Since the chips are marked on the backside it's easy for the magician to control these. So only one perdiction is neccessary "I will be holding the red chip. - You will be holding the blue chip. - The gold chip will be in the wallet." The gold chip has to be placed in the wallet; if the magician has the red one, he'll take the card an reads it, if the other person has the read one, she/he has to read.

Tell mum I like the new hair color 😊
