An application or App on a payer's mobile device is used to discover people known to the user and who are in close proximity to the user at the time of a payment request. Discovery can be through searching contact lists and/or social networks of the payer and/or through the payer device discovering contacts around the payer and then searching the payer's contact or social network list to see if there are any matches. These people are then shown to the user on the user device, such as with a photo, icon, name, and/or email address. The user selects desired ones, which causes requests to be sent to the selected people, such as through text, voice, or email, to the respective devices. The selected people can then easily confirm or authorize a payment be sent to the user or to a payee.
