Bactericide ATM's keyboard intelligent systems

Contamination from the ATM's keyboards and very much users of them cause the bacterial transfer to human. So, destroying these bacteria has an important role in human health. The aim of the present study was to introduce an intelligent system which can reduce bacterial contamination from the ATM's keyboards. In this experimental study, a prototype of an intelligent system was made based on the bactericide effect of the ultra violet (UV)-ray. Before assessing this intelligent system, a sampling of ATM keyboard performed and the number of Escherichia coli bacteria considered for control group. The ability of the system was examined in order to test whether it works based on the number of referrers, and automatic UV-radiation (cut-of DUf). In addition, after UV-radiation for 5-20sec from 10cm, to an Escherichia coli infected ATM keyboard; a seri of bacteriological experiments were performed. The examination of different functions showed that UV-radiation (cut-of DUf) is performing based on identified cases for it automatically. The bacteriological experiments revealed that the system reduced the percentage of the bacteria to less than 1%. Significant differences were found comparing the survived bacteria with the control group (P<0.05). One of the conventional methods for cleaning the contamination of the ATM's keyboards is using antibacterial materials, which is an expensive procedure. The presented prototype is an intelligent system which reduces bacterial contamination of the ATM's keyboards.
