Rfid ID-20MFIA Help

Hello there.

I bought the standard id-20 writer not the 12, and I snapped a few pins due to the spacing so I ordered a new rfid chip model ID-20MFIA

This is a reader/writer , im trying to get the thing to read card with no luck the id20 I 1st bought worked fine

is there a special code for this model, I need it for my door strike I have been trying this code with no luck

this model has 14 pins . please help thanks.

#include <SoftwareSerial.h>
SoftwareSerial RFID(2, 3); // RX and TX

int i;

void setup()
{
RFID.begin(9600); // start serial to RFID reader
Serial.begin(9600); // start serial to PC
}

void loop()
{
if (RFID.available() > 0)
{
i = RFID.read();
Serial.print(i, DEC);
Serial.print(" ");
}
}

It’s possible that the bare chip requires firmware to be written to it first.
