<p>@futuremind has said it all. Technology may not be able to stop cheating. Technology has brought cloning apps and tracking devices but still people cheat.</p><p>In my country people use the diabolic way to tell if someone is cheating and most times the end result is always very brutal.</p><p>Truth is why do you want to catch your partner cheating red handed. Every cheating partner has an usual behaviour they display that makes their partner suspect something is not right. Usually when you have the gut feeling that your partner is cheating, chances are he or she is actually cheating. If technology reveals it to you then what next? You try to make it right or you walk away.</p><p>I feel it is a lot much work having to monitor someone all day through a device to know if they are cheating or not. Is it even worth it?</p>
