Abstract: A method is provided. The method includes receiving a request to conduct a transaction with a merchant, requesting approval of the request, receiving approval of the request, verifying the transaction, receiving a first data, receiving a second data, determining a first distance between the first computing device and the second computing device based on the first and second data, determining that the first distance between the first computing device and second computing device satisfies a first predetermined distance threshold, receiving a third data, the third computing device being associated with the second user, determining a second distance between the third computing device and the second computing device based on the third and second data, determining that the second distance between the third computing device and the second computing device satisfies a second predetermined distance threshold, and approving the transaction.

Abstract: A computer-implemented method includes receiving a transaction initiation request from a first user via a first computing device. A first micro-location parameter relating to a micro-location of the first computing device is received. Approval of the transaction initiation request is requested from a second user via a second computing device. Approval of the transaction initiation request is received from the second user via the second computing device. A second micro-location parameter relating to a micro-location of the second computing device is received. The transaction is approved if the micro-locations of the first and second computing devices indicate that the first and second computing devices are at least a predetermined distance from each other.
