Abstract

Systems and methods are provided to allow for multifactor authentication of automatic teller machines (ATM) transactions and transactions at a merchant's point of sale. In an illustrative implementation, a secondary PIN request is delivered to participating users, and/or a one-time use, randomly generated secondary PIN to a customer's mobile phone via a text message when the customer initiates a transaction at an ATM. The customer then replies with a text message to the secondary PIN request with the customer's PIN or inputs the secondary PIN into the ATM before the transaction may proceed. In an illustrative implementation, the customer's mobile phone is allowed to be used as a mobile PIN terminal for various payments devices used at a merchant's point of sale system. Also, an additional level of customer authentication using the ubiquitous mobile phone can be allowed, thereby increasing the security of ATM transactions and non-cash payments.
