Hi,
i would like to know if it is possible for a micro-controller to save additional data without reprogramming it.
for example, i have an RF Reader, and if i press a button on a micro-controller, the ID of a RF Tag will store on the micro-controller.
another example is, if i would like to alter the predefined data on the code without reprogramming/rebuilding it so that i can have additional tag6[13] and the maxtag will become 6 and this data's will remain even if the micro-controller is powered off and switched on again.
I am asking if it would be possible.
thank you for any response.

Code:
//Register your RFID tags here
char tag1[13] = "1E009A4067A3";
char tag2[13] = "010230F28243";
char tag3[13] = "01023C013A04";
char tag4[13] = "01023101093A";
char tag5[13] = "01023C0A4376";
int maxtag=5;
