Airwallex is moving into in-person payments. The move deepens its rivalry with Stripe across the payments stack, and enables the startup to directly aim at Square and Adyen on one of the last major battlegrounds in financial technology. The startup currently boasts close to 90 regulatory licenses across 70 to 80 regions, direct connections to local payment networks in over 120 countries, and the ability to settle transactions in more than 90 currencies.
