The Cargo Handling Cooperative Project (CHCP) has initiated a major project, testing and evaluating e-seal technologies for intermodal freight containers. CHCP is a partnership between the U.S. Maritime Administration and private industry. The project will be conducted through such initiatives as Operation Safe Commerce, the Transportation Security Administration's Port Security Grants Program, and security initiatives begun by U.S. Customs. Electronic seals have been put forward as a way to address the security challenges presented by intermodal freight containers. However, they have not yet been applied on a wide scale basis in commercial applications, and any new equipment requirement must be based on a thorough, objective examination of the technology.
