The trip
Be unremarkable.
Most travel advice is really about attention. A device that looks valuable invites questions; a card among cards does not.
MI8OS asks nothing of the places you pass through. No roaming data, no sign-in over hotel Wi-Fi, no service that has to be reachable from where you are standing.
The practical decision is not technical, it is logistical: which copy travels with you, and which stays home.
Before you go
A short packing routine.
-
I
Take one card, not three
One copy travels. The others stay in the places you chose. Losing the trip copy costs you nothing but a rewrite.
-
II
Trim the trip vault
You can write a smaller vault for travel: only the secrets you might genuinely need away from home.
-
III
Separate card and phone
Different bag, different pocket. One thing being taken should not hand over both halves.
-
IV
Rehearse once
Read the card on your phone before you leave, so the first time is not in an airport at midnight.
The safest luggage
looks like everyone else's.
