System and method for conveying card data using matrix bar codes
User credit card data or smart chip data or Near Field Communication data is easily transferred from a card reader to a host device via a matrix bar code such as a Quick Response (QR) code. Data transfer is performed by converting the card data into matrix bar code and allowing the host device to take an image and process the image to obtain the card data. Card reader will convert magnetic signal/smart chip/NFC data into machine readable form and then convert it into matrix bar code to be consumed by a device that is capable of capturing the matrix bar code. The card reader has the ability to encrypt the data before converting it into a matrix bar code.
