hi
i am an student , i doing main project on RFID based payment system using GSM network ,
The payment system is completed in three steps namely:
1. Identification
2. Authentication
3. Database access and updates
ThePayment terminal has an LCD to show the current date and time and prompt you to enter your desired payment amount. When we enter amount, then LCD displays to please wave tag. When we wave RFID tag near RFID car reader, RFID tags are activated and the information on the tag is captured by the reader which sends it to the microcontroller for decryption. The microcontroller under use is AT89C51. Next, the user is prompted to enter the security code. To make the system quick and convenient, a 4-digit security pin is used for Authentication. In the third step, data is transferred between the user and the database which is conceived via air using GSM module for communication. mySQL is used here for server database management. In the database user information for particular RFID card & a 4-digit security pin is used for Authentication are verified & again details are send back & displayed on LCD. If given input matches with database information then on LCD payment is success will be displayed otherwise it asks again to enter the details.
I need to know how to interface RFID module, lcd 16×2, keypad 4×4, GSM module ( sim 300 ) all this at a time to AT89C51 ( 8051 ic) .
***********how data from microcontroller using gsm module data goes to database, using which commands, how to create databasefor my project , how a data gets upadets & information gets back to microcontoller & displayed on lcd as sucess payment.
please help me……………………………………………………..
hi im doing the same project and have the circuit for the atmega 16 interfacing but require interfacing details for 8051 too.
can u send that at16 ckt details about that to me my mail, [email protected]
