[thingsinherited]

Greetings, I some something for pickup only. Someone is coming to get it and is supposed to have a 6 digit code for me to enter to show that it was picked up.

  I use a desktop computer hooked to my TV..

  Where will I enter the code number? I can't seem to find an answer.

  My camera skills regarding a QR code are limited.
