You might not always trust courier companies out there to update you on the whereabouts of your package and that’s what the G.P. Stamp concept is designed to solve. This concept device is a small stamp-sized electronic chip with a built-in battery, allowing you to keep tabs on your package. It uses advanced printed electronics to ensure that it’s slim enough to look like postage stamp and critical information will be sent wirelessly to you in real time, ensuring that you’ll always be informed. This concept device features a flexible 0.2mm thick GPS circuit board and a 0.4mm thick battery cell. If it doesn’t provide enough juice, you can purchase larger stamps with longer battery life.
