Billing Option #4 – Hotel PMS Billing Plans Create billing plans that work in a similar fashion to pre-paid telephone cards. With this functionality, the Internal Web Server (IWS) of the NSE allows the definition of billing plans for time ‘x’ over period ‘y’. Standard billing plans (time x = period y) can be used concurrently. For example, multiple plans with flexible billing event options can be enabled such as: Plan A: 24 hours, 256kbit/s downstream, 128kbit/s upstream, public IP address, $15 Plan B: 8 hours to be used over 5 days, 512kbit/s downstream, 256kbit/s upstream, private IP address, $35 Plan C: 1 week, 1mbit/s downstream, 1mbit/s upstream, public IP address, $99 In addition to credit card billing, Property Management Systems used by hotels are also supported along with the internal data base of the NSE and billing via Nomadix’ secure XML API.

Billing Option #4 – Hotel PMS Micros Fidelio Nomadix has extended its existing interfaces to the popular Micros Fidelio PMS system to include three new interfaces. These interfaces have been tested and approved by Micros Fidelio (part numbers are available). TCP/IP interface for PMS post messages to Micros Fidelio Opera Serial FIAS-compliant post interface Serial FIAS-compliant extension to the existing Micros POS (i.e. 2-Way) emulation. The new interface includes the option to define a third query field (i.e. reservation number) to enhance security in wireless high-speed Internet access networks in hotels.

Billing Option #4 – Hotel PMS Post-paid PMS Nomadix first implemented post-paid PMS billing logic to support the proprietary NH PMS interface. Now, this billing logic has been extended to support all existing PMS interfaces (e.g. all five HOBIC versions, Marriott, Micros Fidelio, etc.). With the new functionality, the hotel guest now has the option to terminate his connection (via the ICC) and be only billed for the actual time he/she was online. Nomadix therefore offers the widest support for guest room billing methods including both pre-paid (i.e. pay-TV type charges) and post-paid (i.e. telephone type charges) methods.
