Abstract
In an approach for enabling communication between offline devices to perform secure transaction, a processor sends information in an optically recognizable first code including a response type, an identity of the first device and a type of optical reader associated with the first device. A processor receives encoded information in an optically recognizable second code. A processor extracts a user identifier and the one-time password associated with the registered second device. A processor determines that a user certificate associated with the user identifier exists in a local repository. A processor validates the one-time password associated with the registered second device with the user certificate using a public certificate associated with the first device, the one-time password associated with the registered second device and the one-time password seed. A processor authenticates the user.
