Review on Sensor Reader Module 13 56MHz Arduino by Jacob Noriega

As a result of using this RFID reader I found that it was incredibly easy to add proximity detection to my project. The module is compact and easily fits onto the top of my Arduino board, so it doesn't take up much space in my project box... It reads RFID cards and bracelets quickly and accurately, and I've had no issues with connectivity. However, the module doesn't come with any detailed instructions, so users may need to do a bit of research to figure out how to get started..
