this is the code i added in my while(1) in main pgm.check and tell

while(1)
{
for(z=0;z<7;z++)  //command to display "swipe"
{
display(id[z]);
}	
delay(20);    //20sec delay
if(byte==8)
{
get();
}
delay(10); //10 sec delay to display the name
byte=0;
for(z=0;z<7;z++)  //again displaying "swipe"
{
display(id[z]);
}
delay(20);
if(byte==8)
{
get();
}
} 
}

What is this code doing?

 for(z=0;z<7;z++)  //command to display "swipe"
{
display(id[z]);
}

what is id[z]? You code is wrong. Why you are not using the code I posted?

why are you using this code 2 times in the while loop? It is not necessary.

In your code the below code is repeated 2 times

for(z=0;z<7;z++) //command to display "swipe"
{
display(id[z]);
}	
delay(300);
if(byte==8)
{
get();
}
delay(100);

i declared like id[7]="swipe".for displaying i'm using like this

Can't you use

 lcd_string("swipe");

instead of your

 for(z=0;z<7;z++) //command to display "swipe"
{
display(id[z]);
}

use any of the 2 codes given below.

while(1)
{
	if(byte!=8) {
		for(z=0;z<7;z++)    		//command to display "swipe"
		{	
                        display(id[z]);
		}

		delay(20)	    		//20sec delay
	}	
	else if(byte==8)
	{
		//clear display here
                get();
		delay(10); 	    		//10 sec delay to display the name
		byte=0;
                //clear display here
	}
 
}

//or

while(1)
{
	if(byte!=8) {
		lcd_string("Swipe your Card");
		delay(20)	    		//20sec delay
	}
	else if(byte==8)
	{
		//clear display here
                get();
		delay(10); 	    		//10 sec delay to display the name
		byte=0;
                //clear display here
	}
 
}

ya...i can give in both the way..but then also its not working...it displaying "swipe" continuously since it is in while loop..nothing is displaying other than that.
