Techniques for communicating via exchanges of physical charms

Abstract

In one embodiment, a charm application enables user devices to communicate via physical charms. Upon receiving, from a first user device, a read request that is associated with the physical charm, the charm application identifies a message and an authorization list that are associated with the physical charm and previously received from a second user device. The charm application then determines whether a first user associated with the first user device is authorized to read the message based on the authorization list. If the first user is authorized to read the message, then the charm application transmits the message to the first user device. Notably, each physical charm may be exchanged between any number of users, but only read by authorized users via a user device. Accordingly, user devices may communicate private messages including any type of data with other user devices irrespective of whether technical infrastructures are accessible.
