byte to chart

hy have question
i use rfid id12
i use method turn badge chart looks tricky.
it not clean me arrays dirty me in second pass.
is there better solution?

code: [select]


void onreadtag(byte *tagvalue)
{


    serial.print("got tag: ");
    printtag(tagvalue);
    serial.println("");




          string codest0;
           string codest1;
            string codest2;
             string codest3;
              string codest4;



          codest0= string(tagvalue[0], hex);
          codest1= string(tagvalue[1], hex);
          codest2= string(tagvalue[2], hex);
          codest3= string(tagvalue[3], hex);
          codest4= string(tagvalue[4], hex);



       //   string datastring1;
         string datastring1;
         datastring1  = '#';
         datastring1 += string (codest0);
         datastring1 += string (codest1);
         datastring1 += string (codest2);
         datastring1 += string (codest3);
         datastring1 += string (codest4);


         char message_buff2 [13];
         datastring1.tochararray(message_buff2,13);


          serial.println (message_buff2);

all want print in hexidecimal? use serial.print(val, hex).

if want make string hex representation in there methods. why want that?
