Abstract

Technology is provided for using a mobile device as part of a payment system. The mobile device utilizes an accessory with a security feature based on its connection state to the mobile device. When the accessory detects disconnection, the accessory deletes user account information on the accessory. When in a valid connection state, the accessory transmits a user payment service account identification and an accessory identification to a transceiver of a merchant computer system to initiate a transaction. A payment service system eventually receives the information transmitted by the accessory, and contacts the mobile device associated with the account for transaction approval in one example. Thus, the user initiates the transaction at his/her mobile device using the connected mobile device accessory, and approves the transaction on his/her mobile device. In other examples, the user can send approval in a transmission to the merchant system or set up other pre-authorization criteria.
