Hola, compré este protucto hace unos días y necesito un manual para el respectivo funcionamiento del dispositivo. ¿Me puedes ayudar por favor?

Personalmente no tengo el manual, pero al conectar a la PC no tuve ningún problema al reconocer mis tarjetas que indica en el detalle del producto. Lo que pude identificar es que las tablets y teléfonos móviles no son compatibles

Hello, i am looking for the api documentation for this product?

the rfid reader returns the card number in any text editor or application that receives data through the keyboard

My other rfid system reads a fob as 23419200 from multiple sources. this reader reads the same fob as 0015354624. why is that?

depending on your system you are using you may need to purchase a different reader. You can also set the system to read from a door then present the fob to that reader and see if you get the same results.

Will this unlock my computer

Yes if you use a 4100 rfid chip it will output it as plaintext, works on my PC
