READ AND WRITE MIFARE ULTRALIGHT C NFC TAG

PHASE 1 A windows C#.NET application that can read and write a Mifare Ultralight C NFC tag(sticker). This application should be able to: 1. Read existing information from the tag 2. Write specific information in the tag This script should be reusable in other C# applications Functions of the writing app: 1. Be able to write specific information on the ultralight c nfc tag 2. The information written on the tag should be encrypted using AES 256 algorithm 3. The data format of the details written should be plain. There should be no use of command or NDEF 4. Once data is successfully written on the tag, we need to be able to view information written on the tag in an information log. Once in a while our developers might ask you to display the information in a windows form textfield or a message box. 5. Data should be written from the fourth page of the tag. The length of the data is 96 Bytes. 6. Once the above is successful, we shall “write protect” the tag Note that you shall receive necessary guidance from our development team. Functions of the reading app: 1. The reading application will work with the ACR 122U NFC reader 2. It should be able to decrypt information in the tag and read it PHASE 2: This phase requires android applications that will read and write information on the same tags. Ultimately, when a tag is written on by the C# application, the same tag should be decrypted and read even by the android application. In this phase we shall have similar functionalities as phase 1 but the code should be written in native android. Note: 1. Tags written and encrypted on by the C# application should be decrypted and read by the Android application 2. Tags written and encrypted on by the Android application should decrypted and read by the C# application 3. The preferred encryption algorithm for all phases is AES 256 I have attached supportive resources for source codes which our developers had started working on
