Devices, systems, and methods are disclosed which relate to using a remote scanner for mobile transactions. A point of sale (POS) terminal communicates with a remote scanner that is removably coupled to the POS terminal. Logic on the POS terminal generates a request for a transaction information and transmits the request along with a restriction to the remote scanner. Logic on the remote scanner receives the request and the restriction, transmits the request to a mobile device, receives the transaction information while monitoring the restriction, and transmits the transaction information to the POS terminal for processing. The transaction information may be provided subject to the restriction.
