Time attendance system with multistation and wireless communications

This paper describes a time attendance and access control system based in biometric technology and wireless communications, named Wireless Temp I/O. This system allows a multistation approach which records, in simultaneous, the time of entrance and exit of employees in each access to the work space. Besides the time record, the system allows to couple mechanical systems to control access that benefit the existence of multiple stations. Wireless Temp I/O has reliability in the identification, communication and record of the log.
