Programmable electronic devices on containers

A system comprising:

• a memory;
• a processor operatively coupled to the memory, the processor configured to:
• receive data comprising proximity sensor data of an electronic display device attached to an object;
• determine whether the data satisfies a criterion comprising a proximity threshold, wherein satisfying the criterion indicates a mobile device of a user is proximate to the electronic display device;
• transmit a first message to the mobile device over a wireless connection;
• receive a second message from the mobile device, the second message comprising user data;
• and
• responsive to receiving the second message from the mobile device, presenting, by the electronic display device, a message comprising the user data.

A non-transitory computer readable storage medium comprising instructions to cause a processor to:

• receive, by an electronic display device, data comprising proximity sensor data;
• determine, by the electronic display device, whether the data satisfies a criterion comprising a proximity threshold, wherein satisfying the criterion indicates a presence of a mobile device of a user;
• transmit, by the electronic display device, a first message to the mobile device over a wireless connection;
• receive a second message from the mobile device, the second message comprising user data;
• and
• responsive to the receipt of the second message from the mobile device, present, by the electronic display device, a message comprising the user data.
