Not yet as a generally available consumer service. In the European Central Bank’s planned design, an offline digital-euro payment would work only after you open an account with a participating bank or other payment-service provider, fund the offline balance while connected, and use an enabled device with NFC and an approved secure element. You would then bring the payer’s and recipient’s devices together and tap them. The value transfer would be verified locally, so the payment itself would not need mobile data or Wi-Fi. You would reconnect later to add money or move the offline balance back to commercial-bank money.
Can you pay with a digital euro without internet?
The planned offline function is designed to let a digital-euro value transfer happen between nearby devices instead of through a live central network. The European Central Bank’s pilot FAQ describes the exchange this way: “When these transactions are performed, the exchange will take place between the payer’s device and the payee’s device in proximity, without the need for to be connected to the internet.”

That does not mean a digital-euro wallet can be created or replenished while disconnected. Setup, funding and later defunding require connectivity through the payment-service provider. Offline capability is a separate, pre-funded balance intended for situations such as poor coverage, a network outage or an emergency.

The capability is still described in official material as a pilot and technical-preparation feature. The legislative process and preparation work are ongoing, so there is no universal consumer app, final supported-device list or published schedule of offline limits to follow today.

What you need before an offline payment
A digital-euro account with a participating provider
You would first set up a digital-euro account through a bank or another EU payment-service provider that distributes the digital euro. The provider would supply or support the wallet application and the processes used to fund and defund it. A normal bank account by itself would not make an ordinary phone capable of offline digital-euro transfers.
An offline balance funded while you are online
The offline wallet must be loaded in advance. The ECB’s FAQ says users would “need to fund the offline digital euro account first” before tapping a phone to a friend’s phone or a shop terminal. Funding is an online operation because the provider must transfer value into the device’s protected offline environment.
Plan this step before you travel into a dead zone or before an expected outage. If the offline balance is empty, losing connectivity does not create a way to spend from the online account; you would need to reconnect and fund it first.
A compatible secure element
The wallet needs access to an eligible secure element: tamper-resistant hardware that protects stored value, transaction processing and cryptographic keys from extraction or alteration. The ECB describes this component as providing safeguards such as protection against double spending. Candidate implementations include embedded secure elements, integrated secure elements and eSIMs.
The secure element is important because the device has to hold and update value safely while it is cut off from the online system. Software alone, or an ordinary file containing a balance, would not provide the same protection against copying or manipulation.

NFC and an approved wallet integration
The expected phone-to-phone exchange uses near-field communication (NFC). Both sides need the appropriate wallet integration, and a merchant needs an enabled terminal for a shop payment. Seeing an NFC logo in a phone’s specifications is not enough: the phone also needs an eligible secure element, approved software integration and support from a participating payment provider.
How an offline digital-euro payment would work
- Connect and create the account. Use a participating bank or EU payment-service provider to establish the digital-euro account and activate its wallet.
- Prepare the device. Confirm that the wallet is enabled for offline use and that the device contains an eligible secure element. The final activation screens and supported models have not been published as a universal consumer specification.
- Fund the offline balance. While online, move value into the offline digital-euro account. This creates the spendable balance held in the protected device environment.
- Start the payment. In the payment application, enter or authorise the amount. For a person-to-person transfer, the recipient opens the corresponding receiving function; for a purchase, the merchant presents an enabled terminal.
- Bring the devices together. Tap or hold the payer’s phone against the recipient’s phone or terminal so the NFC proximity connection can exchange the payment data.
- Let the devices validate the transfer. The payer and payee devices verify the transfer locally. No mobile-data or Wi-Fi connection is required for this exchange.
- Keep the confirmation shown by the wallet. The application should display the result of the local transaction. The exact wording, receipt format and recovery screens will depend on the final wallet implementation.
- Re-spend received value if needed. The pilot FAQ says funds received offline can be spent again offline before the device reconnects.
- Reconnect for account operations. When you need to add more funds or move the offline balance back to commercial-bank money, reconnect the device through the provider’s distribution component.
What “offline” means technically
An online card or account payment normally asks a remote system to authorise a transaction in real time. The proposed offline digital-euro flow instead transfers cryptographically secure tokens directly between nearby devices. The ECB preparation report describes the settlement as near-instantaneous and says no online system is involved in the transfer itself.

The European Commission calls this a peer-to-peer validation: the payer and payee directly verify that the transfer of value has effectively happened. The central infrastructure is not being queried at the moment of the tap.
This design explains both the benefit and the limits. It can continue to function where a radio network is unavailable, but it cannot perform online account administration at the same time. A later connection is needed to reconcile the offline balance with the provider’s systems and to carry out funding or defunding.
Which operations need a connection?
| Operation | Expected connection requirement | What happens |
|---|---|---|
| Create the account | Online | The bank or payment-service provider sets up the digital-euro account and wallet. |
| Fund the offline balance | Online | Value is loaded into the device’s protected offline environment. |
| Person-to-person tap | No internet during the exchange | The payer’s and payee’s enabled devices communicate over NFC and validate the transfer locally. |
| Payment to a shop terminal | No internet during the exchange | The enabled phone and terminal exchange the payment in proximity. |
| Spend value received offline | No internet for the subsequent offline transfer | The recipient can use received funds in another eligible offline payment before reconnecting. |
| Defund the offline balance | Online | The device connects through the provider’s distribution component to the Eurosystem back end so the balance can return to commercial-bank money. |
Will it work during a network or power outage?
Mobile-network or Wi-Fi outage
This is the clearest use case. If the phone is powered, the wallet is already funded and both sides have enabled hardware, the NFC exchange is designed to proceed without mobile data or Wi-Fi. The same principle applies when coverage is poor or a local internet connection is unavailable.

Wider power outage
Offline payments are intended to add resilience during emergencies, but the phone or terminal still needs enough battery to operate its secure element and NFC radio. A dead phone cannot complete a tap. Merchant equipment would likewise need to remain powered or use an approved alternative form factor.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsOfficial ECB work has considered smart-card alternatives, including battery-powered cards and non-powered cards that use a bridge device. These are design options under development, not retail products or instructions that can be followed with any existing card.
Privacy: can your bank see the payment?
The European Commission says offline payments are validated peer-to-peer and intended mainly for small payments. During the offline exchange, payment details are not visible to the bank or the ECB in the same way as an online transaction. This is meant to provide a cash-like level of privacy at the moment of payment.
Privacy does not remove financial controls. Anti-money-laundering and counter-terrorist-financing checks take place when the offline balance is funded and defunded. The system also needs limits on how much can be held and transferred offline. The Commission says those holding and transaction limits will be established through a Commission implementing act based on a risk assessment. No official euro amount is established in the cited material, so any current-looking number would be misleading.
Security safeguards and failure boundaries
Protection inside the device
The secure element is intended to resist tampering and protect cryptographic keys, transaction processing and stored value. It is also part of the design used to mitigate double spending while devices are disconnected from the central system.

Proximity reduces the attack surface, but does not remove user risk
The transfer requires the payer and payee to be physically close enough for NFC communication. You still need to check the amount and recipient before authorising it, because a locally validated transfer can be final even though the device is offline. The pilot material establishes the technical exchange, not a promise that a provider can reverse every mistaken payment.
Offline does not mean unlimited
Holding and transaction ceilings are expected to restrict the value that can circulate without an online check. They are a regulatory and risk-control feature, not a phone setting that users can bypass. The final amounts and enforcement details remain unsettled while the framework is being prepared.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Phone, smart card or bridge device?
The phone is only one possible form factor. ECB investigations have examined alternatives for cases in which a user has no compatible smartphone or needs a payment method that can survive a particular outage scenario.
| Form factor | How the value would be protected or exchanged | Status described by the ECB material |
|---|---|---|
| Phone | An approved wallet uses an embedded or integrated secure element, or an eSIM, and exchanges value over NFC. | Expected pilot direction for offline proximity payments. |
| Battery-powered smart card | The card contains its own powered secure hardware for storing and processing the offline value. | Investigated design option. |
| Non-powered smart card with bridge device | A separate bridge device supplies the interface needed to communicate with the card. | Investigated design option. |
These alternatives should not be confused with ordinary contactless bank cards. A card would need to be part of the approved digital-euro architecture and supported by a participating provider.
What to do if an offline tap fails
The devices do not detect each other
- Check that both devices are enabled for the offline wallet function and that NFC is available.
- Keep the NFC areas close together and hold them steady for the wallet’s confirmation.
- Confirm that both devices have sufficient battery power.
- Make sure the payment application, rather than an unrelated contactless function, is handling the exchange.
The wallet has no spendable offline balance
A disconnected phone cannot fund itself from the online account. Reconnect through the payment provider, complete the funding operation and then try the offline payment again.
The recipient cannot spend value received offline
Re-spending requires the recipient’s device and wallet to support the same approved offline function. If it does not, reconnect and use an online payment route or another accepted method.
Defunding does not complete
Defunding is not a local NFC operation. Reconnect the device so the provider’s distribution component can reach the Eurosystem back end. Without that connection, the offline balance remains on the device rather than returning to commercial-bank money.
What is available today?
The cited ECB pilot FAQ identifies offline person-to-person transfers as something tested in the pilot. The ECB’s general FAQ describes the digital euro as still moving through legislation and technical preparation. Consequently, consumers should not expect a single official app that works on every NFC phone, a final compatibility database or a settled table of offline limits.
When a provider eventually offers the function, verify all three layers before relying on it: the provider must participate in digital-euro distribution, the wallet must explicitly support offline use, and the device must contain an eligible secure element in addition to NFC. Until those conditions are published for a particular product, an NFC icon is only a hardware capability, not proof of digital-euro compatibility.
Practical checklist before relying on offline payment
- Open and verify the digital-euro account while connected.
- Confirm that your provider supports the offline function.
- Check the exact phone, secure-element and wallet requirements supplied by that provider.
- Fund the offline balance before entering an area with poor coverage.
- Keep the phone charged and know where its NFC antenna is located.
- Check the recipient or merchant and amount on screen before authorising.
- Remember that offline limits may restrict the value you can hold or transfer.
- Reconnect periodically for funding, defunding and any provider checks that require the online system.
The short answer
A digital euro is expected to work offline through a pre-funded, protected wallet: two enabled devices meet over NFC, validate a cryptographic value transfer locally and can do so without internet access. The wallet must be funded online beforehand, and later funding or defunding requires a connection. Because the feature remains in pilot and preparation, exact limits, supported devices, merchant hardware and consumer availability are not final.
