This article covers the latest “Must Have” free sample project for the GP Power Tools – Developer Tools module (requires Build 28 or later).
Back in 2012, I created code to obscure customer credit card details (see more information below). Using the same concepts, I have now created a project to obscure Bank Account Numbers for Checkbooks, Customers, Vendors and Employees.
Whether you have a requirement (see NACHA Security Requirements article) or not, best practice would be to make sure that Bank Account Numbers in your system are not human readable while stored in the database.
