 It's not end yet, block #0 is *NOT* meant for data storage, so all in all, instead of 1k (64 blocks * 16 bytes) we get 47 blocks (752 bytes).  
 During development I decided to take away one more block for sketch metadata (number of parts, code size etc) so we end up with 736 bytes of storage available per 1k tag (also it makes code a bit smaller, yay!).  
 
-Full 28672 byte code (in the worst case) will take up to 40 tags. Don't forget, that they will have to be scanned in specific order or your uC will crash at some point.

 I don't know why, but millis() is not working ¯\_(ツ)_/¯
 
 Also, I didn't have any experience in working with AVR bootloaders nor RFID tags.
