No pen or stylus at one Walmart I patronize. You just trace your name on the pad with your finger.
And there are the credit card payment key pads at checkout. Definitely need the hand sanitizer after using those.
We use the touchpad pens (also available at Walmart...lol...in the electronics section) for signing for ANY packages, CC charges, and signing touchpad screens.
We then wipe off pen with disinfecting wipe.
