A MiFare Classic library for Windows Phone 8.1, Windows Store 8.1 and Desktop apps

You must have a Lumia 830 or newer device. Older devices do not have the chipset support for the low-level APDU access this library needs. This will not work on a Lumia 930 or any previous hardware, even after updating to 8.1.

This library contains a detection routine to determine if a device's NFC reader has a supported chipset.

You must enable the Proximity Capability and NFC Requirement.

This will work in a Windows Store 8.1 app that is meant for enterprise distribution. It will not pass Store validation as it uses unsupported Win32 API calls (WinSCard.dll).

You must enable the Shared User Certificates capability to use this library. [I'm not totally sure why this particular capability controls access to WinSCard, but without it you get UnauthorizedAccess exceptions coming from the AppContainer.]

No special requirements.

On the desktop, this library has been tested with the HID OMNIKEY 5x21 series readers and the HID OMNIKEY 5427 CK in CCID mode. It should work with other PC/SC compatible readers but if you find an issue please open up a bug.

There are two sets of sample projects in this repo:

This is in the samples\MiFareReader.* project directories. This project shows basic usage and will loop through the 16 sectors of a classic card to read whatever data the default keys will allow.

A more advanced sample in the samples\Scenarios.* directories. This project shows atwo potential scenarios:

1. A user provides a PIN used to protect some data on the card. An app can then authenticate a user against the card to read the stored data. This could be a generated secret known by a server as a surrogate/strong password.
2. A ski lift ticket system where a cashier encodes the expiration date of the pass onto the card and a lift agent/gate validates the expiration date.

This library is made possible by

• NFC Smart Card Reader PC/SC Library
• A .NET MiFare Helper Class
• NXP and HID's documentation
• PC/SC Working Group specs
