\Any idea what I need to change?
You make it sound obviously simple but somehow I just can't figure out what to change to get it to look for anything beyond 88 04 08 7A.What code do I need to change/add to have it look beyond that?
Start with your dump code. Figure out how to reliably read ONLY the 6-byte UID, and place that in a string. Use the string manipulation functions as mentioned above, and carefully check how the data looks like.
If it's a stream of data with a fixed length (this I would expect) you should be able to simply say "bytes x to y is my UID".
After that you can simply compare that UID with your list of UIDs, and take action based on it. It's a 6-character string so you should be able to use the strcmp() function - it shouldn't matter that the characters are non-printable.
