Walmart is phasing out self-checkout systems in favor of traditional cash counters, a decision influenced by customer and employee feedback aimed at enhancing the checkout experience. This shift comes as major retailers like Costco are exploring alternatives, such as AI-driven 'scan and go' technology, to streamline operations. The self-checkout model, which gained popularity in the early 2000s, has faced criticism for technical glitches and increased theft. In contrast, Walmart has heavily invested in artificial intelligence to improve various aspects of its operations, including delivery speeds and customer engagement, helping to boost online sales. Despite economic pressures affecting lower-income consumers, Walmart's value proposition has attracted a growing number of wealthier shoppers, contributing to a 2.3% increase in store visits in late 2025. The retailer's stock has also seen positive adjustments from brokerages following its market value reaching $1 trillion in February 2026.
