Fully live: UAE — the deepest deployment, from malls to taxi QRs, and the corridor whose remittance costs just broke 3 percent; Singapore — PayNow linkage, instant both ways; Sri Lanka, Mauritius, Nepal, Bhutan — merchant QR coverage concentrated in tourist zones and expanding.
Acceptance mode: France — Eiffel-ticket beginnings, luxury retail following; select Gulf duty-frees.
Coming: Saudi Arabia's pilot (watch haj season), Qatar, Peru.
The mechanics travellers ask: transactions debit rupees at interbank-linked rates, typically beating card forex margins; daily caps mirror domestic limits; your existing app works — look for the local QR standard or NIPL acceptance mark.
The honest gaps: refunds cross-border remain slower than payments; acceptance outside tourist corridors thins fast.
