Which of the following technology can be used inside a store to track which aisle a customer is in?

The use of RFID (Radio Frequency Identification) tags on shopping carts is an effective way to track customers within a store, including identifying the specific aisle in which they are located. RFID technology works by embedding small tags that contain a microchip and antenna, which can communicate with RFID readers placed throughout the store. When a shopping cart equipped with an RFID tag passes by a reader, it sends information about its location, allowing the system to determine which aisle the customer is in.

This technology provides real-time data enabling stores to understand customer behavior and flow, adjust inventory management, and enhance overall shopping experiences. RFID is particularly advantageous because it doesn't require line-of-sight scanning, which is a limitation of other technologies, such as barcodes or QR codes. This means that movement can be tracked seamlessly as customers move through different areas of the store.

In contrast, while barcodes and QR codes require manual scanning and thus would not efficiently track customers' movements in real-time, geolocation data from cell phones can provide location information. However, its accuracy typically depends on GPS availability and signal strength, which can be less reliable indoors due to interference from walls and other structures. Therefore, RFID technology on shopping carts represents the most effective method for tracking customers' locations within a
