Limiting access to account information during a radio frequency transaction

1. A method, comprising:

generating, by an issuer computer, a secondary transaction code (STC), wherein the generating the STC comprises:

generating a random number,

determining whether the random number is available for use, and

in response to a determination that the random number is available for use, appending a product identifier number to the available random number such that the STC has a format equivalent to a transaction account code format;

associating, by the issuer computer, the STC to a transaction account code;

issuing, by the issuer computer, a transaction account associated with the STC and an available account balance;

assigning, by the issuer computer, the STC to an RF transaction device;

submitting an RF transaction authorization request from a merchant computer to the issuer computer, wherein the RF transaction authorization request includes a request that the issuer computer return to the merchant computer the STC associated with the transaction account code;

receiving, by the merchant computer, an authorization record from the issuer computer in response to the RF transaction authorization request, wherein the authorization record includes the STC; and

storing a transaction record of the RF transaction in a merchant database, wherein the transaction record includes the STC.

2. The method of claim 1 , further comprising submitting a processing request from the merchant computer to a transaction processing entity, wherein the processing request includes the STC.

3. The method of claim 1 , wherein the merchant computer does not maintain a copy of the transaction account code in response to the receiving the authorization record that includes the STC.

4. The method of claim 2 , wherein the transaction processing entity receives the STC to facilitate a settlement of the RF transaction against the available account balance.

5. The method of claim 1 , further comprising associating conditions-of-use parameters with the STC at the merchant computer, wherein the conditions-of-use parameters place limits on how the STC may be used.

6. The method of claim 5 , further comprising receiving the conditions-of-use parameters from an account holder during the RF transaction.

7. The method of claim 5 , wherein the conditions-of-use parameters comprise at least one of an STC credit limit, an expiration date, a per purchase spending limit, a time of day use, a geographic location, a time of week use, or a specified merchant requirement.

8. The method of claim 1 , wherein the RF transaction device and the RF reader mutually authenticate to initiate the RF transaction.

9. A system, comprising:

an issuer computer comprising a processor and memory communicatively coupled to the processor storing instructions that in response to being executed, cause the processor of the issuer computer to perform operations comprising:

generating a secondary transaction code (STC), wherein the generating the STC comprises:

generating a random number,

determining whether the random number is available for use, and

in response to a determination that the random number is available for use, appending a product identifier number to the available random number such that the STC has a format equivalent to a transaction account code format;

associating the STC to a transaction account code,

issuing a transaction account associated with the STC and an available account balance, and

assigning the STC to an RF transaction device;

a merchant computer comprising a processor and memory communicatively coupled to the processor storing instructions that in response to being executed, cause the processor of the merchant computer to perform operations comprising:

communicating an RF transaction authorization request to the issuer computer, wherein the RF transaction authorization request includes a request that the issuer computer return to the merchant computer the STC associated with the transaction account code,

receiving an authorization record from the issuer computer in response to the RF transaction authorization request, wherein the authorization record includes the STC, and

storing a transaction record of the RF transaction, wherein the transaction record includes the STC.

10. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, in response to execution by one or more computing devices, cause the one or more computing devices to perform operations comprising:

generating, by an issuer computer, a secondary transaction code (STC), wherein the generating the STC comprises:

generating a random number,

determining whether the random number is available for use, and in response to a determination that the random number is available for use, appending a product identifier number to the available random number such that the STC has a format equivalent to a transaction account code format;

associating, by the issuer computer, the STC to a transaction account code;

issuing, by a the issuer computer, a transaction account associated with the STC and an available account balance;

assigning, by the issuer computer, the STC to an RF transaction device;

submitting an RF transaction authorization request from a merchant computer to the issuer computer, wherein the RF transaction authorization request includes a request that the issuer computer return to the merchant computer the STC associated with the transaction account code;

receiving, by the merchant computer, an authorization record from the issuer computer in response to the RF transaction authorization request, wherein the authorization record includes the STC; and

storing a transaction record of the RF transaction in a merchant database, wherein the transaction record includes the STC.

11. A method, comprising:

generating, by an issuer computer, a secondary transaction code (STC), wherein the generating the STC comprises:

generating a random number,

determining whether the random number is available for use, and

in response to a determination that the random number is available for use, appending a product identifier number to the available random number such that the STC has a format equivalent to a transaction account code format;

associating, by the issuer computer, the STC to a transaction account code;

receiving, by the issuer computer, a radio frequency (RF) transaction authorization request from a merchant computer, wherein the RF transaction authorization request includes a request that the issuer computer return to the merchant computer the STC associated with a transaction account code assigned to an RF transaction device by the issuer computer;

issuing, by the issuer computer, a transaction account associated with the STC and with an available account balance;

transmitting an authorization record from the issuer computer to the merchant computer in response to the issuer computer authorizing the RF transaction, wherein the authorization record includes the STC;

submitting the RF transaction for processing in response to the transmitting the authorization record from the issuer computer to the merchant computer; and

storing a transaction record of the RF transaction in a merchant database, wherein the transaction record includes the STC.

12. The method of claim 11 , wherein the issuer computer decides conditions-of-use parameters associated with the STC.

13. The method of claim 11 , further comprising receiving conditions-of-use parameters from an account holder associated with the RF transaction device.

14. The method of claim 11 , further comprising billing an RF transaction amount against the available account balance associated with the STC.

15. The method of claim 14 , wherein the available account balance includes at least one of a monetary value, a credit value, a loyalty points value, or a reward points value.
