After adding the library and restarting the Arduino IDE, I loaded the example card read sketch and it worked perfectly. the Serial number for each tag I had showed up in the serial monitor exactly as I expected.
+ Worked perfectly on first attempt
- No documentation
Now that I have found a working library I would purchase another if I needed one.
Docs were thin and I had to cobble together the information from Adafruit and other sources to get it to work.
If I had to do it again I think I would pay the extra for the reader from Adafruit.
