Thunder POS is proud to offer optional integrated credit card and ACH payment processing with our iPad, web-based, and Windows registers. If you are looking to sign up for processing services that can be integrated with your point of sale, check out our partners at Global Payments.
Also available for our users is an integration to Stripe Terminal, including support for many non-US Dollar currencies as well as support for Canadian Debit. This requires a Stripe account and terminal purchased from them.
