There are mostly two ways for a guest to check-in. The first one is when the host meets them in person and hands them the key, which is called meet and greet. The second one is contactless or self check-in. In a self-check-in method, the guests can get the key and access the serviced accommodation using a smartlock, keypad, getting the key from one of the building’s staff, etc. Even though some of the hosts prefer to welcome their guests in person, if you manage multiple properties, it is almost impossible to meet and greet all of them. Moreover, the recent pandemic caused contactless check-ins to grow in popularity among both guests and hosts.
