Abstract
Devices, systems and methods are provided for playing back video or other dynamic content at a point of interaction with one or more users via a device that is configured on a sticker, label, card or other substrate. The device is self-powered and employs ambient radio frequency energy harvesting to charge a renewable, rechargeable energy storage element. The device has a display for displaying static content until dynamic content such as the video content is output in response to a user input. The display on the device can be used for outputting the video content, or the device can transmit the video content to an NFC-enabled smart phone for display without the smart phone having to download the video content from the internet.
