How to create an Attendance Rooster and create scan number

Need help I need to create an attendance spreadsheet that I can use through this app. Can you make a Video on YouTube how to create attendance list. Also how to create a scan number. I like it that I might be able to just scan a number and it will help take the attendance. Please need this asap Thx :D
