Thanks for putting this together and great talk at DC.
More of a question than an issue- Did you have any concerns at all with the reader (output) supplying +5 signal/logic voltage when the PI's typically don't like to see anything over +3.3 for input? I've always dropped the input down with a few resistors but maybe it's no longer a concern?
Thanks again
