Abstract
Disclosed are various embodiments for implementing secondary verification of user accounts through the use of near field communication devices. A first account code and first verification code are stored in a memory accessible to a computing device, wherein the first account code is associated with a payment instrument. A second account code is received in a charge request from a transaction client. A second verification code is further obtained from a client device. A determination is made as to whether to approve charging of an account based at least on whether the second verification code received in the computing device matches the first verification code.
