Description

A DONGLE DEVICE WITH COMMUNICATION MODULE FOR A SECURE ELECTRONIC TRANSACTION
CROSS REFERENCE TO RELATED APPLICATION
[0001] The present application claims the benefit of an Indian Provisional Patent Application entitled, "SYSTEM AND METHOD FOR SECURE ELECTRONIC TRANSACTION" with serial number 3415/CHE/2011, filed at Government of India Patent Office on October 3, 201 1, the content of which is incorporated by reference herein.
BACKGROUND
Technical field "
[0002] The embodiments herein generally relate to a field of electronic transaction. The embodiments herein particularly relate to a dongle device for an electronic transaction and more particularly relates to a dongle device with communication module for a secure electronic transaction.
Description of the Related Art
[0003] Currently, there are hundreds of magnetic stripe readers/s wipers on the market and all of them are at least as long as the credit card itself. There exist different types of card readers/swipers. One type of a card reader is a traditional card swiper with a single rail, which allows a card to be held against a base of the reader by the user and moved across the read head of the reader. Another type of a card reader guides a card by the two sets of rails and a backstop. Once the user has inserted the card against the backstop, the card is read as it is removed from the swiper. The magnetic stripe cards having standard specifications can typically be read by the point-of-sale devices at a merchant's location. When the card is swiped through an electronic card reader at the checkout counter at a merchant's store, the reader usually uses its built-in modem to dial the number of a company that handles the credit authentication requests. After the account is verified, an approval signal is sent back to the merchant to complete a transaction.
[0004] The conventional swipe device using the magnetic card readers for an electronic payment is bulky. Further the merchant has to produce the printed receipts for the customer, which is very cumbersome for the merchant handling the multiple customers. Still further, the merchant has to keep record of all the printed receipts, to avoid a dispute about the transactions. It is advantageous for an individual to make a payment to another individual or merchant by swiping his magnetic stripe card through a reader connected to a mobile device. The mobile device should include a communication medium such as GPRS, WiFi, Bluetooth, etc., to transmit the card data to the server. Further the mobile device should be carried everywhere.
[0005] As a result, there were huge developments in providing the card reader for a mobile device. In the currently available systems, a portable swipe machine for the mobile devices is provided and the card data is encrypted on the mobile device. Hence there is a chance of an insecure transaction over the mobile device. Further, the existing systems communicate a relevant data through the electrical signals, which are extremely slow compared to the electromagnetic signals. In the current scenario, the communication is always performed on IP network, since IP networks are wide spread. Further the existing devices work only with the high end devices such as iPhone, iPad or any other smart phone, thereby making the system very costly for the prospective users. Further the currently used swipe machines are active devices, in which the machines need to be charged with an external power supply or through a connected device.
[0006] In view of the above facts, there is a need for a dongle device with a communication module to carry ut a secure electronic transaction. There is also a need for a system and method for providing a secure electronic transaction in a cost effective manner. Further there is a need for a system and method to enable a fast, efficient and secure electronic transaction by using a dongle device. Yet there is a need for a system and method to utilize the fast and efficient IP communication, thereby reducing a need for the use of an electrical signal.
[0007] The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
OBJECTS OF THE EMBODIMENTS
[0008] The primary object of the embodiments herein is to provide a dongle device for a secure electronic transaction.
[0009] Another object of the embodiments herein is to provide a dongle device with a communication module for a secure electronic transaction. [0010] Yet another object of the embodiments herein is to provide a dongle device to connect directly to a server or a payment gateway to perform a secure electronic transaction.
[001 1] Yet another object of the embodiments herein is to provide a method to transform a card data into a token data and to transmit the token data without sending the card data from a computing device to a server.
[0012] Yet another object of the embodiments herein is to provide a method for converting the card data into an audio data at supersonic frequencies.
[0013] Yet another object of the embodiments herein is to provide a method for converting the card data into the noise like signals i.e. spread spectrum signals.
[0014] Yet another object of the embodiments herein is to provide a method and a system for mutually authenticating a dongle device and a payment server.
