To check who your payment solution provider is, you can try the following steps:
1. Review Your Payment Terminal: Often, the name of the payment solution provider is displayed on the payment terminal or its packaging. Look for logos or branding from providers like Ingenico or others.
2. Check Your Merchant Agreement: Your merchant agreement or contract usually specifies the payment solution provider you are using. It may be included in the terms or under payment processing details.
3. Contact Your Bank or Acquirer: If you’re unsure, contact your bank or the acquiring institution that set up your payment processing. They should be able to tell you who the payment solution provider is.
