I need help to make my tags names!!!

Sensors NFC & RFID

Hi guys, I am working on m6e - nano, sparkfun’s rfid product.

I just wonder how can I make each tags name.

I mean, when I attach a tag, I want to see this tag has a name. I attached an youtube link.

like this!!!

I try it but failed.

When I used mfrc rfid hardware, I found specific UID number and write like this.

if(mfrc.uid.uidByte[0] == 57 && mfrc.uid.uidByte[1] == 212

&& mfrc.uid.uidByte[2] == 173 && mfrc.uid.uidByte[3] == 109)

So when I attached specific tag, arduino interacted. But I cannot handle this nano product.

How can I using UID number to use?

please help… I have to graduate my school…

I used example 1 continuous reading. Add in loop () after printing the EPC bytes, the following: ```
MatchEPC(tagEPCBytes);


and add the following code in the sketch :

#define EPC_LENGTH 4 // use the last 4 digits
#define MAX_LIST 11 // maximum number of names / epc + 1

typedef struct
{
uint8_t epc[EPC_LENGTH];
String name;
} match;

// enter the last 4 digits of the EPC and the name
// as per examples

match matchlist[MAX_LIST] = {
{{0x15,0x40,0x80,0x29}, “Paul”},
{{0x10,0x41,0x67,0x09}, “soo031919”},
{{0x0,0x0,0x0,0x0},“end”} //THIS MUST ALWAYS BE THE LAST ENTRY
};

void MatchEPC(byte EPCBytes)
{
byte i, x = 0, MatchCount;

while (x < MAX_LIST)
{
// end of matchlist?
if (matchlist.name.equals(“end”)) break;

MatchCount = 0;

// look for match   
for (i = 0; i < EPC_LENGTH ; i++) {
  if(matchlist[x].epc[i] == nano.msg[31 + i + EPCBytes -EPC_LENGTH])
    MatchCount++;
  else
    break;
}

// complete match ?
if (MatchCount == EPC_LENGTH){
  Serial.print("found : ");
  Serial.println(matchlist[x].name);
  return;
}

// next entry in matchlist
x++;

}

// ooho…
Serial.print(“Could not find EPC ending on: “);
for (i = 0; i < EPC_LENGTH ; i++) {
if (nano.msg[31 + i + EPCBytes -EPC_LENGTH] < 0x10) Serial.print(F(“0”)); //Pretty print
Serial.print(nano.msg[31 + i + EPCBytes -EPC_LENGTH],HEX);
Serial.print(” “);
}
Serial.println(”\nMake sure to add in matchlist.”);
}

you are an angel!!! I solved it!!! I can graduate now!! I hope you work less and get a lot of money!!!
