Oh. The ones I'm referring to are the modern Amazon lockers & such, reliant on modern technology. Courier goes up, enters auth code. It then asks you to scan a pkg. Then there's the prompt, is the pkg: SMALL, MEDIUM, LARGE, X-LARGE? Upon selection, it pops open a corresponding door. One pkg per locker. Rinse & repeat until all pkgs delivered to lockers, and recipients are notified of delivery.

Once you get the hang of it, it's actually super slick & helpful for everyone.

Kind of related but not as high-tech or secure, some nice apartment complexes are being built with sizeable delivery rooms. Which works unless you've got a klepto in your complex.
