In 2026, the general consensus for tourists is to leave your physical passport in a secure hotel safe and carry a high-quality digital copy or a physical photocopy instead. Carrying your original passport on the street increases the risk of loss or theft, which can be a nightmare to resolve at an embassy. However, there are exceptions: some countries (like Japan or Spain) legally require foreigners to carry official identification at all times, and a "passport card" or a national ID is often acceptable. For those in 2026 utilizing "Digital Nomad" visas or tax-free shopping, you may need your original passport at the point of sale to process VAT refunds. A good middle ground is to use a digital wallet on your phone to store a verified scan of your passport, while keeping the physical book locked away unless you are crossing a border or checking into a new hotel.
