Check Bitcoin invoice details before scanning a payment QR code
A scan-to-pay checklist for comparing address, amount, network, expiry, fee and merchant reference on the trusted invoice and the final wallet screen.
Check Bitcoin invoice details before scanning a payment QR code
A QR code reduces typing but does not prove who created the invoice or what the wallet decoded. The final approval must compare the trusted merchant context, full address, amount and network with the wallet screen rather than relying on the square image alone.
Bitcoin.org describes QR-based payments, wallet control, fees, public transactions and the responsibility of protecting keys. It does not certify a SignalBet payment route or merchant invoice.
Authenticate the invoice source
Open the payment instruction inside the verified account or merchant route and record its invoice reference. Authenticate the invoice channel before scanning its code. A QR code delivered by chat or search advertisement can encode an attacker's destination.
Compare the hostname and active session before exposing the wallet camera. The invoice record should include issue time and any stated expiry. Bitcoin.org supports scan-and-pay use, user control of wallet keys, selectable fees and the public, permanent nature of blockchain transaction records.
Keep network fees separate from the amount the recipient should receive. Open the payment instruction inside the verified account or merchant route and record its invoice reference. The full destination must be compared at more than the first and last characters. Compare the hostname and active session before exposing the wallet camera.
Decode every payment field
Review the full address, requested amount, Bitcoin scheme and optional label produced by the wallet. Read decoded fields instead of treating the QR image as a trust mark. A readable merchant name can be user-supplied metadata rather than verified identity.
Write the decoded fields beside the invoice rather than copying only the graphic. The full destination must be compared at more than the first and last characters. It cannot authenticate an invoice issuer, reverse a mistaken transaction or prove that the recipient's internal account has been credited.
Reject address changes between invoice and signing screen. Review the full address, requested amount, Bitcoin scheme and optional label produced by the wallet. A prefilled amount should match the invoice unit exactly. Write the decoded fields beside the invoice rather than copying only the graphic.
Check time and amount semantics
Confirm whether the invoice uses BTC or a fiat conversion, when the quote expires and whether partial payment is accepted. Keep network fees separate from the amount the recipient should receive. Price movement or a stale invoice can make the decoded amount different from the current obligation.
Refresh only through the authenticated invoice route, never a message link. A prefilled amount should match the invoice unit exactly. Approve only when the verified invoice and the final wallet display agree on destination, amount, network context and timing, then keep a minimal reconciliation record.
Retain a receipt without exposing unrelated wallet history. Confirm whether the invoice uses BTC or a fiat conversion, when the quote expires and whether partial payment is accepted. The wallet's final screen controls what will be signed. Refresh only through the authenticated invoice route, never a message link.
Review the final wallet screen
Compare the full destination, amount and network fee immediately before approval on the trusted device. Reject address changes between invoice and signing screen. Clipboard or interface substitution can occur after an earlier visual check.
Cancel on any mismatch and rebuild from the verified invoice. The wallet's final screen controls what will be signed. A QR code reduces typing but does not prove who created the invoice or what the wallet decoded. The final approval must compare the trusted merchant context, full address, amount and network with the wallet screen rather than relying on the square image alone.
Authenticate the invoice channel before scanning its code. Compare the full destination, amount and network fee immediately before approval on the trusted device. The receipt should preserve transaction and invoice identifiers only. Cancel on any mismatch and rebuild from the verified invoice.
Preserve a minimal receipt
Record invoice reference, transaction identifier, sent amount and time after broadcast. Retain a receipt without exposing unrelated wallet history. A full wallet screenshot may reveal balances, addresses and unrelated counterparties.
Share only the fields needed for reconciliation and never a seed phrase or private key. The receipt should preserve transaction and invoice identifiers only.

What the official source establishes
Bitcoin.org supports scan-and-pay use, user control of wallet keys, selectable fees and the public, permanent nature of blockchain transaction records.
What remains outside the evidence
It cannot authenticate an invoice issuer, reverse a mistaken transaction or prove that the recipient's internal account has been credited.
Close with a documented decision
Approve only when the verified invoice and the final wallet display agree on destination, amount, network context and timing, then keep a minimal reconciliation record.
Payment convenience does not make gambling safer. Adults 18+ should use affordable limits and never scan a rushed invoice to recover a loss.
