What We Set Out to Improve.

Industry
Hospitality

Global resort group requiring a unified mobile identity layer across different Property Management Systems (PMS).

How We Worked
Dedicated product team

IoT Architect + 2 Mobile Engineers + SRE Lead embedded within the Digital Transformation office.

Goal
Digital Guest Experience & Ops Efficiency

Bypassing front-desk slowdowns by moving room access and identity verification to the guest's device.

What We Built
BLE IoT Network

A practical solution designed around the client’s existing tools, teams, and day-to-day workflow.

What Was Getting in the Way.

The group’s older arrival process relied on manual passport scanning and physical keycard encoding, creating 45-minute slowdowns during peak resort rotations. This delay directly lowered guest satisfaction scores and increased front-of-house labor costs.

The biggest issues were arrival congestion, keycard overhead, and security blindspots. The team needed a faster, clearer way to manage the work while keeping the right checks in place.

Arrival Congestion
Peak seasonal waves caused lobby backlogs, damaging the luxury first-impression brand trust.
Keycard Overhead
Physical card loss and encoder maintenance costs exceeded $180k annually across the portfolio.
Security Blindspots
Older keys lacked live audit trails, making it difficult to verify room entry timing during liability disputes.
The Solution

What We Built.

01
Encrypted Identity Handshake
Added a secure asymmetric key exchange between the resort’s cloud backend and the mobile device via OAuth2-gated BLE sessions.

Before and After

How the Workflow Improved.

Area
Before
After
Access Media

RFID Keycards

Easily demagnetized, prone to loss, and requiring manual desk intervention.

Mobile BLE Key

Software-defined access delivered instantly to the guest’s own secure device.

Guest Identity

Manual Verification

Front-desk agents manually checking IDs against printed reservation logs.

Digital Onboarding

Automated biometrics and OCR-based passport verification integrated into the mobile flow.

Staff Logic

Reactive Servicing

Staff only notified of guest arrivals after the desk check-in was completed.

Predictive Arrival

Geo-fencing alerts notify housekeeping and concierge of guest arrival on property.

Key Features

How We Reduced Build Time.

Tested foundations helped the team spend less time on setup and more time on the parts that made this product useful.

What accelerated the work

4 reusable building blocks
01

IoT Handshake Module

A tested starting point for iot handshake module reduced repeated setup work.

02

PMS Connector Module

Reusable work for pms connector module let the team focus more time on the client’s specific needs.

03

Hardware Health Monitoring

This made it easier to add hardware health monitoring without rebuilding common foundations.

04

Resource Auto-Scaler

A tested starting point for resource auto-scaler reduced repeated setup work.
