Here's a concise summary of US patent 11328286:

US Patent: 11328286

• Title: Multi-function electronic payment card and device system
• Assignee: CardWare Inc
• Inventor: David Wyatt
• Filing Date: April 21, 2020 (Application No. US16/854,829)
• Issue Date: May 10, 2022
• Abstract: Embodiments include multi-function electronic payment card and device systems capable of generating a programmed magnetic field of alternating polarity based on a speed of a card swipe. This allows the device to emulate a standard credit card for use in electronic readers. The system also includes methods for user control to authorize or manage credit, debit, cash, cryptocurrency, and card-to-card transactions. Furthermore, it describes generating limited-duration credit card numbers for a predetermined number of authorized transactions, and the device's ability to interact with similar devices for funds or credit/debit transfers.

Plain-Language Overview of Independent Claims:

The full text of the independent claims for US11328286 is not provided in the given document. However, based on the "Summary of the Invention" section, the patent generally claims:

1. An apparatus for emulating a magnetic stripe card: This apparatus comprises a thin, card-shaped body containing memory for multiple identification data, a processor, and a user interface for selecting specific data. It also includes a magnetic card reader detection unit to sense proximity to a standard magnetic card reader. An inductor assembly, controlled by the processor, generates an alternating magnetic field in the reader's vicinity. This field encodes the selected identification data and is designed to be read by the magnetic read head of a standard reader.
2. A multi-function electronic device for card-to-card transactions: This device features a Near-Field Communication (NFC) unit, a touch sensor array, a display, a motion rate detection array, and memory for user and currency data. A processor initiates card-to-card transactions between two such devices upon detecting proximity and receiving user input via the touch sensor array. The transaction involves exchanging stored currency and user data via the NFC unit.
3. A method for performing a secure transaction: This method involves a multi-function electronic device receiving an input signal from a user, which enables its NFC unit. The device then receives an indication of a transaction's currency amount. Subsequently, the device generates a limited-duration credit card number and transmits it to the transaction's recipient.
