Amazing product! Great Service!

From the day we met with Mendel… He was very honest and true to his word.. We couldn’t of asked for a better person to take care of our account.
He is very proactive and explains in detail the new system with Cardknox. He’s always there to answer any questions. Mendel gets 6 stars!!
Truly happy with our decision we made to switch to this wonderful company!
They have great competitive fees and a wonderful platform to help your business grow and extract valuable information.

Crashes, no support

The application refuses to open under the current operating system available for the iPhone 13. Clicking the app support link on the App Store takes you to a webpage with the 404 error. Waste of time.
