Commands similar to the following don't work:

scoreboard players set @e[name=click] click 1 {Equipment:[{id:minecraft:paper,Count:1b,Damage:0s,tag:{display:{Name:"Bandage"},Unbreakable:1,HideFlags:4}}]}

And this is what you get in the command block log, though the armor stand does have the property that suits the command.
