You can select “enter PCGS barcode” and manually enter the barcode info into the program. If it finds the info great - if not you have to just use the add coin feature.
I use a $35 bar code scanner from Amazon. I have a lot of coins to enter and most do not scan - the scan adds extra info. Too bad they don’t have good support - might be time to find a better supported. Too bad because I like the program.
