A1 or A3? Which one should I choose if I travel a lot between countries in the Americas?

The A1 is a file installed on your computer or in the cloud. You can access it from wherever you are—great for those who travel across the continent. The A3 is on a card or physical token that you need to carry around. For those who cross borders and work from several places, the A1 is usually more practical. TF inter helps you decide based on your routine and even handles the installation, so you don't get stuck in the middle of a negotiation abroad.
