Write a claim that can be checked.
Replace “this wallet works on mobile” with a complete sentence: this model can perform this task using this app on this phone platform. Add the installed firmware if it changes the answer. Setup, signing and updating are separate claims, even when they happen in the same application.
For example, Nano X Bluetooth signing on iPhone does not settle the starting version required for Bluetooth OS updates. SafePal S1 QR signing does not remove its documented computer update requirement. Keep those conditions in your notes instead of compressing them into one compatibility tick.
Use each source for the question it can answer.
A model-specific support guide is useful for required equipment and supported steps. A product page helps identify the device and advertised features. A video may show the interaction, but check the model, app, operating system and recording date before treating it as a demonstration of your own setup.
An owner report can reveal a question to investigate, such as a pairing problem or a difficult screen. One report cannot establish how often it happens. Look for a reproducible description and a current official response without assuming the creator or commenter represents every buyer.
Keep missing evidence visible.
Use three labels in your private shortlist: documented, conditional and unresolved. A conditional answer includes the requirement that must be met. An unresolved answer means you have not found sufficient evidence, rather than that the product definitely cannot do the task.
Tangem’s NFC guidance illustrates why specificity matters: a phone may scan a card yet have limitations around backup creation. A general NFC feature list cannot settle that distinction. If an exact model is absent from the guidance, ask support rather than borrowing a similar handset’s answer.
Make a decision from the evidence you actually have.
Save the source URL, date checked and relevant condition beside each requirement. If two official pages disagree, record both and ask which applies to your intended workflow. Do not silently choose the more convenient answer, especially when the difference determines whether you need another device.
Open the product profile only after that evidence has narrowed the choices. Its official purchase link is the next step, not proof of compatibility. Recheck the app and required equipment before checkout; this method helps organise a decision without claiming that any device has been hands-on tested by us.
