I need an android application for recording visitors to a booth at a trade show. It should have the following features:
-Work on Android 2.x
-Run in the background and start automatically when android starts
-Allow a magnetic card swipe reader to be connected to the USB port. This device is designed to connect to a computer as a human interface device (HID) and sends data to the computer like a USB keyboard would.
-Read the data being sent by each swipe on all 3 tracks
-Encrypt the data with some basic encryption and a preset key
-Send the encrypted data by SMS to a specified phone number, split into multiple messages if necessary. This should be done every time a card is swiped.
-There should be an icon in the Applications menu that allows you to access the program to change the following options:
A. The encryption key
B. The phone number that the SMS messages are sent to
