Abstract
Card-type anti-miss/anti-theft alarm device including a portable mainframe and an alarm sub-frame each having a central processing/controlling unit and a power supply unit. One of the portable mainframe and alarm sub-frame includes an intermittent oscillating transmission unit, while the other includes a signal receiving unit and a sonic/optical warning unit. The alarm sub-frame is designed as a thin card with a dimension smaller than or equal to that of an existent credit card, whereby the alarm sub-frame can be easily placed and hidden in an article carried by a user. In case the user misses the article or the article is stolen by a thief and spaced from the user by a certain distance, at least one of the portable mainframe and the alarm sub-frame can emit an alarm to indicate the user of the location of the missing article. Accordingly, the user can easily find the article and the thief is scared.
