Near Field Communication Based Digital Transaction Card
Our paper aim is to design a reprogrammable smart payment card that replaces all other cards in the wallet assembled using an ultra low power e paper display, Bluetooth Communication, capacitive touch sensor and NFC. The controllers used in this project based on ARM Cortex M architecture. The main advantage of this paper is the card will be in constant communication with the smartphone. In case if the connection was lost, after a certain time interval the card interprets it as lost or stolen and will automatically disable itself. The user can re enable the card only by entering the authentication password on the card and from the smartphone app.
