OK ... here's Idea No.14 (those of you wondering about the previous 13 will need to trawl back through my earlier posts. Enjoy)!
Being relatively late in coming to the internet, on-line shopping and all the rest, I realised early on (a few years back now) that the crunch (the nub, the
Achilles Heel) of the whole idea of shopping on line (and, up to a point, "just in time" stock transactions) was and is:- the distribution and delivery of the goods.
People don't live as they used to, and Mums tend not to stay at home these days. So what about deliveries to private addresses? And how about the many folk (myself included) who hang out in "difficult to find" addresses, in shared accommodation, high-rise buildings and all the rest (that is, places that drivers of over-sized Sprinters* prefer [or pretend] not to know about). I'm sure I'm not the only one who has had to
traipse to the Sorting Office in town (limited hours) just to pick up something that, as it turned out, I may as well have bought in town anyway!
Having just witnessed a Yodel** driver attempting to drop off a package at someone's house, I was yet again reminded of the need for some sort of secure individual dropping off point, bunker, closet (or what-have-you).
I believe that in some parts of the world (
eg, the United States) houses in suburban areas have what look a bit like lockable "Biffa"*** bins outside, for stuff to be dropped off at. However, I'm not sure how the driver gets access to those (maybe they are left unlocked by the owner, then latch when the lid is closed following delivery, or perhaps each vendor has their own bin (?) - someone must know)!
So ... here's the thought:- why not have a window-less closet, bunker, bin (we need to come up with a name here) that works by "key access". The owner would have the master device (hand-held, IR, Bluetooth, whatever ... technology to be decided), and be able to program time-slots, access levels
etc. The lock mechanism would be a solenoid operated sliding bolt (or some such suitable arrangement). Meanwhile, the couriers would have their own devices to access the door (lid) according to the delivery code (or whatever). Therein lies the problem, of course:- the couriers would need to agree on the details of the coding!

"It's yet another opportunity for thieves", you may say. But to that I would respond:- "in Modern Britain, what isn't"?

And ... our gadgets may as well include a camera (suitable triggered) as well. After all, what is less secure than the electricity and/or gas "utility boxes" that adorn modern dwellings in Britain?
Remember folks, where you heard it first (I only want 5% for the rights to the concept, plus 1% of the value of every secure delivery)!
