Current problem

I can't find a way to make communication between the card and smartphone encrypted.

Preferred solution

There is a MiFare desFire card, it supports encrypted communication through authorisation.

Can you add to your plugin the possibility of read with authorisation and write with authorisation?

iOS and Android

I'm not sure if it's possible on iOS. Core NFC only offers two methods for MiFare tags:

1. sendMiFareCommand
2. sendMiFareISO7816Command

The first is already available via the plugin. You may simply have to send a special command to the tag. However, I have never tested this myself. Feel free to give it a try using the transceive(...) method of the plugin.

Android, on the other hand, offers the following two methods:

1. authenticateSectorWithKeyA
2. authenticateSectorWithKeyB

I guess these are the methods you are looking for. Both should be easy to implement.
