I have been using this from many years now! It has helped me keep my workplace safe during Covid time as it makes sure that only essential people enter our premises without any worry. Also i really like how easy they make everything very simple which gives more confidence in users because if something goes wrong or there's an error we can easily contact support team via chat option provided by them. Nothing so far but would be great to recommend others try out too since its free service available to everyone. Its such a useful tool not just at home but anywhere else including offices etc! We use this product at office where most employees tend to come daily (even though some days might go off) - hence keeping myself protected while working.
