Episode 1345

Jonathan from Scottsdale, AZ
Eikon Mini Fingerprint Reader

Jonathan has a Windows laptop and he wants to add a fingerprint scanner. The one he's looking at works with WIndows Hello, but there's no real branding.

Wallace from Rancho Palos Verdes, CA

Episode 1325

Wallace took his computer into a repair shop, and now he's concerned that they could have put monitoring software on his computer.
