When a price change or update occurs in the store's database, the central system sends the new information to the BLE tags via Bluetooth. These tags receive the data and update the displayed price accordingly. This real-time updating capability is incredibly efficient, allowing for swift changes without the need for manual adjustments or printing new labels.
The use of e-ink displays is crucial for these tags. E-ink displays offer a low-power solution that only consumes energy when updating the displayed content, leading to prolonged battery life. The energy efficiency of BLE tags is a standout feature. They often operate on coin-cell batteries that can last for months or even years before needing replacement.
Overall, BLE electronic price tags revolutionize the retail industry by streamlining price management, reducing human error, and offering a dynamic, efficient, and cost-effective solution for keeping product information up-to-date in stores.
