Embodiments of techniques and systems for sharing user information between proximate devices are described. In embodiments, a first device may identify a physically-proximate device that may receive user information. Upon receiving an indication that a user of the first device may desire to share user information with a user of the second device, a determination may be made as to whether the two users have matching interests. In embodiments, the interest match determination may be made by a separate interest match evaluator. Upon determination of an interest match, the first device may then send a request to share user information to the second device. If a user of the second device approves the request, user information for the user of the first device may be shared with the user of the second device. Other embodiments may be described and claimed.
