…dd improved error handling a cleanup method using atexit The readCard method will only return an UUID if it's got the correct length and wasn't returned last time to prevent stuttering caused by spamming unnecessary or wrong data. Add improved error handling for SerialExceptions and close the used ports using the Serial.closed() method registered with atexit. Remove unused RPi.GPIO module from code.
