The tradition seal just has some words and numbers on the seal. It can be copied and doesn't have any secure structure. It is very easy to tamper and you can't find out that the tradition seal was tampered by thief.
The E-seal has the Unique TID code that can identify the UID code even if the E-seal's appearance are the same. The thief can copy many tradition seals, but they can't copy RFID E-seal.
