Electronic currency offline payment method and payment collection method

This invention describes a system for two devices to exchange digital money directly, even when they don't have an internet connection. One device initiates a payment by wirelessly connecting to another, sharing its digital wallet information, and then receiving the payment details. It verifies the transaction, digitally signs it, and records the exchange. The specific claims narrow this to systems where the payment amount is typed in using a keyboard.

Why it matters: Since 2021, the integration of hardware-backed secure elements and cryptographic accelerators in standard mobile devices has made implementing the claimed security control and digital signing modules more accessible and robust.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSecure software, cryptographic modules, hardware integration
