3. Should have access to the SMS's sent and received.

4. Generate SMS's based on actions required by the user, encrypt them using AES/stored key. General SMS message format should be "SMTF01,". Ciphertext should be as follows based on use-cases described.

=An ID to trace responses received later.

=Recipient selected from the contact.

=Amount (unformatted)

4.2 SMS for balance inquiry - "INQ00,"

5. Parse and respond to SMS's received in store. They follow the same syntax described in 4 and should be process if it has come only from Application Center number. Decrypt using AES/stored key.
