When it comes to holding a business event you have a mountain of options to choose from. For some it is all about showing off the latest product or gathering together like minded suppliers to offer the latest stock to buyers or maybe it is about sharing information. There are a number of ways in which you might like to use a Visitor Management System such as the ones from https://www.ofec.co.uk/web-and-software-development-services/digital-visitors-and-staff-signing-in-book.aspx to be able to book people into your event. The way in which you use this will depend on the type of event you hold.
If you are showcasing your latest products you may want to use a sign in system to allow people to access certain areas of the show. This could be a zone that is for stockists only or for those people who have pre-registered that you can enter into the system.
This is a great way to impart knowledge and industry updates to a large number of people in one go. If you are holding a conference in your own office space you could use the sign in system so people can register that they have arrived at your conference which will help to not overwhelm your recpetionists.
