2.4GHz: Requires connection via a dedicated USB receiver to the device's USB port. Generally compatible with most computers but supports only one-to-one connections.
433MHz: Relies on a USB receiver for pairing. Compatible with computers and industrial control systems, better suited for single-device long-range deployment.
Speed and Latency
Bluetooth: Moderate transmission speed with potentially noticeable latency. Suitable for low-to-medium frequency scanning tasks (e.g., retail checkout and mobile stocktaking).
2.4GHz: Offers high transmission speeds with low latency, highly suitable for high-frequency scanning scenarios (e.g., production lines and parcel sorting centres).
433MHz: Features moderate transmission speeds with minimal latency, meeting requirements for long-range and low-data-volume transfers (e.g., agricultural traceability and large-scale warehouse inventory).
Interference Resistance
Bluetooth: Operates within the congested 2.4GHz band, susceptible to interference from Wi-Fi, other 2.4GHz devices, and wireless signals.
2.4GHz: Benefits from dedicated communication protocols, offering superior interference resistance to Bluetooth and maintaining stability even in crowded 2.4GHz environments.
433MHz: With minimal competition, interference from Wi-Fi or other wireless technologies is highly unlikely, making it more reliable in complex industrial settings.
Applicable Scenario Analysis: How to Match the Best Technical Solution for Customers
Bluetooth Technology: Mobile Flexibility & Multi-Device Connectivity
The main advantage of Bluetooth scanners is their strong compatibility, which allows them to be directly paired with devices such as smartphones, tablets, and POS machines without the need for an additional receiver. Typical scenarios include:
Retail cashiering: Store staff use handheld Bluetooth scanners to scan merchandise and synchronize the data to the cashiering system in real time to improve checkout efficiency.
Mobile inventory: Warehouse staff can use Bluetooth scanners to connect to cell phone apps to conduct inventory flexibly between shelves and improve work efficiency.
Medical industry: In the medical environment, after scanning the drug labels, the data is transmitted to the hospital management system via Bluetooth, avoiding the hygiene hazards that may be associated with wired connections.
2. 2.4G technology: suitable for small and medium-sized fixed scenes
2.4G technology needs to be connected to the host through a dedicated receiver. Although its compatibility is not as good as Bluetooth, its anti-jamming ability is more stable and suitable for the following scenarios:
Production Workshop: When the assembly line workers scan the material labels, the data can be transmitted quickly to the workshop management system to ensure that the equipment works stably within 50 meters.
Courier station: After scanning the courier order, the data can be quickly synchronized to the computer, avoiding the loss of efficiency due to the delay of Bluetooth.
3. 433MHz Technology: Suitable for long-distance and high-penetration scenarios
433MHz technology, with its long-distance transmission and strong penetration ability, has become the ideal choice for large-scale outdoor or complex environments:
Large-scale warehousing: Warehouse administrators can scan the shelf labels from hundreds of meters away, and the data is transmitted in real time to the central server to ensure timely updating of information.
Logistics parks: truck drivers scan container barcodes in the parking lot, the signal can penetrate the iron skin of the carriages to ensure the stability of data transmission.
Agricultural traceability: Scanning the labels of agricultural products in the field, the data can be transmitted to the distant management terminal, which is convenient for tracking and management.

Wholesale Purchasing Decision Guide: Balancing Costs, Inventory and Customer Demand
1. Cost and Pricing Strategy
In terms of pricing strategy, Bluetooth scanners are usually sold at wholesale prices 10%-20% higher than 2.4G devices due to the higher cost of their chips (especially Bluetooth 5.0 and above). On the other hand, 433MHz devices are suitable for mass sales due to their mature technology and relatively low cost.
For price-sensitive customers (e.g., small retailers), it is recommended to prioritize the recommendation of cost-effective 2.4G devices. For medium and high-end customers (such as chain enterprises), we can focus on promoting Bluetooth 5.0 devices to enhance the overall profit margin.
2. Inventory structure optimization
In terms of inventory management, customers in first-tier cities prefer Bluetooth devices, which account for about 60% of the market share; while customers in second- and third-tier cities and industrial customers have a stronger demand for 2.4G and 433MHz devices. Therefore, it is recommended to adjust the inventory strategy on a quarterly basis according to the market situation:
Increase the stocking of Bluetooth and 2.4G devices during peak seasons (e.g., before e-commerce promotions).
In the low season, focus on digesting the inventory of 433MHz devices.
3. Customer Demand Prediction
Effective demand prediction can help you better serve your customers:
Scanning Frequency: Ask customers how many times they scan the code every day, and prioritize Bluetooth or 2.4G devices for high-frequency scenarios.
Usage environment: Understand the usage environment (e.g. indoor or outdoor, number of obstacles), in the scene with many obstacles or long distance, it is recommended to prioritize 433MHz devices.
Connected device type: Confirm the type of device that the customer needs to connect, if you need to connect to a cell phone, you must choose Bluetooth; if you are fixed to connect to a computer, 2.4G device is a good choice.
