Abstract
The present invention teaches a tamper-proof electronic bolt seal which contains a bolt assembly and a seal body. The gist of the present invention lies in the bolt assembly which contains a casing, and a circuit board elastically suspended inside the casing. When a burglar grinds a bolt head of the casing, an internal circuit of the electronic bolt seal is automatically disrupted so that the tampering of the electronic bolt seal can be detected.
