Methods and apparatus for enabling a proximity payment device to generate dynamic data for securely conducting a transaction by emulating a magnetic stripe payment card. In an embodiment, a mobile device processor transmits information to a digital enablement service computer to activate a simulated magnetic stripe payment wallet application stored in the mobile device. The mobile device then receives one or more cryptographic keys, generates an unpredictable number (UN), generates dynamic CVC3 data based on the UN, and then assembles emulated magnetic stripe data. During initiation of a purchase transaction, the mobile device processor transmits the emulated magnetic stripe data to a communications interface associated with a merchant device.

A method for authorizing a digital wallet transaction initiated by a consumer from a merchant web site or app includes providing an acceptance mark on a merchant landing page associated with the merchant web site or app for initiating the digital wallet transaction, the acceptance mark comprising a link to a host server accessing an acceptance network for authorizing payment, the acceptance network comprising a plurality of digital wallets. A wallet selector switch allows selection of a wallet, the transaction is routed to the selected wallet, a payment card and shipping address are selected and the transaction is redirected back to the merchant with purchase details for authorizing and completing the digital wallet transaction. The wallets can include federated and non-federated cobranded wallets and partner-hosted wallets. Direct provisioning with partner credentials and automatic update of consumer details is provided in a federated cobranded wallet.
