An apparatus and corresponding memory card holder wherein the apparatus includes: a casing configured to enable a plurality of memory cards to be removably inserted into the casing; contact pads located within the casing configured to enable an electrical connection to be established between the contact pads and at least one memory card when the plurality of memory cards are inserted within the casing; and at least one mounting portion configured to enable the apparatus to be mounted on a circuit board such that a first portion of the apparatus is positioned above the circuit board and a second portion of the apparatus is positioned below the circuit board.

The present disclosure relates to a method for obtaining music data, an earphone and a music player. The method includes: reading an identification code from a memory card; sending the identification code to a mobile terminal so that the mobile terminal sends the identification code to a server, and the server returns stored music data, corresponding to the identification code, to the mobile terminal; receiving a music signal converted by the mobile terminal after the mobile terminal obtains the music data from the server; and outputting the music signal.

Electronic devices are provided with ejectable component assemblies that can be substantially flush with the external surfaces of the housings of the devices, despite variations in their manufacture. The ejectable component assemblies may include connectors coupled to circuit boards of the devices, and trays that can be loaded with removable modules, inserted through openings in the housings of the devices, and into the connectors for functionally aligning the removable modules with the circuit boards. The ejectable component assemblies may also include ejectors coupled to the housings of the devices for ejecting the trays from the connectors and, thus, from the devices themselves.

A memory system is constituted of a file storage flash memory storing a control program required for a control portion and a large amount of data, and a random access memory storing a program used by the control portion and functioning as a buffer memory for received data. Thus, a memory system for a portable telephone capable of storing a large amount of received data at high-speed and allowing reading of the stored data at high-speed is provided.

Systems and methods for pairing a payment object reader with a computing device are described. An example method includes detecting, by a computing device and while in a pairing mode, a plurality of payment object readers. Each of the plurality of payment object readers is configurable to be paired wirelessly with the computing device. Each of the plurality of payment object readers outputs a signal strength representative of a location of the payment object reader relative to the computing device. The computing device tracks respective signal strengths of the plurality of payment object readers over time. Based on a determination that a change in a signal strength of a particular payment object reader of the plurality of payment object readers represents movement of the particular payment object reader relative to the computing device, a wireless communication channel is established between the particular payment object reader and the computing device.
