Loss detection in real time for self-checkout at point of sale for grocery or convenience stores. Using EdgeX Foundry to combine POS, RFID, Weight Scale and Computer Vision data all in a single pane of glass and use it to alert associates in real time. This demo showcases how to take advantage of data from sensors currently available in stores to create a better solution compared to using a single sensor (i.e. weight scale).

Intel announced the Open Retail Initiative (ORI) last year at the National Retail Federation tradeshow. ORI is a collaborative effort led by LF Edge member Intel and top technology companies who believe that open, accessible solutions will accelerate iteration, flexibility, and innovation at scale. To empower digital transformation in retail, ORI promotes EdgeX Foundry as a common, open framework to allow retailers to access data across applications, removing silos and unlocking insights that improve services and experiences.

For the one-year anniversary of ORI, six initiative members Edgify, Flooid, Shekel and LF Edge members HP, IOTech and Intel inspired by the initiative, worked together on a demo for the Intel booth that showcased the value of Real Time Sensor Fusion for a loss prevention use case at self-checkout. The retail environment has become incredibly complex. The latest technologies enable data-driven experiences and unlock business value like never before, yet there is still a lack of interoperability making it difficult for retailers to deploy integrated solutions with speed and ease. The demo illustrates how integration roadblocks can be a thing of the past.
The demo pulls together real time data through the EdgeX middleware from different common systems including POS real-time transaction log, CV-based object detection, scale solution, and RFID, and data fusion—all in a single pane of glass.
NRF 2020: Intelligent Loss Prevention – A collaboration of six partners, inspired by the spirit of Intel’s Open Retail Initiative (ORI), the demo showcased Real Time Sensor Fusion (RTSF) using EdgeX open source middleware to combine POS, RFID, Scale and Computer Vision data —all in a single pane of glass.
Much of the data created in physical retail today, i.e. at brick and mortar, is not used or a portion of it is aggregated to be used later. Data is usually trapped in silos and make it difficult for retailers and technology integrators to merge and use data, especially in real time. Innovation is hampered because of:
Intelligent Loss prevention is just the beginning, Intel and its partners used this demo to demonstrate what’s possible when a community works together and uses open standards to solve today’s real retail problems: LF Edge’s EdgeX Foundry architecture allows access to data across applications in real time allowing retailers and technology vendors to unlock insights that improve services and experiences. All this is possible by augmenting common existing assets, rather than rip and replace.
Retailers increasing self-checkout for customer convenience continue to face challenges to detect and prevent theft. No single sensor, i.e. RFID or scale, is theft proof at self- checkout. That said, combining different sensors, each with unique detection attributes can improve object detection and reconciliation accuracy. The tradeoff though, in traditional architecture, is a complex integration effort among sensors and the Point of Sale solution. Using a modern architecture, a community approach and open standards integration complexity becomes a thing of the past.
The POC combined data from RFID, Scale, and CV POS RTTL to determine if an item had been scanned or not. RFID was Intel based open solutions RSP. The discrepancy was displayed differently showcasing how the data could be reutilized based on the end users preferences without a large effort.

Back to the caveat of having to integrate with a point of sale solution for the loss prevention use case and the challenges mentioned earlier from to lack of interoperability and data silos and how to tackle them. After the POC described above, Intel, fellow ORI members and the EdgeX community collaborated to create an NRF demo using enterprise ready applications.
According to flooid (formerly PCMS) a traditional integration with a POS solution can take 6 months vs. the weeks the demo team had to work on this demo which was only possible by:
The entire demo took 3 months. The speed of integration took 2 hours to 2 weeks for each vendor. Flooid was able to integrate with EdgeX in a couple of hours. It took a couple of weeks for all the other applications to integrate to EdgeX and a 5-day onsite meetup to bring all together. The remaining 2 months were dedicated to hardening the solution and for each vendor to work on nuances for the physical sensor and to tune their specific applicational requirements. Finally, each application provider focused on their area of expertise, i.e. POS did not have to be a CV or RFID expert and vice versa. As a result a System Integrator and or the POS provider can focus on new use cases to build business value while reducing the integration effort and risk.
