A mobile terminal further comprises: a case having an opening formed therethrough so as to communicate with the inside thereof; and a card tray inserted in the opening, wherein the card tray further comprises a cover part for covering the opening; a support part positioned inside the opening and comprising a seating part on which a card is stably placed; and a flexible part connecting the support part and the cover part and fitted/coupled to the circumference of the opening. The mobile terminal wherein the relative position of the cover part to the support part changes with morphological changing of the flexible part allows the positions of the cover part and the support part in the card tray to be flexibly variable. Therefore, even when positions of the opening and a card socket are mismatched, a card can be mounted in the mobile terminal, thus reducing an initial detective rate and an operationally detective rate.

A payment object reader configured to delay reading data of an integrated circuit payment object in the payment object slot of the payment object reader until the rest of the payment object reader is ready to read data off of the integrated circuit payment object. The payment object reader can be configured to include a microcontroller configured to monitor and manage the payment object contact switch and the integrated circuit payment object interface of the payment object slot of the payment object reader.

A connector component for use in an electronic device for concurrently accepting multiple forms of data storage cards. The connector component comprises a housing shell, a housing shell support, a plurality of contacts, and a tray. The housing shell support includes a flexible bilateral surface with a first side that is coupled to the housing shell. In response to a force from an inserted data storage card, the housing shell support temporarily recoils, thereby decreasing an area between the housing shell and the housing shell support. The plurality of contacts is coupled to an exposed surface of the housing shell support. The plurality of contacts interconnects with a corresponding electrical contact on each inserted data storage card for electronically transferring electronic data. The tray has a capacity to hold at least three different forms of data storage cards for a concurrent insertion into a cavity of the connector component.
