Do you think that self-checkout machines are beneficial for both retailers and customers? Why or why not?

Self checkout

i am putting some reviews without any research only as per experience what we have faced.
Pros:
Self checkout will reduce the labor expensive and staff requirement.
It saves money after spending one time at assets.
Upgrade your business to next level
it saves a lot time for your business and customers.

Cons:
Hard for every Market and customers.
Needs to be problem solver.
you should have exact database otherwise there are big chances of loss.
Take more time for data entry for normal customers.
every item must have barcode
Barcode should be unique for every item otherwise problem persist.
Inventory should be updated.
Removing items take more time.

We suggest every seller of item should use unique identifiers to grow your business as using the same barcode for any product is big headache for other businesses and even your own business. solution is to buy unique Identifiers from codesforamazon.com to grow business.
