BACKGROUND
1. Technical Field
The embodiments herein generally relate to a field of electronic transaction and particularly relates to a field of secure electronic transaction. The embodiments herein more particularly relates to a system and method for a secure electronic transaction using a universal portable card reader device.
2. Description of the Related Art
Currently, there are hundreds of payment card readers in the market. All of them are at least as long as the credit card itself. There exist different types of card readers. One type is traditional card reader with single rails,which allow a card to be held against the base of the reader by the user and moved across the read head of the reader. Another type of card reader guides a card by 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 reader.
The conventional payment card readers for electronic payment are bulky. Further the merchant has to produce the printed receipts for the customer, which is very cumbersome for the merchant handling multiple customers. Also the merchant has to keep a record of all the printed receipts, to avoid a dispute in the transactions. It is advantageous for an individual to make a payment to another individual or merchant by swiping or inserting his payment card through a card reader. To read a payment card today, the device should have the minimal dimensions of the width of the card and the depth determined by the position of the chip contacts. So the conventional payment card readers have to be 55 mm wide and 45 mm deep to read the card.
Also, the conventional payment card readers are different for different type of payment cards. For Example: a NFC card reader is required for reading for NFC cards, smart card reader is required for reading smart cards and magnetic stripe card reader is used for reading magnetic stripe cards etc.
In view of the foregoing, there is a need for a universal portable card reader device for reading any type of cards thereby eliminating the need for a multiple card readers for reading different type of cards. There is also a need for a compact universal portable card reader device. Further, there is a need for a system and method for providing a secure electronic transaction in a cost effective manner.
The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
