working perfect But how do I add more tags to match, any advice, please?

Thank´s in advance.

The single tag to check in this example is defined as an array of 4 bytes - UID[4]. If you wanted to check multiple tags, then use a multidimensional array - e.g. UIDS[8][4] for 8 separate tags. Once you have read the tag, you would need to loop through the comparison multiple times for each tag (and each comparison involves a loop of 4 for each byte in the tag).

Thank you Steve, I will try to see if I am able to do it.
