If a user loses an electronic device that has the capability to conduct financial transactions, the user may report that the electronic device is lost using a lost-device software application to a management electronic device associated with a provider of the electronic device. In response to receiving this information, a disabling command is sent to a payment network associated with the financial account of the user to temporarily disable use of the electronic device to conduct the financial transactions. In particular, the electronic device may include a secure element that stores a payment applet for a financial account, and the disabling command may disable a mapping from a virtual identifier for the financial account to a financial primary account number. Subsequently, if the user finds the electronic device, the user may re-enable the capability (and, thus, the mapping) by providing authentication information to the electronic device.
