I'm not sure what you mean by "digital bank." All banks store and move money digitally (electronically), most have web sites and apps. I think you mean the distinction between an actual (regulated, insured) bank and a company offering some bank-like financial services such as PayPal, Wise, Revolut, etc.<p>The best bank for someone who travels a lot without a fixed home base will charge no foreign transaction fees, no ATM fees (or reimburse ATM fees), 24/7 real person customer service (not a chatbot or FAQ or Twitter), insurance on deposits, and operate within a regulatory framework that offers protection from having your account locked or closed with no recourse, or deposits held unreasonably long with no explanation (Square, PayPal).<p>All reputable banks of any size can send and receive money electronically, either through their own tools or with digital wallets, or with Zelle or Wise or Venmo.<p>For US citizens/permanent residents I recommend Charles Schwab, the investor checking account. No fees, ATM fees reimbursed, 24/7 human customer service that actually deals with issues. Schwab gets recommended a lot by nomads. Citibank has a similar account, not sure what they call it. For people with citizenship or permanent residency in other countries I don't know the best bank but you can find discussions online in the many nomad forums.<p>As a long-time nomad (US citizen) with no home base anymore I use Schwab and have a backup account at a US credit union, along with several credit cards that have perks for travel. I use ApplePay more and more. I use Wise for moving money from one country to another, but I don't keep money in my Wise account. I tried Revolut, but too many fees, too many restrictions on number and amount of ATM withdrawals, online-only support, etc. made me drop it.<p>I suggest using credit cards and virtual card numbers when making purchases online or abroad, never use a debit card except at an ATM in a secure place (like inside a bank lobby). For Americans at least canceling unauthorized charges or getting a card canceled and reissued is much easier with a credit card versus a debit card. Think about what would happen if your Wise or Revolut card got stolen, or skimmed, or copied by a restaurant server. Banking problems while traveling can get expensive and frustrating.
