Patent attributes
This disclosure is directed, in part, to providing payment device security by storing security information in a payment device that, when received by a point-of-sale (POS) device, initiates a security request by the POS device that is used to protect the payment device against fraudulent use or misuse by unauthorized people. The payment device may store a code that, when received by the POS device, may allow the POS device to determine a security request associated with the code. The POS device may determine the security request by converting the code locally or the POS device may transit the code to a security provider that returns the security request. The POS device may then implement and/or enforce the security request. In some embodiments, the authorized user of the payment device may specify at least part of the security request, thereby enabling customization the security request.
