Apex waterproofing is one of the rapidly growing companies in home repair and maintenance industry in the U.S. The first reason is the amount of money difference: When you can get repair services for a less price rather than spending on procuring expensive devices you can get your mobile repaired. This is however a software limitation, and people have managed to patch AOSP source to get around it and successfully communicate with UICC. Additionally, since an SE can host multiple applications, it has the potential to replace the bunch of cards people use daily with a single device. This is the NFC mode with the greatest potential for real-life applications. This has the greatest potential to become part of stock Android, however, as of the current release (4.1.1), it is still not available. It is a remarkable, all in one technological device geared towards the general public and it is still hugely popular.

This is a lot of (useful?) information, but we still haven’t answered the main question of this entry: how can we access the embedded SE? Again the answer to that question depends on how many CPUs your phone has, if there is more than one then there should be no problem. Hum sab ko aise lagata hai ke mahangi chej hi acchi hote hai but its rong yaar, agar iski kimat India ke cell phone jayada hote na to sab log kharid late. If younger children are involved, they can pick up a phone to call, but would they know how to use a cell phone or give out an address? An alternative way to use the UICC as a SE is using the Single Wire Protocol (SWP) when the UICC is connected to a NFC controller that supports it. Pretty much any mobile device nowadays has an UICC (aka SIM card, although it is technically a SIM only when used on GSM networks) of some form or another. The device is fitted with 0.3-megapixel camera with 5x zoom and several camera features like self-timer, white balance along with video recording capabilities.

AKAI Trio device hosts an inbuilt sound recorder and video player with video recording capability. Since an SE installed in a mobile device has equivalent or superior capabilities to that of a smart card, it can theoretically be used for any application physical smart cards are currently used for. UICCs are actually smart cards that can host applications, and as such are one form of a SE. Smart cards have been around for a while and are now used in applications ranging from pre-paid phone calls and transit ticketing to credit cards and VPN credential storage. In virtual mode the SE is visible to external readers as if the phone were a contactless smartcard. The SEEK project does provide a patch that lets the emulator talk directly to a UICC in an external PC/SC reader, but that is only usable for experiments. These modes are naturally mutually exclusive, so we can communicate with the SE either via the contactless interface (e.g., from an external reader), or through the wired interface (e.g., from an Android app). The embedded SE is connected to the NFC controller through a SignalIn/SignalOut Connection (S2C, standardized as NFC-WI) and has three modes of operation: off, wired and virtual mode.

What can Android do in each of these modes? The good news is that accessing it in a standard and (somewhat) officially supported way is possible in current Android versions. Samuel Finley Breese Morse – This PDF document provides a biography on the man who invented and improved upon a telegraph system which helped pave the way for wireless communications today. The SEEK for Android project provides patches that do implement the needed commands, allowing for communicating with the UICC via their standard SmartCard API, which is a reference implementation of the SIMalliance Open Mobile API specification. When connected to an Android device with and SD card slot, running a SEEK-patched Android version, the SE can be accessed via the SmartCard API. However, since the UICC is only connected to the basedband processor, which is separate from the application processor that runs the main device OS, they cannot be accessed directly from Android. In order to support communication with the UICC secure element, support for this needs to be added to both to rild and to the underlying proprietary library, which is of course up to hardware vendors.
