RMS – Onity Interfaces
InfoDEN released its first Onity interface, for RMS, on the 3rd of December 2004. Since then, InfoDEN has expanded its range of RMS interfaces for the various Onity platforms and protocols. InfoDEN’s range of Onity interfaces now includes the following platforms:
RMS – Onity Integrated Key Interfaces
These interfaces use the integrated “Cut Keys” dialog in the box in the RMS Reservation Screens, to encode guest keys.
They allow multiple keys to be encoded for each RMS reservation.
They are suitable for multiple person occupancy environments, where several people may be linked to a single RMS reservation.
Such as Hotels, Motels, Apartments, etc.

RMS – Onity Automated Interfaces
These interfaces automatically generate a Mobile Key when reservations are checked-in. They are generally used in remote reception or contact-less check-in environments. These interfaces do not have screens and do not require staff intervention to generate a Key.
Currently, the automatic interface is only available through an additional Automatic Key add-on, in the OnPortal Mobile Key – Add-on.
HT24 / HT28 – RFID
The HT24 and HT28 RFID interfaces allow staff to encode Onity RFID keys for RMS Rooms, directly from the RMS Reservation screens. It is the most commonly used interface in the accommodation sector, where keys are encoded for rooms.

Onity Interface Protocol | Onity PMS Protocol |
Access Type | RFID Card/Fob |
Common Areas Support | Default and Optional via PMS Authorisations |
RMS Module Required | InfoDEN Door Locks through RMS Module Market |
Interface Type | Integrated into RMS Reservation Screens |
OnPortal – RFID
The OnPortal RFID interface allows staff to encode Onity RFID keys for RMS Rooms, directly from the RMS Reservation screens. It is the most commonly used interface in the accommodation sector, where keys are encoded for rooms.
The key feature difference between OnPortal and HT24/HT28 is that OnPortal also includes the DirectKey Mobile add-on option.

OnPortal – DirectKey Mobile Add-on
The OnPortal DirectKey Mobile interface for RMS is an add-on module to the RFID interface. It allows staff to encode Onity DirectKey mobile keys directly from the RMS Reservation screens. Staff can encode both RFID and BlueSky keys for the same reservation. Note: currently RMS only supports one mobile key per reservation.

OnPortal- DirectKey Mobile – Auto
This is an add-on to the DirectKey Mobile interface for RMS. It automatically generates an Onity DirectKey mobile key when a Reservation is checked in. This function works for both manual staff check-ins and RMS Guest Portal Guest Self Check-ins. It can be enabled or disabled for individual reservations. Staff can still encode additional RFID keys for the same reservation. Note: currently RMS only supports one mobile key per reservation.
