Abstract
An electronic entry device such as a door lock includes a display that uses substantially no power when a static image is presented. Such a display can be “always on” and be used to display information to users of the entry device on a continuous basis. In some embodiments, the persistent display is an e-ink display. In some embodiments, the persistent display may present a scannable code, such as a QR code, that is statically displayed on the persistent display when a new product is unboxed. The persistent display can also present weather, news, scheduling, or other information.
