Welcome to the Seller Community @Tmozdy, I noticed it's your first post!
You can enable magnification on your Square Terminal by following these steps:
1. On your Square Terminal, tap More >Settings > Hardware.
2. Tap Accessibility > toggle Magnification on.
3. Tap the back arrow to save.
Once you've enabled this, you can triple-tap on the screen to zoom in. While this zoom function won't be available on the signature screen, you can actually disable signatures, as they're no longer required for card purchases. Learn more on disabling signatures here, and thank you for this question!
