EMV Smartcard Protocol Library

Project description

Build Status

A Pythonic implementation of the EMV smartcard protocol, which is used worldwide for chip-and-PIN payments. This is intended to be readable, tested, and heavily cross-referenced with the appropriate sections of the EMV Specification.

This also includes an implementation of the EMV CAP (aka Pinsentry) standard which is known to work for Barclays cards.

Installation

You’ll need the pcsc smartcard libraries on your system in order to build the smartcard bindings. On Ubuntu:

sudo apt-get install build-essential swig libpcsclite-dev python-pip

Then you can install emv from pip:

sudo pip install emv

To check if everything’s working, plug in a smartcard reader, put a bank card in, and run:

emvtool info

If all goes well, you should see some data about your card.

Command Line

This library ships with emvtool - a simple command-line tool for testing and CAP password generation. To fetch some card metadata, run:

emvtool info

To generate an EMV CAP one-time passcode:

emvtool -p <PIN> cap

You can also conduct CAP signing and challenge-response:

emvtool -p <PIN> cap -c <challenge>
emvtool -p <PIN> cap -c <accountno> -a <amount>
