Real-World Example
Jane scans a QR code or opens a signed payment link from a creditor message. The portal should take her directly to the intended payment context while still protecting the link from tampering or misuse.
Visual Flow
How It Should Work
- It should validate signed external payment links before showing payment details.
- It should route the consumer to the intended account and payment context.
- It should support QR-code entry points without bypassing account safety.
How It Should Not Work
- It should not accept expired, modified, or unsigned payment links.
- It should not expose full portal access to a link viewer unless normal authentication allows it.
- It should not let one signed link pay a different account.
