Self-service is a system that allows customers to access and manage services on their own, without needing assistance from staff. This can be seen in places like grocery stores where self-checkout machines let shoppers scan and pay for their items independently. It empowers users to take control of their experience, making transactions quicker and often more convenient. In the digital world, self-service is common in online banking and customer support. Users can log into their accounts to check balances, transfer money, or find answers to their questions through FAQs and chatbots. This approach saves time and enhances user satisfaction by providing immediate access to services.
