METHOD AND APPARATUS FOR GENERATING PAYMENT TWO-DIMENSIONAL CODE

摘要

The embodiments of the present description provide a method and apparatus for generating a payment two-dimensional code; said method may comprise: receiving code information to be signed, said code information comprising an account identifier of a payment account bound to a two-dimensional code display device; if it is confirmed that a private key stored in a security chip is in an available state, then using the private key to sign the code information; the available state indicates that the private key has obtained a digital certificate; returning the signed code information to the two-dimensional code display device so that the two-dimensional code display device displays the code information as a two-dimensional code used for payment, the two-dimensional code comprising the account identifier, and the two-dimensional code changing dynamically.
