Reading errors

[jolyonjenkins]

Hi
Thanks for writing the library. I have an issue which may be nothing to do with your code, which is that when using the example code, there are fairly frequent read errors - i.e. the data given is not what is on the tag. Usually the next read is correct. I could of course write code to only give a result when there are two consecutive identical reads, but this would slow things down. Are there any fixes you can think of?
