The present invention relates to a smart card reader, and to a smart card reader to reduce the size and increase portability by applying a rotary card guide.

A smart card reader is a device that connects a host computer and a smart card and exchanges data with each other. A smart card is an electronic card with a built-in microprocessor, operating system and secure storage. Magnetic cards, which are widely used in the past, can be duplicated, but smart cards can not be duplicated and have high security. In addition, the user can safely store various secret information in the storage space inside the smart card. Smart cards are credit cards, cash cards and transportation cards. Used for identification. In addition, it stores securely the necessary certificates when using internet banking and can be applied to the authentication token for user authentication. Many years ago, the use of magnetic credit cards has been duplicated, causing a surge in damages. The government and financial institutions are pushing to replace existing magnetic credit cards with smart cards. Smart cards can be used in a wide variety of fields, such as the High Pass of the Road Corporation, T-money, a Seoul transportation card, an electronic passbook, an electronic passport, and an electronic driver's license.

To use a smart card, a smart card reader that connects the host computer and the smart card is required. In general, the size of a smart card is 85.6mm wide and 54mm long. Due to the size of the smart card, a smart card reader that is generally used has a size of at least 54mm, which is inconvenient to carry. Due to these limitations, there is a problem in that smart cards are difficult to use in applications requiring portability. In fact, the government and banks, including the government is trying to spread smart cards, but smart card readers that are inconvenient to carry smart card is severely limited to spread and use. In order to overcome this disadvantage, there is an invention of Korean Patent Application No. 10-2008-0013388. The present invention is characterized by securing the portability by reducing the size of the USB smart card reader by applying two folding card guides in order to overcome the disadvantages of the conventional smart card reader inconvenient to carry.
