Provided is a substrate with a built-in electronic component that can minimize an occurrence of a deformation such as warping or distortion of the substrate with a built-in electronic component, which is caused by a difference in rigidity between a region of low rigidity and a region of high rigidity that are formed in a core layer thereof. The portable terminal includes a first body, a second body positioned facing the first body, and a slide module provided between the first body and the second body to guide the first body in sliding movement in longitudinal and transverse directions relative to the second body. The network element relays the credential and credential handle to the disk element, which adds the credential to a corresponding disk element credential cache at a location indexed by the corresponding credential handle. The location register is operable to process different network type messages on the location register. It is life saving and will help in the development of next generation superior vaccines.
