Retail Asset Tracking with RTLS: Complete Warehouse Management Systems Guide

Retail operations management and warehouse management systems concern all aspects of keeping a store functioning well. In this blog post, we present Penguin applications of real-time asset tracking systems (RTLS) in retail operations management.

Physical Space:

A content management system can be used to upload maps (e.g. warehouse management systems), define interactive zones and aisles on these maps, create routes, and enter information related to each zone/aisle. Per-aisle information may also be integrated with retail inventory management databases. This retail technology solution is expected to simplify the onboarding of employees who can search for and locate items digitally through asset management software. ROI is built on reduced training costs and lost search time with warehouse asset tracking optimization.

Staff Administration:

Real-time asset tracking can automate attendance taking (in/out of the store) and staff presence checking against assigned zones. At Penguin, we refer to this as zone-based warehouse tracking systems. Tracking staff for attendance and presence purposes requires a tag or can be done using employee phone with the ability to request on-phone fingerprinting as a second-factor authentication for store operations management.

Business rules can be leveraged to notify/alert supervisors of absent staff or those who are outside their designated zones through asset management software. The ROI for this retail technology solution is derived from higher compliance and better efficiency. In scenarios where privacy is a concern, management can review the analytics based on aggregate trends using warehouse management systems.

Equipment Administration:

Penguin retail asset tracking can track anything that is bulky, moves, and is of significant value. For example, forklift warehouse asset tracking and wayfinding (usually done on a tablet mounted on the forklift) with the ability to fence off floor areas during un/loading events from the content management system. These fenced off areas will be automatically reflected in the suggested routes given to the forklift driver when moving inside the warehouse tracking systems. The ROI here is built on the reduction of insurance-impacting forklift-related workplace injuries through real-time asset tracking.

Furthermore, tracked equipment and assets provide for data-validated utilization information such as operating hours of forklifts, zones requiring them the most, etc. providing an important decision-making tool for retail operations management.

Security:

A key application of warehouse tracking systems is the tracking of security staff inside premises to ensure rounds are done as required (right time/right location). Certain types of tags have duress call functionality which can be integrated with public announcement systems. This retail technology solution enables an inexpensive $20 tag with a push button to become a cost-effective dispatching solution for store operations management.

Visitor Administration:

Warehouses and front shops usually support vendor accessibility for re-stocking purposes within retail inventory management processes. Penguin real-time asset tracking can provide ability to assign tags to visitors at check-in points, track them throughout the facility using warehouse management systems, issue alerts if needed (e.g. outside permitted paths/zones), and check-out once the trip is completed. Penguin makes such data available live on a map and captures historical records for incident verification through asset management software.

In this blog, we presented a brief list of applications of Penguin retail asset tracking and warehouse management systems technology in retail operations management.

Are theme parks really fun?

I have never been a fan of theme parks and cannot think of anything worse than spending thirty minutes in a hot summer day waiting for the thrill of 67-second amusement park ride. Can you?

Last summer, I went to Dubai for a 5-day business trip. On my last day and under repeated concierge recommendations, I thought: come on, let’s give it a try. I succumbed to visiting one of the local theme parks and here it was déjà vu all over again with literally 100s of people ahead of me on many of the rides I wanted to try. With only eight hours left before my flight, I had this sense of urgency to ride what I could.

I thought to myself: won’t it be nice if I could figure out which rides had the least wait times or even better booked a time-slot during which I can show up and be shown to the VIP line? I wish if an insider accompanied me to show what the craze is all about. Thus far, I totally understand why others desperately leave the amusement park or don’t even visit.

Theme Park Queue Management: Day Dreaming Solutions

Given that even many of the theme park restaurants had long wait times too, I certainly cannot be the only one wishing for a comprehensive theme park queue management solution. The need for mobile theme park solutions has never been more apparent. Possibly through my mobile app I can use it to book the theme park ticket and then schedule (yes schedule) the rides ahead of time using advanced mobile theme park solutions.

When it is my turn, the mobile application notifies me and even encourages me to try similar attractions but with short wait times or suggests numerous nearby restaurants, shows or special events without losing my spot in the queue. These suggestions could even be curated to my preferences based on past visitor behavior or guest profile.

Indoor Positioning – Smart Building Technology

Occupants and visitors of smart buildings expect sufficient intelligence to support profile-aware interactive services at different locations. This expectation drives the need for sustainable indoor positioning systems and advanced smart building technology. Venue operators who fall behind in adopting indoor positioning technology are likely to fall short of supporting use cases perceived as an integral part of the smart building era. Modern indoor positioning systems have become essential infrastructure for competitive advantage.

Is Indoor Positioning Really Needed?
In many cases, the location requirement may be served well enough by occupancy sensors. However, there are many use cases where accurate indoor positioning is required to (1) better serve the occupants and visitors and (2) develop an in-depth understanding of the traffic and ultimately usage pattern of the building. These use cases drive the need for accurate and sustainable indoor positioning that is owned and potentially monetized by the venue operators themselves. Indoor wayfinding is an example use case applicable in mega venues (e.g. shopping centers) where people will get lost, lose their cars and struggle to find what they are actually looking for.

Is it just Indoor Wayfinding?
Albeit the most obvious, indoor wayfinding is not the only use case built on indoor positioning. Value-driven use cases will vary by venue type:
In hospitals, the return on investment (RoI) of indoor positioning is primarily composed of two use cases: (1) wayfinding to reduce lost appointments and (2) asset tracking to reduce asset loss and time wasted looking for assets.
In airports, the RoI is primarily motivated by the reduction of late passengers causing delayed flight and heavy airline penalties.
In shopping malls, indoor wayfinding and proximity-aware advertising are the key use cases.
For the education sector, driving efficiency thru automated attendance, asset tracking, and even occupant tracking for safety reasons are the most obvious use cases.
Once deployed, indoor positioning platform can further augment the performance of occupancy sensors touted today for many standard smart building use cases as well.

 

 

Is the Technology ready?
There are many challenges for delivering an indoor positioning solution including continuously changing environments such as those in open and configurable office spaces and specialized infrastructure that is usually outside the realm of IT department expertise (e.g. various sensors, magnetic field etc.). Moreover, we face a lack of standardized technology and varying KPIs which are driven by the use cases.

However, there are many vendors today providing mature solutions. PenguinIN is one such provider who decided to distinguish itself by providing a turn-key managed indoor positioning solution where location of things is offered as a service. In this model, IT departments will not have to worry about infrastructure setup and maintenance and will offer the technology to internal stakeholders via API and SDKs. Maintenance will include periodic site surveys with calibration performed by our local support teams. This ensures that an accurate and stable position continues to be available long after initial system deployment.

Why not let others do it?
It is very tempting for venue operators to allow the likes of Apple and Google to provide and own the indoor positioning solutions in their venues. They are provided at seemingly no cost and no doubt a ubiquitous solution from Apple or Google may have its benefits particularly for the end user.

However, the issues which linger include those of data ownership, solution monetization, security/ privacy and accuracy KPIs.
Client data is a key asset for venue operators particularly when their marketing department – amongst others – are trying to develop data-driven insights to help with the decision making process. These insights may be offered to venue tenants and others who are interested to sell products and/or services to visitors of this venue.
In addition, venues may be liable especially that they are providing either the infrastructure or the connectivity links to harvest user data. This is particularly true with many jurisdictions mandating privacy regulations. Providing sensitive areas such as airports and hospitals, and any other industry where security is business critical need to prioritize security and privacy. Finally, such solutions may require a complete Wi-Fi and/ or BLE (Bluetooth low energy) infrastructure revamp.

Venues must actively pursue their own enterprise-grade solutions instead of going with Google and Apple for indoor wayfinding. The analogy is too stark with cellular carriers who have built multi-billion-dollar networks in the past and are struggling today to generate revenue while Apple and Google are using these same networks to monetize in innovative ways. Brick-and-mortar venues will suffer a similar fate to cellular carriers if control is relinquished to the likes of Apple and Google.

In an upcoming post, we will discuss the key elements in selecting an indoor positioning solution and introduce some of the KPIs that venue operators should look for before selecting their solution.
