Abstract: An electronic apparatus is designed for interacting with an external device. The external device stores data like photos, document and/or data streams. The electronic apparatus includes a transmission interface, a detector and a processing circuit. The detector detects whether the external device is within a predetermined distance from the electronic apparatus, e.g. direct contact or within a distance. Besides, the external device is not wire connected with the electronic apparatus. The processing circuit automatically performs a data connection with the external device when the detector detects the external device within the predetermined distance.
