Can a Digital Euro Pay With No Network and No Visa?

This week, in Strasbourg, the European Parliament votes in plenary on a project that spent years on the drawing board: giving the euro a digital form, issued by the central bank, that anyone could hold in an app the way they now keep banknotes in a wallet. On 23 June, the economic affairs committee had already made its call, by forty-three votes to fourteen. After years of reports and consultations, the digital euro is leaving the laboratory.

Behind the institutional vocabulary sits a very concrete question for whoever is paying: what would a currency look like that was no longer a line on a bank statement, but a value lodged in the phone, usable even when the network drops? The answer rests on a detail the central bank likes to repeat: part of the payments would happen offline, from one device to another, with no server keeping a record.

Paying without going through an American company

When you tap your card on a terminal, the transaction usually runs on the rails of two American companies. According to the European Central Bank, Visa and Mastercard handle sixty-one percent of card payments in the euro area, and nearly all cross-border settlements. On top of that comes the rise of dollar-backed stablecoins, digital tokens that move the American currency around outside any European counter.

The issue is not just monetary pride. A foreign payment infrastructure means a third party that sets the fees, writes the rules and, in theory, could one day restrict access. Christine Lagarde has turned it into a sovereignty argument: having a public means of payment, guaranteed by the central bank, that depends neither on a private network nor on a decision made in Washington. For the user, the promise reads more plainly: one more option, free at the point of payment, owned by no one.

What offline really changes

The most tangible novelty is not in the grand speeches, it is in a quiet mode: offline payment. Two phones, or a phone and a terminal, exchange value directly, without passing through a server. The central bank describes something modeled on cash: settlement happens locally, between the two devices, and no detail is recorded by a bank, a provider or the institution itself. Only the payer and the payee know what was paid.

In practice, that means paying in a tunnel, on a train with no signal, at a village market where the reader cannot connect, or on an evening when the card network goes down, as the euro area has already seen. Where a card becomes an inert rectangle the moment the connection fails, the digital euro would keep circulating. You reclaim a capability you thought belonged only to the banknote: paying without depending on an antenna or a server switched on somewhere.

To this is added a confidentiality that electronic payment had erased. Every card transaction leaves an exploitable trace: amount, place, time, merchant. The offline mode gives the act of buying back the opacity of cash. For many, that is the only argument that truly counts.

Three thousand euros, not one more

Still, this euro is not built to sit idle. Lawmakers settled on a holding cap of around three thousand euros per person, with no return: no interest accrues on the balance kept. Above it, a so-called "waterfall" mechanism automatically sweeps the surplus into the linked bank account; conversely, if you pay more than you hold, the shortfall is drawn from that same account. The digital euro is designed as a purse, not a savings book.

That cap is no technical shyness, it is a political precaution. If everyone could park their savings at the central bank, deposits would flee the commercial banks, the ones that lend and finance the economy. The comfort promised to the user, public money in the pocket, therefore stops where the balance of the banking system begins. The dependency does not vanish: it shifts from the card network to an account you keep, after all, at a bank.

Privacy, read to the letter

The promise of discretion deserves to be read closely, because it is not uniform. Offline, the protection is real, close to that of cash. Online, it is thinner: payments are pseudonymized, meaning the central bank cannot identify you, but your provider still sees your transactions go by, just as today. "Like cash" thus holds only for the offline half of the story.

Europe's data guardians have flagged a deeper difficulty. Guaranteeing, in a digital system, the physical proximity that makes cash safe is hard: a so-called "relay" attack can, in theory, make two phones look side by side when they are in fact talking at a distance over the internet. Reproducing the banknote exactly, its anonymity included, remains an engineer's tall order.

An option, not an obligation

None of this will exist for a while. A technical pilot is due to start in early 2027 with a handful of providers, for a first issuance envisaged around 2029, and the text calls for a two-year phased rollout. Until then, banknotes are not going anywhere: the duty to accept cash is even reaffirmed. The digital euro adds to the means of payment, it replaces none of them.

What is at stake in Strasbourg is therefore less a break than a choice of infrastructure: deciding whether the citizen will have, alongside the card and the banknote, a third instrument that works with no network, no foreign middleman and without leaving its trace everywhere. The share of autonomy regained is real, but it comes fenced in: capped at three thousand euros, tied to a bank, and fully discreet only when you pay offline. The right question to ask this new euro is not "can it pay," but "what control does it take back, and from whom, of the kind we handed over without noticing."
