US 2024/0193584 A1 · HARDWARE WALLET FOR DIFFERENT HOST DEVICES TO PERFORM DIGITAL PAYMENTS

Abstract

A hardware wallet can enable management of digital assets across different devices, such as electronic devices and payment cards. The hardware wallet can include a memory card, operable across at least one smartphone and at least one payment card, that stores instructions to perform operations. When executed by at least one processor, the operations can include authorizing a smartphone to perform a first electronic payment with a first cryptographic asset associated with a first key of a digital wallet stored in the memory card while the memory card is disposed in the smartphone. The operations can further include enabling a payment card to perform a second electronic payment with a second cryptographic asset associated with a second key of the digital wallet while the memory card is disposed in the payment card.

Dependent claims

A memory card comprising:

one or more non-transitory computer-readable storage media storing computer instructions, which, when executed by one or more processors, cause the memory card to:
authorize a smartphone to perform a first electronic payment with a first cryptographic asset associated with a first key of a digital wallet stored in the memory card,
wherein the smartphone is authorized to perform the first electronic payment while the memory card is disposed in the smartphone;
and
enable a payment card to perform a second electronic payment with a second cryptographic asset associated with a second key of the digital wallet,
wherein the payment card is enabled to perform the second electronic payment with the second cryptographic asset while the memory card is disposed in the payment card,
wherein the memory card is operable across at least one smartphone and at least one payment card.

4 more elements

A method, comprising:

with at least one processor and a memory card including one or more non-transitory computer-readable storage media that stores computer-executable instructions, causing the at least one processor to execute the instructions to perform operations comprising:
authorizing a smartphone to perform a first electronic payment with a first cryptographic asset associated with a first key of a digital wallet stored in the memory card,
wherein the smartphone is authorized to perform the first electronic payment while the memory card is disposed in the smartphone;
and
enabling a payment card to perform a second electronic payment with a second cryptographic asset associated with a second key of the digital wallet,
wherein the payment card is enabled to perform the second electronic payment with the second cryptographic asset while the memory card is disposed in the payment card,
wherein the memory card is operable across at least one smartphone and at least one payment card.

4 more elements

A system comprising at least one processor and a memory card, the memory card including one or more non-transitory computer-readable storage media that stores computer-executable instructions to cause the at least one processor to perform operations comprising:

authorizing a smartphone to perform a first electronic payment with a first cryptographic asset associated with a first key of a digital wallet stored in the memory card,
wherein the smartphone is authorized to perform the first electronic payment while the memory card is disposed in the smartphone;
and
enabling a payment card to perform a second electronic payment with a second cryptographic asset associated with a second key of the digital wallet,
wherein the payment card is enabled to perform the second electronic payment with the second cryptographic asset while the memory card is disposed in the payment card,
wherein the memory card is operable across at least one smartphone and at least one payment card.
