A system for staging and executing secure, service-based, transactions. The transactions are staged by a mobile device. The system may include a receiver. The receiver receives a communication from the mobile device in order to stage a transaction. The system may also include a near-field communication (NFC) device mounted in the CSC. The NFC device may communicate with the receiver. When the receiver receives a pre-staging communication, the receiver sets the NFC device to a staged state. In the staged state, the NFC device performs an NFC handshake with the mobile device. Following the NFC handshake, the receiver receives a signal from the mobile device. The signal includes a biometric confirmation of the identity of the user and an identification of the mobile device. The biometric confirmation may be derived by the mobile device from a biometric parameter associated with the user. The handshake initiates completion of the transaction.
