Doorknob - Reminder / Doorknob

Doorknob - Reminder
Doorknob - Reminder

Forgetting stuffs is a shared memory for most of us. Rarely did we realize what was missing, not until we are at the door of our house or while we need to make a call desperately. To make things worse, by that time either we cannot remember where we put them or it is far from reach.
Reminder is a doorknob that checks your important stuffs. Whenever you rotate the doorknob triggers a scan for designated items. The door will not open unless you have brought with you everything you preset or confirm that you have been warned. Reminder doorknobs play as checkpoints between spaces, prevent you from leaving important stuffs at you-don’t-know-where.
