# do you need internet access to pay a crypto invoice

You need an active internet connection on whichever device holds your wallet and submits the transaction. A crypto invoice is an address paired with an exact payment amount and a cryptographic mandate, but that transaction must reach peer-to-peer nodes to be validated and included in a block. Without connectivity at the moment of signing and broadcasting, your payment sits as an unsubmitted message on your hardware or software wallet.

While the sender must be online to broadcast data, the merchant side works slightly differently. A seller can generate or print a static invoice offline, or display a QR code containing their public key and requested amount without internet access at that exact second. However, to confirm that your funds have actually arrived, the vendor's system eventually needs internet access to read the public ledger. For real-time confirmation, both buyer and seller rely on connected nodes.

## how the transaction moves

When you scan a NOWPayments invoice QR code or copy a destination address, your wallet app drafts a digital transaction. This draft includes the recipient public address, the asset amount, the network fee, and your digital signature created by your private key. Signing a transaction happens entirely locally on your device, which is why hardware wallets can sign transactions while disconnected from the internet. However, broadcasting that signed signature to nodes across Bitcoin, Ethereum, or Polygon requires network access.

Once your connected device broadcasts the signed payload, nearby nodes validate the cryptographic signature against your public key. They confirm that your wallet balance covers the amount plus network fees, then pass the payload along to other nodes until block builders or miners pick it up. The invoice status updates from pending to paid only after the merchant's payment processor detects this broadcast on the public chain.

## offline signing and captive portals

If you use a cold storage hardware wallet, you interact with offline signing regularly. The hardware device itself never connects to the internet; it signs the data blob air-gapped via USB or QR code scan. You then use a hot wallet software app on an internet-connected smartphone or computer to broadcast that signed data to the network. The signing step requires no connection, but the transmission step strictly does.

Travelers paying invoices abroad occasionally run into connection drops, spotty cellular roaming, or restrictive public Wi-Fi network captive portals. If your connection drops after you hit send, check a public block explorer using your transaction hash once reconnected. If the hash does not appear on the explorer, the broadcast failed before reaching the peer-to-peer network, and your funds remain safely in your wallet ready to be sent again.
