APPARATUS FOR MONITORING REMOTE WORK

摘要

An apparatus for monitoring remote work, such as cleaning. A cleaning person (120) at a remote work site (112) reads a certificate (102, 104) from a remote device (100). He or she sends a central system (130) a message (126) containing the certificate (102, 104) and also indicating the cleaning person's identifier (122). The central system (130) decrypts time and location stamps from the certificate and sends a cleaning company (150) a report (140) indicating that the cleaning person whose identifier (122) is "8196" has paid a visit to the site (112) indicated by the location stamp at the points in time indicated by the time stamps. The cleaning company (150) may send a report (152) about this to a customer company (110).
