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.
I’ve got another sign with the finger pickup tomorrow. That’s only used at their Ship To pickup area for whatever reason. There is only the normal seasonal flu concern around here for now, but I’ll be using the Purell after I sign for my items, a couple of prepper items that had to be special ordered.
