-use payment information for transactions.",
    "Does not cover payment cards that only support a single payment interface, such as a traditional magnetic stripe-only card.",
    "Does not cover systems where the limited-use payment information is not specifically tied to the interface used for the transaction.",
    "Does not cover payment cards that do not contain a processor and memory to manage the limited-use information."

  "abstract": "A payment card device includes a thin card-shaped payment-card-standard compatible body, a memory, a processor coupled to the memory; and a payment card reader interface. The payment card reader interface includes at least one interface selected from a set of payment-card-standard interfaces consisting of: a smart card reader interface, a magnetic-stripe interface, an RF interface, an NFC interface, a display interface, an information visible on the surface of the payment card device, and a wireless interface. The payment information for a transaction is operable to be conveyed via at least one of the payment-card-standard interfaces, and includes a limited-use payment information. The limited-use payment information is limited to a use only on the selected payment card interface used at a payment card reader facility. The limited-use payment information is invalid in a use other than via the selected payment card interface.",
