Who are the major equipment manufacturers for hotel guest room access systems? I've only done a little bit of research so far but this seems to be a whole different world from commercial access control. What I've found so far is:
Kaba - ILCO and Saflok
Onity (a UTC company)
VingCard (owned by Assa Abloy)
SALTO
Are there any others?
Also, in a typical hotel, do they use the hospitality/guest room keycard system for all areas, or do they typically use the hospitality keycard system just for guest room and guest amenities while having a separate EAC system for administrative space, offices, Elec/Mech/IT rooms, etc.?
