Combatting Identity Theft (Score 2, Insightful)

Although identity theft is much broader than just unauthorized usage of credit cards wouldn't it seem logical to force a PIN number to be used for all credit card transactions. It seems that the majority of vendors already have the equipment and capacity to allow a customer to enter a PIN for Debit. Why not integrate this into credit transactions? This would be especially helpful for people who may have lost their card or if someone has copied the number. RickP
