## Abstract

A system is provided for automated recording of evidence of delivery of a service in a service setting. The system includes a mobile communication device, a web-based interaction component, and a service control system. The system includes a service interface device to generate an electronic signal. The electronic signal includes a first SMS transmitted to the mobile communication device and a second SMS transmitted to the service control system. The electronic signal also includes a first secured hash link executable by the mobile communication device, wherein executing the link records a first electronic evidence of service delivery. The electronic signal includes a second secured hash link executable by the service control system, wherein executing the second link records a second electronic evidence of service delivery.

## Independent claims

1. A computer-controlled system for automated recording of evidence of a delivery of a service in a service setting, said system comprising: a mobile communication device associated with a user in a service network, wherein said mobile communication device comprises predefined information about said mobile communication device and said user; a service provider-associated computer system that manages and processes delivery of services in said service setting by a service provider; an electronic device that transmits: a first short message service (SMS) signal to the mobile communication device and comprising a first secured hash link that is clicked to record a first evidence of service delivery associated with the mobile communication device; and a second short message service (SMS) signal to the service provider-associated computer system and comprising a second secured hash link that is clicked to record a second evidence of service delivery associated with the service provider-associated computer system; a processor that records an electronic evidence of service delivery in the service network by transmitting a confirmation electronic message along with a unique service proof token (SPT) to said mobile communication device and to the service provider-associated computer system, wherein said electronic evidence of service delivery is one of an event, a digitally executable location, a digitally executable location voice input, and a digital image; a blockchain device directly connected to the electronic device, wherein the block chain device comprises computer-executable instructions comprising a digitally executable SPT associated with said mobile communication device, wherein the digitally executable SPT is an electronic token identifying a start of receipt of service and an end of receipt of service; and a client electronic device directly connected to the blockchain device, wherein the client electronic device verifies said electronic evidence of service delivery by retrieving said unique SPT from said blockchain device.
