Handheld RFID Scanner​

At a time when the demand for digital management is constantly upgrading, the limitations of traditional barcode scanning equipment in complex scenarios are gradually emerging, and more and more industries are focusing on more efficient information collection solutions. As a product of the combination of radio frequency identification (RFID) technology and mobile terminals, RFID handhelds Scanner are becoming an important management tool in logistics, warehousing, manufacturing and other fields by virtue of the characteristics of non-contact reading, batch data processing, etc. In this paper, we will look at the technical principles, core functions, industry applications and other aspects of barcode scanning equipment. This article will be from the technical principles, core functions, industry applications and other dimensions, a comprehensive analysis of this new type of intelligent equipment, to help you quickly grasp its value and selection points.

RFID Handhelds: Redefining “Efficient Reading”

RFID handheld machine, also known as radio frequency identification handheld terminal, is a portable device that integrates RFID reading and writing modules and data processing functions. Differing from the traditional barcode scanning equipment, its core advantage lies in the non-contact reading ability: no need to align the commodity barcode scanning one by one, only in the effective range can batch read multiple label information, single reading distance up to 0.1-10 meters (depending on the type of label). This “non-visual, non-contact” mode of operation not only solves the identification problems caused by barcode defacement and obstruction, but also enhances the data collection efficiency by several times, which is especially suitable for the scenario of dense, high-frequency warehousing.

The appearance of the device is similar to ordinary handheld terminals, equipped with a color touch screen, battery life and exclusive RFID reading and writing engine, part of the model is compatible with barcode scanning function, to achieve the “dual mode” data collection. Its operating system is mainly based on Android and supports secondary development. Users can customize the management software according to their business needs to realize the whole process intelligence from data collection to system docking.

Core Functionality: More Than Just “Tag Reading” Management Upgrades

1. Contactless batch reading, breakthrough efficiency bottleneck

Traditional barcode scanning needs to be aligned one by one, processing up to 20-30 pieces of goods per minute; and RFID handheld can read dozens of tags in 1 second, with anti-metal, low-temperature and other special tags, even if the goods are in the stacking, packaging, or in dust, humidity and other harsh environments, but still be able to stably obtain information. For example, in the warehouse inventory, the staff only need to hold the device in the shelves to move quickly, you can complete the information collection of hundreds of goods, time-consuming than the traditional way to shorten the time by more than 70%. 2.

2. Real-time Data Synchronization, Building Intelligent Management Closed Loop
Through Wi-Fi, 4G and other network modules, RFID handhelds can upload the collected data to the management system in real time, and synchronously update the information of inventory, asset location, and logistic trajectory, etc. Take warehouse management as an example. Taking warehouse management as an example, scanning the label of goods can be automatically associated with the order information when entering the warehouse, and when leaving the warehouse, the equipment can automatically check the match between the goods and the order, so as to avoid manual misdelivery; combined with the backstage management software, it can also realize the functions of inventory early warning and cargo space planning, so as to make the management decision more precise. 3.

3. Multi-scenario adaptation to meet differentiated needs
equipment supports a variety of RFID tag types (low-frequency LF, high-frequency HF, ultra-high-frequency UHF), different frequency bands correspond to different reading distance and application scenarios:
High-frequency HF (13.56MHz): short reading distance (0.1-0.5 meters), suitable for accurate reading of medicines, electronic components and other small goods information;

Ultra-high frequency UHF (860-960MHz): reading distance is long (1-10 meters), support for batch reading, commonly used in logistics parcels, warehousing goods management;

Specialty labels: metal-resistant labels can be attached to the surface of metal products, low-temperature resistant labels are suitable for cold chain scenarios, and washable labels can be used in apparel, fresh produce and other industries that require cleaning.

1. Logistics and express delivery: smarter sorting and distribution
In the express delivery sorting process, the traditional scanning code needs to manually look for the face sheet, low efficiency and prone to error; the use of RFID handheld machine, just put the parcel into the sorting basket, the equipment can batch read all the parcel labels, automatically match the sorting path, the sorting efficiency to improve more than 50%. When dispatching parcels, the equipment can synchronize the location of parcels in real time, and the customer's signing information can be uploaded to the system in seconds to avoid disputes over lost parcels. According to the data of an e-commerce warehouse, after the introduction of RFID handheld machine, the daily handling volume of parcels in a single warehouse has increased by 30%, and the labor cost has decreased by 25%.

2. Supermarket Retail: Inventory and Inventory Management Innovation
Traditional manual inventory needs to be scanned piece by piece, and it usually takes 2-3 days for a medium-sized supermarket to complete the inventory of the whole store; RFID handheld machines can complete the scanning of the whole store within 2 hours, and the out-of-stock rate of shelf goods is reduced by 40%. In addition, the equipment supports merchandise anti-theft warning: when the unchecked-out merchandise is close to the exit, the system automatically triggers an alarm, and with the electronic price tag synchronization function, it can also realize real-time update of promotional information to enhance the operational efficiency of the store.

3. Healthcare: Precision Nursing and Consumables Management
In the hospital scenario, RFID handhelds can be used for patient wristband identification and drug and consumables tracking: when the nurse checks the room, scanning the wristband can retrieve the patient's medical records and medication records, avoiding manual checking errors; in the drug warehouse, the equipment automatically identifies the drugs with close to expiration date, reminding the management staff to prioritize the use of the drugs to reduce the waste of medical consumables. The practice of a tertiary hospital shows that after the introduction of the device, the nursing error rate dropped by 60%, and the inventory time of consumables was shortened by 80%.

4. Manufacturing industry: production traceability and quality control
In production line management, RFID handhelds can collect real-time accessory information, correlate production processes and operators, and realize full-process product traceability. For example, in automobile manufacturing, the equipment reads the engine parts label, automatically verifies the matching degree of parts models and orders, and prevents misloading and leakage; warehouse links, batch reading raw material labels, and automatically generates in and out of the warehouse report, inventory accuracy rate is increased to more than 99%.

5. Warehouse management: from “manual search for goods” to “intelligent positioning”
Traditional warehousing relies on paper documents or barcode scanning, time-consuming and error-prone search for goods; RFID handheld combined with the goods position labels, real-time display of the location of goods, support for “find goods by map”. The RFID handheld machine combined with the goods position label can display the location of goods in real time and support the function of “finding goods according to the map”, which can increase the efficiency of picking goods by 40%. During inventory, the equipment automatically generates difference reports, and managers can locate misplaced goods through the background, shortening the inventory turnover cycle by more than 20%.
