It brings a flexible solution which uses all existing communication channels such as SMS, IVR, IVVR, USSD and Email. CaaStor enables Mobile Payment and Mobile Money services using any Mobile Phone even basic ones and doesn’t require specific or expensive Smartphones. The great advantage of CaaStor is its ability to connect to multiple Operators simultaneously, host services for multiple Banks and interact virtually with any Mobile handset brand.


CaaStor™ services can be highly customized using a simple yet versatile web based scripting tool, allowing unmatched flexibility in designing rapidly step by step interactive USSD, SMS and voice/video services. Services can retrieve, use and store data from external content servers/content providers, such as customer bank data.
