The module is good if you need RFID that works at 125kHz. The external antenna is a bonus if you want, for example, to have the module on one side of the wall and the antenna on the other side of the front door wall. Caution: The data you get when you read the transponder as in the tutorial is NOT the serial number of the transponder. To get the unique serial number of the transponder, you have to "recalculate" the data obtained first. Search engines can help you further on how to decode the data.
