Multiple Tags: 125Khz RFID module - UART (RFR101A1M)

#1

Hello,

I am attempting to use the RFR101A1M RFID reader to read multiple tags at the same time. However, when I enter two tags within the read range it stops reading all together.

Here is my code so far:

[code]int x=13;
int i=0;
int a[12];

void setup()
{
Serial.begin(9600);
}
void loop()
{
if(Serial.available())
{
while(Serial.available())
a[i]=Serial.read();
Serial.write(a[i]);
if(i<=x){
i++;
}
if(i>x){
i=0;
Serial.println();
}
}
}[/code]

Any suggestions on how to read multiple tags?

Thanks

This module can only read one RFID tag every time, don’t try to use it to read multiple card :slight_smile:

Okay, can you recommend a reader that will?

Okay , just we do not sell a moudle that is able to read multiple tags, but we will consider your thought.
We will also appreciate any other suggestion.
