Migros can only win with the Subito self-scanning system.

Self-checkout is out of the question for me, as I always push around 80 products during my fortnightly shopping.

Self-scanning is too cumbersome for me as I like to have both hands free. It can also happen that I see a more appealing product a few shelves away and put the one I've already loaded back in its place.

Here's an example from last Thursday, when I did a month's shopping because I emptied the fridge while my wife was away and used up a lot of reserves.

A woman who was frantically holding a scanner in her right hand and who was constantly distracted by her companion pushing the trolley, wandered parallel to me through the Center Brügg. From time to time our paths crossed at the caddies, which were slowly filling up. As I moved from the Anna's Best convenience products towards the farmer, cocoa and coffee sector, I noticed that there was a chicken and pizzas with turkey in my trolley. So I asked the woman "if that was hers!" In fact, she had mixed up the caddy. As it was poultry, I became suspicious as we don't eat feathers, if it had been bifidus, heidi butter or parmesan I wouldn't have noticed and the products would have been paid for twice. Once by me and once by the person who scanned it!

Then I come to the conclusion: scanned is bought and you have to be careful that you put the items in the right shopping cart.

The Subito or Passabene self-scanning system is certainly advantageous, among other things insofar as the shopping process can be rationalized and the queuing at the checkouts, which is obviously almost unbearable for some customers, can be avoided, the impression of a more independent, speedy shopping process can be created, etc.
It can be assumed that such systems will become more and more established (cf. ticket counters, lending systems in libraries, etc.) and that other areas will be 'depersonalized' in this way in a few years' time.
I myself hope that, especially in MIGROS, COOP etc., the choice between self-scanning and the conventional shopping process will continue to exist. in my [subjective view, NOT intending to devalue the above-mentioned systems in general] opinion, such innovations can also "lose" important moments of interpersonal contact.
Even more than the arguments put forward by Daniel Düsentrieb and Rebecca07 [if you are really interested in my purchase from a "Big Brother perspective": go ahead, there won't be much exciting stuff to watch for long], the aspects mentioned by Istanbul apply to me. I also have the advantage of having both hands free, and it would definitely be too cumbersome to record or change the frequent changes and new decisions in the scanner, not to mention the time argument.

Well, I do 1 week's shopping at a time (for 6 people and for around CHF 350 - 450). By scanning everything myself (and "bundling" everything nicely in the shopping cart) and only paying at the payment terminal, I am clearly x times faster than: putting everything in the shopping cart, putting everything on the conveyor belt at the checkout, putting everything back in the shopping cart (completely mixed up) and finally loading everything again in the car.
Incidentally, with all these large purchases, no "foreign" product has ever ended up in my shopping cart.
And it's very easy (and takes very little time) to delete a product if you change your mind.
And because of Big Brother, we are all monitored everywhere anyway, or do all critics only pay in cash (and don't have a debit or credit card)?

@pwilms: Wow, bulk shopping for 6 people - that is of course a considerably different situation than the perspective from which the previous message was written :). If the Subito system can be used here to save time, that's great; as mentioned, I think it's ideal that you can choose between different systems.
With regard to "Big Brother", I also think that EH collects or could collect a lot of "data", but I don't feel threatened or uncomfortably observed by Migros, I simply can't imagine leaving any particularly interesting "traces"....
Kind regards and happy holidays

About Big Brother...
The Cumulus system works on the same principle: scan the card and poof - purchase recorded. Self-scanning is therefore about as "risky" in terms of surveillance.

@splash: right-:). But there is probably also some kind of sophisticated recording in the cash registers, and there may also be various more or less "hidden" cameras, USW. The possible recording of my extremely varied "purchases", which always follow the latest trends and are geared towards the preparation of the most elaborate menus and are highly inspiring, can hardly bother me (so far) with the best will in the world.
