Already there are some interesting Swedish efficiencies presenting themselves here in Sweden:

(1) There are no paper checks. All transactions are done electronically. Our downstairs neighbor said he’s not seen a check in over 20 years!
(2) No post offices. Public post offices were completely abandoned in 2001. So now I’m trying to figure out how one actually mails a letter.
(3) No receipt signing is necessary if you have a European credit card. You have a PIN code instead.

I’m sure the list will grow.
