Payment processing is an important (arguably the most important) part of online transactions. In this article we'll talk about how we handle payment processing, and different payment processors. This article may be broadly applicable to POS systems outside of CounterPoint.
The Modern Retail integrator does not actually interact with any credit card or payment information during the transaction process. It's designed this way to help ensure your site's security, and the security of your customers.
This means that (for the most part) changing payment processors will not affect your integration. You may want to get in touch with us first, just to be certain, but broadly speaking switching between different payment processors will not negatively affect how your integration works.
