Two countries, two of everything.

The situation

The set you use twice a year.

The accounts from the country you left are the ones you forget: a bank you touch in December, a pension portal, a landlord's letter you must answer in a language you half-remember.

Rarely-used logins are the most likely to be lost, and the hardest to recover from a distance, the recovery process usually assumes a phone number you no longer have.

Keep the rare set on a card and it stops being a research project. You read it, use it, and put it away.

A shape that works

One card per country.

1. I

   Here

   Daily things: current bank, current phone, current email.

2. II

   There

   The old set: bank, pension, tax number, an address that still receives post.

3. III

   Notes matter more

   For the rare set, write the small detail: which email it is under, which number.
