A practice payment review

A report arrived late. What did you know before it arrived?

You're checking a payment, but its device report is missing. Save a note, then add the report and see why your earlier review stays the same.

Step 1 of 3

The device report is missing

Information about this payment Not enough information

Evidence in this copy
Report	What we know
Device recognized	Missing
Locations differ	Yes
Attempts	5

We can't check every condition yet. The device report hasn't arrived, so we don't know whether the device is recognized.

Save what you know

Your note will stay with the information you have now. You can edit the example note.

How the example checks this payment

The example checks whether the device is unrecognized, the locations differ, and there are at least five attempts. All three conditions must match. The technical label "indeterminate" means there is not enough information to decide.

Why I built this

Canonical works with payment and device information. I built this demo to explore how someone checking a payment can understand missing information and keep a clear record of an earlier review.

This is an independent project using made-up information. It does not connect to Canonical's systems. More about this project
