System, method, product, and apparatus for autonomous transaction initiation via unprompted machine-readable signals

Abstract

A mobile computing device, an electronic receiving device, and a system for autonomous, unprompted transaction initiation are disclosed. The mobile initiator is configured to generate a signed data payload containing a public key and selectable data attributes, outputting them as a machine-readable signal. Crucially, this signal is initiated by the mobile device independently of any prior data-modulated signal from an external receiver. The electronic receiving device monitors for this unprompted signal, verifies it using the public key, and modifies its operational state accordingly. Disclosed embodiments include hybrid and concurrent processing architectures where devices maintain persistent dual-states to support both traditional terminal-initiated polling and autonomous mobile-initiated handshakes. By decoupling the transaction sequence from legacy interrogation signals, the system enables spatial, unprompted commercial negotiations and secure state transitions anchored by cryptographic verification and unique identifiers.
