Check Trip Documents Before You Book — Free
List each traveler, document expiry, destination rule to verify, and booking date so the passport check happens before payment. This guide treats trip documents as a physical working surface, so you can inspect the relationship instead of accepting a generic paragraph.
The proof surface
The ordinary version gives you a list. The wallet makes the missing relationship visible and leaves a named next step.
Why the flat version breaks
A flat checklist hides the decision that makes this job hard. For trip documents, the missing detail is not more advice; it is the relationship between the source, the measurable field, the date, and the note you will act on. The companion card keeps those layers separate and lets you change one input without rewriting the whole page.
Use the wallet in four passes
What breaks first
Empty or vague input
If there is no subject or note, the app leaves the card in an empty state and tells you what to add. It does not invent a result.
A number that does not fit
Negative, fractional, or oversized counts stay in the fields and produce an actionable input message. Check the unit before you rely on the number.
Outside facts
The local card organizes what you entered; it does not confirm a deadline, rate, rule, diagnosis, or booking. Keep the source beside the result.
Try the free wallet
The companion opens with the same sample shape, three starter records, a reset state, a copyable result, and a state link. Nothing is sent to a server.
Open the free trip documents card →Keep the work if you will use it again
Run the card repeatedly, edit the source, and copy the result without creating an account.
Printable document wallet with the same 4 records; estimate: 4 rows × ~3 minutes of formatting = ~12 minutes avoided. The paid tier extends the result; it does not remove the free core.
