Method for a microchip card with a USB interface

Disclosed is a method for a microchip card with a universal serial bus (USB) interface. Benefits include improved functionality, improved usability, and improved cost effectiveness.

Background

        � � � � � The popularity of the Internet and cashless payments has made the use of credit cards very popular. A fast and simple digital signature technology increases security and convinces people to better utilize Internet resources.         �

        � � � � � Keyboards with card readers are widely used in banking systems but are not popular for home use, partly due to their expense.

        � � � � � Microchip cards are also used for electronic authorization. They are considered more secure than magnetic cards. As a result, they are used for public phones systems and digital signatures in many countries. Some microchip cards have a magnetic stripe for compatibility with old card devices.

General description

        � � � � � The disclosed method is a microchip card with a USB interface. The standard credit card dimensions are unchanged. The interface connects the microchip on the card and a PC. The functionality of microchip card is not limited in any way. Alternatively, the RS232 serial protocol could be implemented.

        � � � � � The microprocessor on the card is powered by the PC through the USB interface. Standardizing the USB connector on the microchip card makes the technology affordable and easy to implement.

Advantages

        � � � � � Some implementations of the disclosed structure and method provide one or more of the following advantages:

•        � � � � Improved functionality due to providing a standard interface between a microchip card and a PC�

•        � � � � Improved usability due to the widespread availability of USB ports and cables

•        � � � � Improved cost effectiveness due to the low-cost to implement the interface connector in the card

Detailed description

        � � � � � The disclosed method is a USB connection between a microchip card and a PC (see Figure 1). The microchip card has a microchip and, possibly, a magnetic stripe. A connector is placed in the corner of the card. The card is a standard credit card size. It is, basically, rectangular (see Figure 2). The reverse side of the card may contain a magnetic stripe (see Figure 3).

        � � � � � One corner, designated as D, contains the exposed microchip card interface connector. A connector is placed on both the front and the back of the card. Corner D becomes a plug-in that is placed in the special socket. It acts as an interface between the USB cable and the card...
