From 72b70b6ec4fa7da86a3ac0aacee699b18d94fc3b Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Wed, 28 Aug 2013 00:39:48 +0200 Subject: NFC: Define secure element IO API and commands In order to send and receive ISO7816 APDUs to and from NFC embedded secure elements, we define a specific netlink command. On a typical SE use case, host applications will send very few APDUs (Less than 10) per transaction. This is why we decided to go for a simple netlink API. Defining another NFC socket protocol for such low traffic would have been overengineered.
