A kiosk for accepting a portable electronic device from a client in exchange for payment includes a display, one or more cameras, a portable device receiving arrangement, a payment dispensing arrangement, and a communication connection to a remote server and/or operator. The kiosk is configured to, in conjunction with the remote server and/or operator, control an application program executing on the portable electronic device and one or more the cameras to detect characteristics of the portable electronic device. The kiosk is also configured to determine a value for the portable electronic device based upon aspects including the detected characteristics, and to display the determined value on said at least one display for approval by the client. Subsequently, based upon the determined value, the kiosk provides a payment to the client via the payment dispensing arrangement, and deposits the portable electronic device in the kiosk for subsequent collection.
