The invention discloses a seal used for controlled recording. The seal comprises a transfer printing body and a substrate and is characterized in that the transfer printing body is connected to the lower portion of the substrate, a circuit assembly containing cavity is formed in the upper portion of the substrate, at least one lower hole is formed in the transfer printing body in a penetrating manner, the substrate is provided with upper holes corresponding to the lower holes, and a switch probing out of the transfer printing face from the upper holes is arranged in the containing cavity. Themonitoring switch for probing out of the transfer printing face is arranged, during use, every time the transfer printing face falls on paper, the monitoring switch can act to output monitored signals, the monitoring area is transfer printing face covering, and the seal can carry out detection every time.
