Abstract
A method includes capturing a preliminary quick response (QR) code displayed by a device of a desired service provider. The preliminary QR code has a substantially blank region and comprises an identification feature of the desired service provider. The identification feature is analyzed to determine an identification credential of the desired service provider. In response to determining that the identification credential matches a stored identification credential stored in a server of an interaction provider, a QR code is requested from the server. One or more directed acyclic graphs (DAGs) are generated. A first DAG is received from the server. A first portion of the QR code is generated based on the first DAG and added to the preliminary QR code to generate a first intermediate QR code. One or more recursion operations are performed until all DAGs are received and the QR code is generated from the preliminary QR code.
