High-touch refers to the involvement of personal attention and service. In business, the term often refers to situations where trust between the customer and employed individual(s) is necessary. High-touch areas include: medicine, wealth management, real estate, and legal. Stock trading done by humans, as opposed to automated trading or using online brokers, is also referred to as high-touch.
High-touch may also refer to the frequency in which a surface is touched.
High-touch was coined as a term in response to "high tech." High-tech, as opposed to high-touch, is when customers don't need human interaction to perform activities such as onboarding, ordering, and account management. High-tech services, such at chatbots, allow customers to get what they want on-demand.
