Hardly anyone has not heard of the eCheckin application!
A superb application that allows guests to log in in a simple and fast way eVisitor system. Forget about the tedious process of manual data entry guests and with just one scan register your guests on eVisitor directly from applications. Also, apart from the mobile app, you can also enjoy the desktop version inCheckin!.
eCheckin module costs 5,00 €/month, no matter the accommodation/hotel size, so it should be shown accordingly for every chosen number of units.
