Actually just read a few talks by danes in the financial council in Denmark. They are currently reconstructing the entire payment infrastructure to allows realtime transfers of payments. For payments under $100.000, transfers are done three times a day, as is seen with services such as MobilePay (Venmo wannabe) that i believe are considered a e-money institution.
If anyone is interested then i can provide the links to the slides. They are, however, in danish.
