SAN FRANCISCO—Financial services giant Visa held a press event Tuesday to introduce "Visa Voice," a new line of talking credit cards that urges shoppers to just go ahead and buy it if that's what they really want. "Whenever you're near an item you're hesitant to purchase, Visa Voice offers words of encouragement, such as 'Come on, just go for it!' and 'Trust me—you're not gonna regret this,'" Visa president John Partridge said of the groundbreaking new payment product, which allows users to select between a calm, supportive female voice and a morally authoritative male voice. "If you're still not convinced after 30 seconds, the card will begin whispering, 'You know you want it,' and repeat the phrase a bit louder each time until cardholders have received the verbal reassurance needed to just say, 'Fuck it—I'm getting this.'" Partridge added that if customers exceed their credit limit, the card falls silent and quickly changes the subject.
