ATM/Debit Card Letter (Informative Version) - Core Conversion
A core conversion is great for many reasons, like allowing you to offer new services to account holders. This template will help keep account holders informed about the core conversion and how it will affect your ATMs and debit cards.

Dear [Customer’s/Member’s First Name],

We are excited to announce that we are converting to a new core banking system starting on [INSERT DATE] through [INSERT DATE]. We decided to change our core system so we may continue to provide you with safe, secure products and services all while utilizing the newest technology.

During our core conversion process, we will also update our ATM software, which will slightly affect your [INSERT FINANCIAL INSTITUTION’S NAME] debit card. Below is a summary of what to expect.


We will be updating our ATM software during the core conversion on [INSERT TIME AND DATE OF ATM UPDATE]. This will only affect the ATMs at our branch locations.

While our ATMs will be down on [INSERT DATE], you can always use [INSERT NAMES OF OTHER FINANCIAL INSTITUTIONS WHERE ACCOUNT HOLDERS CAN USE DEBIT CARD FOR FREE] ATMs surcharge free. Then, come back on [INSERT DATE] to check out our ATM’s new look.

Debit Cards

You will not be receiving a new debit card or PIN, and your debit card will continue to work during the core conversion process. It will, however, have a few limitations. One limitation is you will have limited access to our ATMs (noted above). You will also have limited access to your funds starting on [INSERT DATE] to [INSERT DATE].

Please also note that if you exceed your debit card or ATM withdrawal limit during the core conversion, your transaction will be denied. If you are denied, you may run your debit card as a different point of access, like a credit.

We are looking forward to the new changes, and we hope you are too. If you have any questions, please contact us at [INSERT PHONE NUMBER] or visit our website at [INSERT WEBSITE URL – OR SPECIFIC CORE CONVERSION FAQS PAGE ON YOUR SITE].
