Micro-SD device loaded with a smart card
A Micro-Secure Digital (“SD”) device loaded with a smart card that can be issued in bulk and in card form is provided. The device includes: a SD interface electrically connected to a host terminal; at least one memory module; a SD controller connected to the SD interface to provide communication between a host terminal and the memory module; at least one smart card IC for data communication with the SD controller; and a smart card interface for issuing smart cards. Since the Micro-SD device is provided with a smart card function and a card form satisfying the ISO 7810 standard, it may be issued in bulk through automation using a conventional automatic card-issuing device that automatically issues a credit card or a USIM card.
1. A Micro-Secure Digital (“SD”) device loaded with a smart card, comprising:
a SD interface comprising a number of pads configured to be electrically connected to a host terminal in which the Micro-SD device is inserted, wherein said SD interface includes eight or more SD pads which are compatible with a Micro-SD standard and positioned at an end of a body of the Micro-SD device;
at least one memory module;
a SD controller connected to said SD interface to provide communication between the host terminal and said at least one memory module;
at least one smart card integrated circuit (“IC”) connected for data communication with said SD controller and comprising a security authority module; and
a smart card interface comprising a number of pads configured to be electrically connected to the host terminal, wherein said at least one smart card IC is configured to be accessed directly through said pads of said smart card interface, and wherein said smart card interface includes six or more ISO 7816 standard pads which are positioned in the rear of said SD pads;
wherein the Micro-SD device is configured to be detachable from an empty card having a size and a form that satisfy the International Organization for Standardization (“ISO”) 7810 standard of a plastic card so that it is automatically issued by a universal card-issuing device.
2. The Micro-SD device loaded with a smart card according to claim 1 , wherein the ISO 7816 standard pads include a power supply terminal, an initialization input terminal, a clock terminal, a grounding terminal, a program voltage terminal and a serial data input/output (“I/O”) terminal.
3. The Micro-SD device loaded with a smart card according to claim 1 , wherein said at least one smart card IC is configured to be accessed directly through the smart card interface and/or through the SD interface and the SD controller.
4. The Micro-SD device loaded with a smart card according to claim 1 , wherein the body of the Micro-SD device includes a shoulder for removal from the host terminal.
5. The Micro-SD device loaded with a smart card according to claim 1 , wherein the body of the Micro-SD device includes a groove for removal from the host terminal.
6. The Micro-SD device loaded with a smart card according to claim 1 , wherein said smart card interface is connected to a communication line between the SD controller and the at least one smart card IC.
7. The Micro-SD device loaded with a smart card according to claim 1 , wherein said smart card interface is connected directly to the at least one smart card IC.
