hello i am in my final year engg and i wish to do project on embedded systems. i need to develop an application 'smart atm using gsm' to interface arm processor lpc2138 with an lcd, 4*4 matrix keypad, gsm transreceiver and all the coding is to be done in c++ or assembly language. in this project user can withdraw money from atm without his atm card, he will get two options at atm machine 1:with atm card 2:without atm card if he chooses 1 option the procedure will be same but if he chooses 2 option he need to enter an unique id and password to access the account then the system will call to registered account holder and ask for the permission whether to allow the person to access the account or not. if the account holder denies he wont be able to withdraw money but if he allows then user can withdraw money. please help me out with interfacing diagrams and code. thanks . gaurav singh
