Finding Your Credit Card Terminal Serial Number

Modified on Thu, 16 May 2024 at 03:18 PM

Overview

Credit card readers have unique serial numbers that are found underneath them.  We don't maintain a current record of serial numbers as devices may be exchanged occasionally. To ensure accuracy, we request that you provide us with this information for the card reader(s) you wish us to troubleshoot or configure since this has to be paired correctly to your POS and Back-office. 


Step 1. Remove the card reader from the mount.


Please click this link to view the steps on how to detach your card reader from your mount. While this article pertains to the s300 model, the steps should generally apply to all models.


Step 2. Look for the sticker that has "S/N" on it.


Please refer to the pictures below for the specific model of your card reader.
