RFID based Secured access system using 8051 microcontroller (AT89C51)

[Bency]

Hi,

 

In the project RFID based Secured access system using 8051 microcontroller (AT89C51) there is no EEPROM used. So, all the card identification is stored in the microcontroller only. If there is a power failure then all data is lost. Am I correct here?

 

Can anyone modify the same to store the data in the EEPROM?

 

Regards,

you are absolutely correct bency. the card details are stored in the controller itself.. if you want you can interface your microcontroller with serial EEPROM 24C02 as explained here.

Thanks for your reply Nikhil,

 

Can you help me in consolidating the entire code? I am looking for RFID access system with EEPROM and I am not good at writing code. Thanks in advance
