The central bank of Denmark, Nationalbanken, today announced its new offline payment system which means Danes will be able to pay digitally at the store — even when the internet is down.

This means both credit card payments and cellphone payments go through at the counter up to 7 days into an internet breakdown, because of a new technological solution which is being rolled out at grocery stores first.

Pharmacies will be added to the system later this year.

7-dages offline-kortbetalingsberedskab på plads i dagligvarekæder... og snart også på apotekerne | Danmarks Nationalbank

Alle voksne danskere, der har et dansk udstedt betalingskort fra Dankort, Mastercard eller Visa kan nu betale med deres fysiske kort eller wallets på mobilen i de fleste landsdækkende dagligvarekæder i mindst en uge, selvom der sker et nedbrud i kortbetalingsinfrastrukturen, eller internettet ikke virker.

@randahl Airplane inflight card payments have been doing this for ages. So nothing new technically as far as I can tell.
@harrysintonen @randahl We had such type of bank cards (issued by bank Snoras) in Lithuania at about 1993-2010. Then Snoras bankrupted.
@Jurkis Note that this is on the payment system side, rather than specific card. So any card will work.
Not any card. Danish cards. Probably mostly a regulatory thing: Danish banks consent to the risk of 7 days of outstanding payments on debit cards, but foreign banks do not.
@michael @Jurkis Sure. Similar limitations likely apply in each country individually to limit fraud. What I meant with there was that you don't need some kind of a special card for it to work. The change applies to existing cards, that is.
