Business Card Security

Yori and Chou each have a set of business cards that key to the person they are given to. Only that person can see the information on the card; it appears blank to everyone else. If the numbers are read aloud anyone within hearing range hears a jumble and quickly forgets the incident. Yori is very selective on who gets one of her cards.
