Corelation KeyStone


Core conversion

This is your headquarters for all things regarding the Technology Platform Update!

The core processing system is the computer software and supporting hardware we use to maintain member deposit and loan accounts, process transactions, support services such as Debit Cards and Online Banking, and more.

Credit Union 1 is committed to progressing with the best quality products, services, and technology. It is necessary for us to upgrade our core processor, and Credit Union 1 has selected Corelation KeyStone as our new processing provider. 

The conversion will take place October 1, 2021.

At the same time as the core conversion, CU1 will be migrating to a new online/mobile banking platform, Q2.


About KeyStone

Corelation’s KeyStone has been designed from its beginnings to be focused on the members and their relationships with the credit union. Not only is the user interface intuitive and easy to learn, our team will be able to serve members more efficiently by viewing the entire member relationship from one screen. KeyStone is built to be open and easily integrate with other technologies as well as evolve with advancements.
