What this tool checks
Five inputs, three plans
- Entry route — visa-free entry gives you a short runway; a visa application gives you a long one.
- Card networks — Visa, Mastercard, and JCB can link to payment apps; Amex and UnionPay stay POS-first.
- Verification status — unfinished real-name verification is the most common blocker, and it is much easier at home.
- Linking willingness — refusing to link a card rewrites the whole plan toward cash and card terminals.
- Trip length — longer trips need a bigger cash buffer and an eye on the USD 50,000 annual cap.
