====== Merchant Warehouse (Cayan) ======



Merchant Warehouse is a previously supported online credit card processing merchant for Cyrious Control. 
  * Beginning with Control 4.4 and SMS 8.9pci, the Elavon interface is the only interface that is PCI-DSS (PA-DSS) certified.
  * Beginning with Control 5.5, there is no longer an option available in the program to be able to use Merchant Warehouse as their credit card processor. 
  * Merchant Warehouse is now known as Cayan

**Please Note**: Any company that is currently using Merchant Warehouse as their processor will need to setup an account with Capital Q before they are updated to ensure that they do not lose the ability to process credit cards. There is a web portal listed below as a temporary solution for companies that need to be able to process cards but have already been updated to version 5.5 or above of Control.
