Hi Corion, thanks again. this time again I have update the code to more detail. Is this helpfulnow ? Look at the regular expression at line 5. This expression needs to be matched and the entity of UPDATE section is added in this post, this is how it is working, the scanner is connected to com port if com port matches a receiver thread starts at command prompt. 

use strict;
use warnings;


use constant UPDATE; 
use constant TIMEOUTVALUE => 10;
while(1)
    {
     if ($scan = PERSONID) {
        #give status for the book, for example - borrowed 
     
        }
     elsif ($scan = Book)
        {
         if ($transaction->{'STATE'} = PERSONID)
            {
             push (@(transaction->{'BOOK'}))
            }
         
         my $valid = 1;
         if (($transaction-> TIMEOUTVALUE) >= time() && ($transacion->
+{'STATE'} = PERSONID))
         if ($valid) { $transaction->{'STATE'} = UPDATE; }
        }
     if (($transaction->{TIMEOUTVALUE} >= time()) && ($transaction->{'
+STATE'} = BOOK))
        {
        
        }
     else {$transaction->{'STATE'} = UPDATE;
     
     
          }
    } 
    if ($transaction -> {'STATE'} = UPDATE) {
        my $book = join("&iid[]=", @{$transaction -> {'BOOK'}}) # if t
+his is true then it updates
          }
