1. A method comprising:
detecting, by a first mobile device and using a direct radio communication scheme, a second mobile device in proximity of the first mobile device;
exchanging, by the first mobile device and using the direct radio communication scheme, a first encrypted message with the second mobile device, the first encrypted message having been encrypted using an encryption key and an encryption algorithm stored on the first mobile device, wherein
the first encrypted message authorizes a processing of a payment between the first mobile device and the second mobile device,
content of the first encrypted message is inaccessible to the second mobile device,
receiving, by the first mobile device and from the second mobile device using the direct radio communication scheme, a second encrypted message indicative of one of a completion or a denial of the payment;
decrypting, at the first mobile device and using the encryption key and a decryption algorithm installed in the first mobile device, the second encrypted message to obtain a response indicative of the completion or the denial of the payment; and
displaying the response on a display of the first mobile device.
