Tuomas Valimaki, a board member at the Bank of Finland, announced that Finland together with Sweden, Norway, Denmark and Estonia will roll out offline card payments. According to Reuters, the decision follows unexplained cable damage in the Baltic Sea and fears that sabotage linked to the war in Ukraine could silence data links.
Valimaki told the agency that only one in ten Finns still uses cash as a main method, so losing connectivity could freeze daily trade overnight. Every card transaction needs an international line, and cutting a cable could leave shop tills idle.
He added that payments run on Visa and Mastercard rails owned in the United States. A political dispute could switch them off without notice. Finland therefore plans a domestic instant-payment network and reserve accounts to let households tap their savings during shocks.
Christian-Marc Lilflander from NATO’s defense planning section said in Helsinki that finance ministers must now sit at the security table. Payments, he argued, stand next to energy and telecoms as pillars that an adversary may test in hybrid conflict.
How Will Shoppers Pay When Cables Go Dark?
Under the Nordic scheme, payment terminals will keep an encrypted log of every tap or chip entry when links drop. Staff will clear the log once service returns. Sweden wants cover for basic shopping for up to seven days, according to its central bank.

Norway and Denmark already operate early versions, while Estonia is finishing its timetable. In each case, the plan is to let people buy groceries and fuel even during a cyber incident or storm.
The daily routine will hardly change for shoppers. They will still tap a card, and the receipt will state that the payment is queued. Merchants carry the risk if the card later bounces, but governments may cap losses.
What Lessons Does The UK Get From Nordic Planning?
Britain has felt the pain of broken banking links twice already in 2025. According to letters from the Treasury Committee, Barclays customers could not reach the bank’s app or website for three days around 31 January, the self-assessment deadline.
Downdetector later logged trouble at Lloyds, Nationwide, TSB and Santander on 28 February, payday for many workers, as reported by Computer Weekly. A senior technologist told the magazine that the cluster of outages hints at a shared software provider.
Branch closures magnify the shock. Research from SAS shows the average constituency lost more than half its branches between 2020 and 2023. When the only cash machine is a smartphone, a silent server can stop groceries reaching the dinner table.
Dame Meg Hillier, who chairs the Committee, has asked nine banking chiefs for a full record of every breakdown since 2023, the hours lost and the compensation paid. She said banks have cut face to face service while online tools still fall over.
The Nordic blueprint gives London a live example. Payment terminals in Britain already contain storage chips, so a software patch could let them queue transactions in the same way. Regulators and banks would need to set limits and anti-fraud rules, but the concept stands ready. Westminster may look north before the next payday outage cuts the lights again.
