Yes, the RFID E seals are tamper evident. RFID E Seals are designed like the conventional bolt seal with two separate parts (male and female) packed together. Special care must be taken that the male and female parts which are packed together are used with each other to complete the unique circuit post locking.The RFID E seal can be read by a RFID reader only after locking. As the E seal is a passive RFID sealing device designed for one-time use, the only way to unlock it is to cut the same with a metal or bolt cutter, which destroys the internal circuit and the RFID seal cannot be read once broken.
