Not yet as a normal consumer payment. The digital euro’s planned offline mode is being tested and prepared, not offered through a universal app today. When it becomes available, you will set up a digital-euro account with a participating bank or other payment-service provider, load an offline balance while connected, and then transfer value by tapping the payer’s and recipient’s enabled devices together over NFC. The devices verify the transfer locally, so the payment itself does not require mobile data or Wi‑Fi.
Your phone would need more than NFC: it would need an approved digital-euro wallet, an eligible tamper-resistant secure element, and support from a participating provider. You would reconnect later for operations such as replenishing or moving the offline balance back to ordinary bank money.
What an offline digital-euro payment actually is
An offline digital-euro payment is a local, proximity transfer between two enabled devices. It is not a conventional card transaction waiting for an issuer’s online authorisation. The European Central Bank’s preparation work describes the transfer as an exchange of cryptographically secure tokens directly between devices, with no online system involved at the moment of payment.

The design is intended for situations in which a phone cannot reach a network: poor mobile coverage, a temporary internet failure, a power or communications emergency, or a shop whose connection is unavailable. “Offline” does not mean that the entire digital-euro account works without connectivity. The account must be prepared while online, and some later account operations still require a connection.

What happens during the tap
The payer authorises an amount in the digital-euro payment application. The payer’s device and the payee’s device then communicate at close range, expected to be through near-field communication (NFC). Each device checks the cryptographic data and updates its locally protected value. The transfer is designed to settle almost immediately without contacting a central server.
The ECB pilot FAQ says that value received offline can be spent again offline before the device reconnects. That makes the function closer to handing over cash than to using a card whose authorisation must reach a bank in real time.
What you would need before going offline
Offline use depends on several pieces working together. Having only a banking app or an NFC-capable handset would not be enough.
1. A digital-euro account with a participating provider
You would first open a digital-euro account through a bank or another payment-service provider in the euro area that participates in distribution. The provider would supply or enable the wallet software and handle the connection between your account and the Eurosystem infrastructure when online account operations are required.
2. An offline wallet balance loaded while connected
Before losing connectivity, you would move an amount from your online digital-euro account into the device’s offline balance. This preparation step is essential: an empty offline balance cannot be created at the point of sale. The wallet would show how much is available for offline transfers, subject to the final rules on holding and transaction limits.

3. An approved wallet and secure element
The wallet must be integrated with an eligible secure element. A secure element is tamper-resistant hardware that protects stored value, transaction processing and cryptographic keys from extraction or alteration. It also supports controls such as protection against spending the same value twice.
The ECB has identified several possible forms, including an embedded secure element, an integrated secure element and an eSIM-based secure element. The exact implementation will depend on the final technical and certification requirements.
4. NFC and a supported proximity path
The expected phone-to-phone exchange uses NFC proximity communication. The two devices need to be close enough for their NFC radios to establish a session. A shop could use a compatible terminal rather than another phone.
An NFC symbol on a handset is not proof of compatibility. The phone would also need the approved wallet integration, an eligible secure element and a provider that supports the offline digital-euro service.
How to pay offline, step by step
The following sequence reflects the ECB’s pilot design. Menu names and authentication screens will depend on the provider and the final wallet software.

- Connect to the internet before you need the feature. Use mobile data or Wi‑Fi to sign in to the digital-euro wallet and confirm that your account and device are enabled for offline payments.
- Load the offline balance. Choose the wallet’s funding or offline-balance function, select an amount, and authorise the transfer from your online digital-euro account. Wait for the wallet to confirm that the value is stored locally. Do not assume that money visible in the online account is automatically available offline.
- Check the available offline amount. Review the wallet’s offline balance and any displayed limits before leaving coverage. Keep enough headroom for the payments you expect to make; a payment cannot exceed the spendable offline value or the applicable transaction cap.
- Open the payment function when you are ready to pay. Enter the amount in the wallet or select the amount requested by the merchant. The app may ask you to unlock the device or approve the transaction using its configured security method.
- Bring the devices together. For a person-to-person transfer, place the payer’s and recipient’s enabled phones close together with NFC active. At a shop, bring your phone to the compatible terminal. The pilot describes this as a proximity exchange, so neither device needs an internet connection for this step.
- Wait for both confirmations. Keep the devices in position until the wallet or terminal indicates that the transfer succeeded. A confirmation on only one side is not enough; the recipient should see the received value before the devices are separated.
- Retain the local receipt or transaction record. If the wallet provides an offline receipt, keep it until you can reconnect and the account synchronises. Do not retry repeatedly after an uncertain result, because you could create duplicate attempts or confuse which transfer completed.
- Reconnect when you have coverage. The wallet can synchronise its records and perform account functions that are unavailable offline. If you need to return unused offline value to ordinary bank money, use the wallet’s defunding function while connected.
Receiving and spending value while still offline
The pilot design allows a recipient to spend value received offline before reconnecting. For example, one person could receive a digital-euro transfer in a low-coverage area and use part of it at a nearby compatible shop without first finding Wi‑Fi.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsThis ability does not remove the need for device protections or limits. Every transfer still has to pass the wallet’s local checks, and the wallet may refuse a payment when the available offline value or permitted transaction amount has been reached. The recipient should wait for a clear success indication before treating the funds as available.
What happens during a network or power outage
Mobile or Wi‑Fi outage
A loss of connectivity should not stop a properly prepared proximity payment. Because the payer and payee exchange the cryptographic value directly, the payment does not wait for a mobile network, home router or central authorisation response.
Weak coverage or a dead zone
The design is aimed at poor coverage as well as complete disconnection. You still need a charged, enabled device and a compatible recipient device or terminal. Moving a few centimetres, removing a case that interferes with NFC, or following the wallet’s positioning prompt may be necessary for the proximity session to start.
Power failure
Offline capability does not make a phone operate without power. If the battery is empty, the secure element and wallet cannot complete a transfer. An outage may also disable a shop’s terminal even if your phone is charged. The digital euro is intended to improve resilience, not to replace a charged device or functioning payment hardware.

Privacy: what your bank can see
The European Commission describes offline payments as peer-to-peer validation: the payer and payee directly verify that value moved between them. During the local exchange, transaction details are not intended to be visible to the bank or the European Central Bank in the same way as an online payment record.
That privacy applies to the payment event, not to every operation around it. Anti-money-laundering and counter-terrorist-financing checks are expected when you fund or defund the offline balance. Reconnecting can also allow the wallet and provider to reconcile records and enforce the system’s safeguards.
Offline payments are intended mainly for small purchases. Specific holding and transaction limits have not been stated in the available official material. The European Commission says those limits will be set through a Commission implementing act based on a risk assessment. Do not rely on a quoted euro amount from an unofficial guide until that act and the final wallet rules exist.
How the secure element protects the balance
The secure element is the hardware trust anchor for offline value. It is designed to make the stored tokens and cryptographic keys difficult to read, copy or modify, even if someone gains access to the phone’s operating system. It also performs or supports the checks needed to stop the same offline value being presented twice.

Phone, smart card and other possible devices
Phones are the clearest pilot form factor because they combine a screen, NFC and secure hardware. The ECB has also investigated smart-card approaches, including cards with their own battery and cards without a battery that use a bridge device. These are design options under development, not retail instructions you can follow today.
When comparing a future phone or card implementation, check these characteristics rather than looking only for an NFC logo:
| Question | Why it matters |
|---|---|
| Which device stores the offline value? | The secure element and its recovery rules determine how the balance is protected. |
| Does the transfer require NFC proximity? | The payer and recipient must be able to bring the devices or terminal close enough to communicate. |
| How is the wallet funded? | Offline value must be loaded while connected through a participating provider. |
| How is it defunded? | Returning value to commercial bank money requires a connection through the provider’s distribution component to the Eurosystem back end. |
| What are the holding and transaction limits? | Limits reduce financial-crime and double-spending risks; final amounts are not yet established. |
| What hardware accepts it? | A merchant needs a compatible terminal or another enabled device, not merely a generic contactless reader. |
How to move the balance back to your bank account
Funding and defunding are different from making a local payment. Funding puts value into the device’s offline balance before disconnection. Defunding removes unused offline value and returns it to commercial bank money or the connected digital-euro account.
Recommended Free Tools
The ECB pilot material says defunding requires the device to connect through the payment-service provider’s distribution component to the Eurosystem back end. In practice, you would reconnect, open the wallet’s balance-management function, choose the amount to return, and complete the provider’s authentication or compliance checks. A phone-to-phone tap cannot perform this back-end account operation while both devices remain offline.
What is available today?
The ECB pilot FAQ describes offline person-to-person transactions as a feature being tested. The ECB’s general digital-euro information says the legislative process and technical preparation are still ongoing. Consequently, there is no universal consumer app, final supported-device list or published schedule of offline limits that applies across the euro area.
Availability will depend on several decisions still being completed: the legal framework, provider participation, wallet certification, secure-element support, merchant hardware and the implementing act that sets risk controls. A claim that any NFC phone can already make an offline digital-euro payment is therefore inaccurate.
Troubleshooting an attempted offline payment
The wallet says offline payments are unavailable
- Reconnect and check whether your provider has enabled the offline function for your account.
- Confirm that an offline balance was loaded; money in the ordinary online balance may not be spendable locally.
- Check for a wallet, operating-system or security update required by the provider.
- Verify that the device contains the eligible secure element and has not been replaced, reset or put into a state that disables the protected wallet.
The two devices do not detect each other
- Unlock both devices and open the payment screen rather than leaving the wallet in the background.
- Turn NFC on if the wallet requires a system setting, then hold the devices close together and try the marked NFC areas.
- Remove a thick or magnetic case temporarily and keep the devices still until the exchange completes.
- Make sure the recipient is using a compatible wallet or merchant terminal; ordinary contactless hardware is not automatically a digital-euro endpoint.
The payment is declined
- Check the remaining offline balance and the maximum amount allowed for a single offline transaction.
- Try a smaller amount only if the recipient has confirmed that the first attempt did not complete.
- Reconnect and synchronise if the wallet reports that its offline state needs updating.
- Use another payment method if the terminal or recipient device is not certified for offline digital-euro transfers.
The result is uncertain
Do not make several immediate retries. Ask the recipient whether a completed receipt or balance change is visible, and preserve any on-screen transaction reference. Once connectivity returns, synchronise the wallet and contact the participating provider if the records do not agree. The secure element is intended to prevent double spending, but careful handling avoids creating multiple disputed attempts.
A practical preparation checklist
- Open the account with a participating bank or payment-service provider.
- Install and activate the provider’s approved digital-euro wallet.
- Confirm that the device has the required secure element and NFC support.
- Connect to the internet and load the offline balance before leaving coverage.
- Review the wallet’s available balance and displayed limits.
- Charge the phone; offline mode cannot overcome a depleted battery.
- Know whether the destination uses another enabled phone or a compatible terminal.
- Reconnect periodically for synchronisation and for funding or defunding operations.
For now, the reliable answer to “Can I pay with a digital euro without internet?” is: the planned system is designed to allow it after advance preparation, but the capability remains in pilot and technical preparation rather than being a universally available consumer service.
