Near Field Communication Based Digital Transaction Card

Abstract

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.
