August Retail Tech: Walmart Pivots on Payments and Lululemon Loses AI Lead

Walmart’s decision to adopt tap-to-pay options by the end of 2026 marks the end of its proprietary payment experiment. Industry analysts view the move as a concession to consumer demand, effectively ending the retailer’s attempt to maintain a closed-loop system. Meanwhile, Lululemon is searching for a new technology leader following the departure of Chief AI and Technology Officer Ranju Das, who exited just weeks before the arrival of incoming Chief Heidi O’Neill.

Target is aggressively countering the talent drain by appointing Chandhu Nair as its first-ever Chief AI Officer. Nair, formerly of Lowe’s, is tasked with embedding AI into frontline store operations. Elsewhere, automation continues to scale: Tesco is expanding its trial of Simbe’s Tally robots, while Morrisons has tapped Everseen to deploy computer vision at 200 locations to streamline checkouts. These moves arrive as retailers grapple with the complexities of human-machine interaction, highlighted by a recent incident where a Sainsbury’s customer was wrongly accused of shoplifting due to a mismanaged facial recognition alert.
