During testing the developers of PMS Shelter confirmed the presence of a working interface with HSU electronic hotel locks. Testing was conducted with the team of LLC "SPECTR", which is the owner of the Shelter software.
Since our interface is based on the TCP/IP protocol this test was conducted remotely. The peculiarity of the protocol implementing based on the Internet technology allows to build geographically distributed solutions, when, for example, the server with PMS is located in the main building of the hotel chain, and the proximity encoders are connected to clients in other buildings anywhere in the world.
