Digital Shelf Labels Usher in New Era for Physical Retail: Dynamic and Personalized Pricing Concerns Emerge
Retailers across Australia and New Zealand are rapidly transitioning from traditional paper price labels to digital Electronic Shelf Labels (ESLs). This technological shift enables instantaneous price updates across all in-store products, bringing online-style "dynamic pricing" to physical retail locations. However, the potential for "personalised pricing" targeting individual customers has raised significant concerns.
ESL Adoption Surges Across Australia and New Zealand
Millions of ESLs have been installed over the past year, marking a major technological shift in the retail sector. Woolworths, for example, has deployed approximately 17 million ESL tags in over 600 Australian and 170 New Zealand stores, with comprehensive store conversion plans underway. Coles and Bunnings are currently conducting trials, while Dan Murphy's completed installation in all 273 branded stores in 2024.
Efficiency and Sustainability Benefits
Retailers advocate for ESLs due to their significant operational advantages. They state that ESLs dramatically improve efficiency in price updates, drastically reduce paper usage, and free up staff from manual price-changing tasks, allowing them to focus on more customer-centric activities.
The Rise of Dynamic and Personalized Pricing Concerns
Dynamic pricing, where businesses adjust prices in real-time based on factors like demand, is becoming increasingly feasible with ESL technology. While this can sometimes lead to consumer discounts, it also carries the potential for higher costs as prices fluctuate.
Predicting Individual Spending Limits
A more significant concern revolves around personalized pricing. This involves AI systems leveraging personal data—such as credit history, location, and buying habits—to predict the maximum amount an individual customer would be willing to pay for a particular product.
"Digital tags could facilitate different consumers paying different prices for the same product concurrently in-store, which he considers unfair."
Experts, including former ACCC chair Allan Fels, have voiced apprehension that these digital tags could enable different consumers to pay varying prices for the same product simultaneously within a store.
International Scrutiny and Technological Capabilities
Concerns over this technology are not confined to Australia. In the United States, unions and lawmakers have actively advocated for a ban on ESLs in large grocery stores. Their fears centre on "surveillance pricing," a concept that integrates tools like facial recognition, AI, big data, and digital price tags, potentially leading to increased consumer costs. An investigation notably revealed that the online grocery app Instacart had already charged some customers different prices based on their personal data.
The Tech Behind Personalized Pricing
The current generation of digital tags is highly advanced. They are cloud-connected and incorporate Bluetooth or NFC technology, enabling interaction with smartphones and providing the technical capability to display personalized prices directly to individual shoppers.
Australia's Future Retail Landscape
Australian retailers have not yet explicitly stated whether ESLs will lead to personalized in-store pricing strategies. Legally, businesses are permitted to use surge or personalized pricing, provided they do not mislead consumers or discriminate based on protected attributes. New price-gouging laws, effective July 2026, will introduce measures to prevent very large retailers from charging "excessive" prices relative to supply costs.
Legal Framework and Industry Predictions
Industry experts widely anticipate that digital price tags will make in-store surge pricing a common occurrence. They also predict a more sophisticated approach to personalization, including an increase in loyalty-member and personalized discounts designed to compete with online platforms.
"The ultimate impact on consumer perception and acceptance remains to be determined."
