The Tag can Appear, Change & Vanish

The strolling magician approaches a group of people.
They notice his name tag has been left blank.
"No problem", says the magician and with a wave of his,
hand his name actually appears printed boldly on the tag!
Or
You approach a table wearing your name tag.
You have a card selected from a deck.
You wave your hand over the tag and your name changes to the name of the selected card!
Or
Your name appears on the blank tag and then later the tag vanishes completely,
leaving a spectator's signed card in its place....and this is just the beginning!
