Hi Brijesh,

As per the driver specification, UNO can only drain a maximum of 100mA. On the other hand, UNO & RFID reader together consumes about 130mA as a whole. From this you can understand that insufficient current is the reason why the module power goes off when connected together and powered via USB. For this particular application, using a power supply adapter(for powering) along with the USB(for comm.) will be a great choice.
