Secondary verification

A system, comprising:

• at least one computing device;
• at least one memory accessible by the at least one computing device, the at least one memory having stored thereon a first account code, a first verification code, and a verification application;
• and
• the verification application executable in the at least one computing device, the verification application comprising:
• logic that obtains a second account code from a charge request received from a transaction client, wherein the second account code is obtained by reading a first near field communication device that embodies the second account code at the transaction client, the second account code being associated with a payment instrument that includes the first near field communication device;
• logic that obtains a second verification code, wherein the second verification code is associated with a second near field communication device;
• and
• logic that determines whether to approve charging an account associated with the charge request received from the transaction client based at least upon whether the first account code matches the second account code, and the first verification code matches the second verification code.

A method, comprising:

• storing, using at least one of one or more computing devices, a first account code and a first verification code in at least one memory;
• obtaining, using at least one of the one or more computing devices, a second account code from a charge request received from a transaction client, wherein the second account code is obtained by reading a first near field communication device that embodies the second account code at the transaction client, the second account code being associated with a payment instrument that includes the first near field communication device;
• obtaining, using at least one of the one or more computing devices, a second verification code, wherein the second verification code is associated with a second near field communication device;
• and
• determining, using at least one of the one or more computing devices, whether to approve charging an account associated with the charge request received from the transaction client based at least in part upon whether the first account code matches the second account code, and the first verification code matches the second verification code.
