Hospitality carries a technology burden guests never see and never forgive. Wi-Fi has become the most reviewed amenity in the building, property systems hold payment cards and personal data that make hotels a favorite target for attackers, and PCI DSS obligations follow every transaction across front desk, restaurant, spa, and gift shop. Properties juggle dozens of vendors across internet, phones, television, point of sale, keyless entry, and surveillance, while copper lines that elevators, fire panels, and pool phones depend on face carrier sunset.
