Which of the following is an application of technology in wholesale/retail trade?

Point-of-sale (POS) terminals are a specific application of technology in wholesale and retail trade, primarily because they facilitate the transaction process at the point where a customer makes a purchase. These systems not only record sales but also manage inventory, track customer preferences, and generate sales reports, greatly enhancing the efficiency and effectiveness of retail operations.

In the context of wholesale and retail, POS terminals streamline operations, reduce errors in sales transactions, and provide valuable data analytics that can drive business decisions. They are integral to managing customer relationships and improving overall customer service, making them a critical technological tool in the retail industry.

In contrast, the other options listed do not directly pertain to the wholesale or retail trade. Online medical information systems apply to the healthcare industry, interactive assignments are typically used in educational contexts, and robotic surgery is a medical advancement unrelated to trade sectors. Therefore, the choice of POS terminals stands out as a relevant and essential technological application in the retail environment.
