In order to provide a seal mechanism for non-standard containers or other transport containers that do not have a bolt, the customs will be the first in the world to seal the container with electronic paper seals. This seal uses the paper seal to combine RFID, and its communication band adopts NFC (Near Field Communication) specification, which can be used to seal and read with the smart phone. It is helpful for the deployment and promotion.

Electronic paper seal adopts the design of double-layer. The inner layer of the seal contains identification chip which is provided with encryption mechanism and not easy to forge and copy. The circuit structure and antenna will be destroyed when the seal was torn. This situation can be detected easily by portable device. The outer layer is covered with waterproof film that can adapt to bad climate. It also can be identified easily by the naked eye if the seal was torn.
