vlg RFID

　　I. Core Product Categories (Added Details for Sub-Scenario Adaptation)

　　VLG RFID products revolve around "precise frequency band matching + industry customization." Based on the three main categories of HF (High Frequency), UHF (Ultra High Frequency), and combined types, industry-specific models and functions are added:

　　1. High Frequency (HF) RFID Hardware (13.56MHz)

　　Core Models and Features:

　　Medical Dedicated Model (VLG-HF-Med): Uses medical-grade PET substrate, supports 121℃ steam sterilization (no performance degradation after 30 minutes), complies with ISO 13485 certification, storage capacity 256B-2KB (encrypted storage of consumable batch number and expiration date), suitable for tracking disposable consumables such as syringes and surgical dressings;

　　Consumer Retail Model (VLG-HF-Retail): Ultra-thin design (thickness ≤0.8mm), can be embedded in clothing tags and cosmetic packaging boxes, supports NFC mobile phone direct reading (no special equipment required), compatible with ISO 14443 A/B Protocol adapted for self-checkout scenarios;

　　Industrial grade (VLG-HF-Industrial): Temperature resistant -40℃~85℃, oil resistant (compliant with ISO 10993-1), used for lifecycle marking of small industrial components such as motors and bearings, with a reading distance of 0.3-1.2 meters.

　　Key parameter upgrades: Data transmission rate increased to 848kbps (traditional HF is 424kbps), enhanced anti-interference capability (false reading rate ≤0.05% in 2.4GHz WiFi environment), tag lifespan ≥5 years (normal temperature environment).

　　2. Ultra-High Frequency (UHF) RFID Hardware (860-960MHz)

　　Core Models and Features:

　　**Anti-Metal Strong Adhesion Type (VLG-UHF-Metal):** Uses a ceramic substrate + LDS laser-engraved antenna (borrowing from VLG GNSS antenna technology). Even after being adhered to a metal surface, the reading distance remains 3-8 meters (traditional anti-metal tags only 1-3 meters). Suitable for container, machine tool, and tracker equipment shell markings (works with a tracker to achieve dual tracking of "location + identity").

　　**Flexible and Bendable Type (VLG-UHF-Flex):** The substrate is TPU flexible material with a bending radius ≤5mm. Water-resistant (performance degradation ≤3% after 50 machine washes). Used for flexible assets such as fabrics and leather (e.g., waterproof labels for logistics parcels, garment traceability).

　　**Long-Range Reader (VLG-UHF-Reader-Pro):** Gain 12-18dBi (can be extended to [specific range] with a VLG signal amplifier). 25dBi), supports simultaneous multi-tag recognition (≤80 tags/second, compared to 50 tags/second for traditional models), and has an interface compatible with Ethernet/4G/NB-IoT (directly connects to VLG 4G modules for real-time data upload).

　　Key parameter upgrades: Optimized multi-tag anti-collision algorithm (dynamic time-slot ALOHA + binary tree algorithm), improving recognition efficiency by 60% in densely labeled environments (such as warehouse shelves), and achieving ≥98% reading stability in outdoor high-light environments (10000 lux illuminance).

　　3. Combined RFID Solutions (New Cross-Product Collaboration Model)

　　**“RFID+Tracker” Asset Tracking Kit:** VLG-UHF-Metal tag (attached to assets) + Tracker (real-time positioning) + UHF reader (area identification). The tag and Tracker are linked via a UART interface. When an asset enters the reader's coverage area (e.g., at the workshop entrance), the Tracker's positioning data is automatically synchronized, solving the blind spot problem of "satellite positioning to find the area, RFID to find the specific asset" (e.g., tracking equipment underground in mines).

　　**“RFID + Temperature and Humidity” Cold Chain Kit:** VLG-UHF-Flex tag (integrated temperature and humidity sensor) + 4G reader. The tag collects the temperature of goods in real time (accuracy ±0.3℃) and uploads it to the cold chain platform via the VLG 4G module. It automatically alarms when the temperature exceeds a threshold (e.g., fresh produce ≤0℃), suitable for vaccine and seafood transportation.

　　**“HF RFID+NFC+WiFi” Retail Kit:** VLG-HF-Retail tag (for goods) + Desktop reader (for checkout) + WiFi antenna. Consumers use their mobile phones to touch tags with NFC to view product traceability information. The checkout reader quickly identifies items (≤0.5 seconds/item) and supports batch scanning of multiple items (compatible with supermarket self-checkout).

　　II. Core Technical Features (Enhancing VLG Hardware Capability Migration)

　　1. Tag Antenna and Signal Optimization (Related to VLG RF Technology)

　　Miniaturized Antenna Design: HF tags utilize VLG miniature PCB antennas (area ≤10mm×8mm), while UHF tags employ LDS laser-engraved antennas (accuracy ±0.01mm), reducing size by 40% compared to traditional etched antennas, allowing for embedding in confined spaces such as tracker housings and medical consumable packaging;

　　Weak Signal Enhancement: The reader incorporates VLG adaptive gain technology (migrated from the signal amplifier AGC logic). In metal-dense environments (such as industrial workshops) or long-distance scenarios (such as logistics warehouses), dynamic gain adjustment (3-25dB) extends the reading distance by 2-3 times, increasing the success rate of weak signal area identification from 75% to 99%;

　　Anti-interference Upgrade: Built-in "dual-band filtering + digital signal processing (DSP)" module suppresses interference from industrial equipment (inverters, motors), WiFi/Bluetooth, etc. Interference attenuation in the 200MHz-2.7GHz band is ≥55dB (compared to 40dB for traditional models), and the tag misread rate is ≤0.03%.

　　2. Cross-Product Collaboration Capabilities (Deep Integration with the VLG Ecosystem)

　　* **Track Collaboration:** VLG-UHF-Metal tags are affixed to industrial assets (such as welding robots). The Tracker has a built-in UHF identification module. When assets move, the Tracker reads tag information (such as asset ID and maintenance cycle) in real time and uploads it to the IoT platform along with GNSS positioning data, achieving integrated "identity identification + location tracking + status management" (in a car factory application, asset inventory efficiency improved by 90%).

　　* **Communication Module Collaboration:** The reader integrates a VLG NB-IoT/4G module. Identified data is uploaded directly to the cloud without an intermediate gateway (latency ≤150ms). When the network is offline, it can store ≥500,000 data entries locally (compared to only 100,000 entries for traditional readers), making it suitable for logistics stations in remote areas.

　　* **IoT Platform Integration:** Supports access to the VLG IoT cloud platform and third-party systems (such as SAP and Yonyou ERP), providing a standardized SDK (development cycle ≤1 week) and allowing customization of data fields (such as those for medical consumables). (Data includes "Number of Disinfections" and "User"), generating traceability reports, inventory alerts, and other visualized data.

　　3. Industry Compliance and Durability (Supplementary Sub-Standards)

　　Medical Sector: The HF medical version is FDA certified (21 CFR Part 820) and can be used for labeling implantable medical devices (such as cardiac stents). Label sterilization methods support EO ethylene oxide and gamma ray sterilization.

　　Industrial Sector: The UHF anti-metal version complies with ISO 18000-6C Type C standards, is vibration-resistant (10-2000Hz, 20G acceleration), and salt spray-resistant (1000 hours, 5% NaCl), suitable for marine shipping container labeling.

　　Consumer Sector: The HF retail version complies with EU CE-RED and US FCC ID certifications. The material meets OEKO-TEX® Standard 100 (free of harmful chemicals), suitable for children's clothing labels.

　　III. Typical Application Scenarios (New Sub-Industry Cases)

　　1. Medical Consumables Full Lifecycle Traceability (HF RFID)

　　Solution Combination: VLG-HF-Med tags (attached to consumable packaging) + wall-mounted HF readers (disinfection room/operating room) + VLG 4G module + hospital HIS system;

　　Application Logic:

　　Consumables are written with batch number, expiration date, manufacturer, etc., at the factory. Upon arrival at the hospital, the reader scans and registers the consumables, linking them to the department's requisition permissions;

　　Before use in the operating room, the system scans again, automatically verifying "expiration" and "suitability for the patient." After use, it is scanned and marked "used" to prevent reuse;

　　Data is uploaded to the HIS system via the VLG 4G module, generating a consumable usage ledger, achieving full traceability from "procurement - warehousing - use - disposal";

　　Results: After implementation in a tertiary hospital, the number of expired consumable usage events decreased to 0, consumable waste rate decreased by 30%, and traceability query time was reduced from... One hour reduced to 10 seconds.

　　2. Industrial Warehousing "RFID + Tracker" Smart Inventory Management (UHF RFID)

　　Solution Combination: VLG-UHF-Metal Tags (attached to shelves/goods) + Tracker (equipped with AGVs) + UHF Reader (warehouse entrances/exits) + VLG IoT Platform;

　　Application Logic:

　　When goods enter the warehouse, the reader scans the tags, binding the shelf location with the Tracker's positioning data to generate an electronic storage location map;

　　AGVs, equipped with Trackers and small readers, automatically scan shelf tags while moving, comparing them with the system's storage location information. If misplacement is detected (e.g., goods placed on the wrong shelf), an immediate alarm is triggered;

　　During monthly inventory checks, the system automatically generates an inventory list, eliminating the need for manual verification. Abnormal goods (e.g., missing or expired) are automatically marked;

　　Results: After implementation in an electronics factory, warehouse inventory time was reduced from 3 days to 4 hours, the storage location misplacement rate decreased from 8% to 0.5%, and AGV scheduling efficiency improved by 40%.

　　3. Smart Retail "RFID+NFC" Self-Checkout (HF RFID)

　　Solution Combination: VLG-HF-Retail Tags (attached to products) + Self-Checkout Counter (integrated HF reader) + Consumer Mobile Phone NFC + VLG WiFi Antenna;

　　Application Logic:

　　Products are labeled with name, price, and specifications at the factory. After selecting products, consumers place them on the self-checkout counter, where the reader identifies them in batches within 1 second (supporting simultaneous scanning of 10 items);

　　The checkout counter connects to the mall's system via the VLG WiFi antenna to generate an order. Consumers can confirm product information and complete payment by touching the tag with their mobile phone's NFC;

　　After payment, the tag is automatically deactivated (to prevent duplicate transactions), and the system synchronously updates inventory data. Low-inventory items (such as cosmetics) are automatically alerted for restocking;

　　Results: After implementation in a chain supermarket, self-checkout efficiency increased by 3 times (average checkout time reduced from 2 minutes to 40 seconds), cashier labor costs decreased by 50%, and inventory accuracy reached ≥99.2%.
