The contents of this document discuss the minimum system requirements for the eTeller Check21 system with the currently installing versions:

  • Teller Capture workstation v4.1.11

As part of your project, specific requirements will be identified that take into account your organization’s needs.

"Minimum Requirements"

The term minimum requirements should not be construed as the specifics required for your systems to run correctly. In the absence of all other factors (e.g. other software running on the system or the processing volume of your Fl), the minimum specs are operationally valid. Ensure you factor in any additional software’s minimum specs and added resources to this server’s configuration as is appropriate. If you have questions, contact your IMM project manager or installer.


Environments must meet the minimum published requirements to qualify for Support. If you have questions about this, please ask prior to your installation dates.
