All-in-One Mobile Data Collection Terminal
Traditional field operations often require several separate devices for barcode scanning, RFID reading, communication, printing and data entry. This industrial PDA combines these functions into a single handheld terminal.
Workers can scan a barcode, read an NFC or HF RFID tag, enter information through the physical keyboard, capture images with the integrated camera, determine their location using GPS and transmit the collected data through 4G or Wi-Fi.
The integrated design can simplify equipment management and improve operational efficiency in warehouses, retail stores, logistics operations, hospitals, utilities and government projects.

| Mobile computing | Android-based PDA |
| RFID/NFC | 13.56 MHz HF RFID/NFC reader and writer |
| Barcode | 1D and 2D barcode scanning |
| Cellular communication | 2G/3G/4G |
| Wireless connectivity | Wi-Fi and Bluetooth 4.0 |
| Positioning | GPS |
| Data capture | Camera, touchscreen and physical keyboard |
| Printing | Built-in 58 mm thermal printer |
| Smart card | Dual PSAM card support |
| Data storage | 8 GB ROM, expandable up to 32 GB |
| Battery | 7.4 V 3200 mAh lithium-ion battery |
13.56 MHz NFC and HF RFID Reading and Writing
The integrated NFC/RFID module operates at 13.56 MHz and supports a range of commonly used high-frequency contactless technologies. It can be used for RFID label identification, card reading, data writing and short-range NFC applications.
Supported protocols listed for the device include ISO 14443A/B, ISO 15693, Sony FeliCa and MIFARE. The NFC function also supports reading and writing as well as peer-to-peer data transfer.
This makes the terminal suitable for applications involving employee identification cards, access-related workflows, asset tags, product identification, smart cards and other HF RFID applications.
| RFID/NFC Feature | Specification |
|---|---|
| Frequency | 13.56 MHz |
| Technology | HF RFID / NFC |
| ISO 14443 | A/B |
| ISO 15693 | Supported |
| MIFARE | Supported |
| Sony FeliCa | Supported |
| Operation | Reading and writing |
| NFC P2P | Supported |
Important: This device uses 13.56 MHz HF RFID/NFC technology. It is not a long-range UHF RFID reader. If your application requires reading UHF tags from several meters away for bulk warehouse inventory, a dedicated UHF RFID handheld terminal should be considered instead.
Integrated 1D and 2D Barcode Scanning
In addition to RFID and NFC, the handheld PDA can be equipped with an integrated 1D laser scanner or 2D image scanner. This allows businesses to select the scanning technology that best matches their application.
Barcode scanning can accelerate product receiving, inventory counting, order verification, asset identification and logistics operations. Instead of manually entering product codes, operators can scan identification data directly into the mobile application.
The combination of barcode and RFID capabilities is particularly useful when a business works with both traditional barcodes and contactless RFID tags.
4G Connectivity for Real-Time Field Operations
The terminal supports 2G, 3G and 4G mobile communication, allowing collected information to be transmitted to a remote server or business application while workers are away from fixed workstations.
Supported cellular bands listed on the original specification include LTE-FDD B1/B3/B8, LTE-TDD B38/B39/B40/B41, WCDMA Band 1/8 and additional regional network bands.
This connectivity can support workflows such as real-time inventory updates, delivery confirmation, mobile inspections and remote field data collection.
Before deployment, customers should verify the supported frequency bands against the mobile networks used in their target country or region.
Wi-Fi, Bluetooth and GPS
The industrial PDA also provides multiple wireless communication options for different working environments.
Wi-Fi can be used for local wireless networks in warehouses, stores, factories and offices. Bluetooth 4.0 allows communication with compatible peripheral devices. GPS provides location information for mobile operations where geographic positioning is required.
Together with 4G cellular communication, these connectivity options allow the device to move between indoor and outdoor working environments without relying on a single communication method.
| Connectivity | Application |
|---|---|
| 4G | Mobile data communication |
| 3G / 2G | Regional cellular connectivity |
| Wi-Fi 802.11b/g | Local wireless networks |
| Bluetooth 4.0 | Wireless peripherals |
| GPS | Location and field tracking |
Rugged Design for Industrial Work
The terminal is designed for mobile and industrial environments rather than ordinary consumer smartphone use. Its physical keyboard, integrated scanning options and durable enclosure are intended for operators who frequently handle the device during repetitive data collection tasks.
The product specification lists IP65 protection and CE certification. The physical keyboard contains 29 keys and is designed for fast data entry even when workers prefer tactile buttons over touchscreen input.
The device measures approximately 209 × 83 × 49 mm and weighs about 508 g including the battery.
For deployment in demanding environments, customers should confirm the exact environmental protection, operating temperature and drop-resistance specifications for the required configuration before placing an order.
4-Inch Touchscreen and Physical Keyboard
The 4-inch IPS touchscreen provides an 800 × 480-pixel resolution and supports touch operation. Its relatively compact size keeps the terminal portable while providing enough screen space for common data collection applications.
Unlike smartphones that depend primarily on touchscreen input, this PDA also provides a 29-key physical keyboard. This can be useful for workers who need to enter quantities, item numbers, confirmation codes or other information repeatedly.
The combination of touchscreen and physical keys gives application developers more flexibility when designing mobile workflows.
Built-In 58 mm Thermal Printer
A built-in 58 mm thermal printer is available directly inside the handheld terminal. With a maximum listed printing speed of up to 80 mm/s, it can be used for immediate printing at the point of operation.
For example, warehouse operators can print transaction records, retail staff can print receipts or labels, and logistics personnel can produce simple delivery or confirmation documents without returning to a fixed printer.
An integrated printer can reduce the need to carry a separate portable printing device and can make certain field workflows more efficient.
Camera for On-Site Documentation
The integrated rear camera provides an additional method of capturing visual information during field operations. Depending on the application, workers can use the camera to document products, equipment, packages, locations or inspection conditions.
When combined with barcode/RFID identification and GPS information, photographs can become part of a complete digital field record.
For example, an inspection application could associate a scanned asset ID, GPS position, inspection result and photograph with the same work order.
Dual PSAM Card Support
The terminal supports two PSAM card channels and ISO 7816-1/2/3/4 protocols. PSAM functionality can be useful in applications requiring secure smart-card operations or dedicated card-based authentication and transaction workflows.
This feature expands the terminal beyond simple barcode and RFID data collection and makes it suitable for specialized payment, identification and secure card applications.
The exact security functions depend on the application software, PSAM configuration and card implementation. System integrators should confirm their card requirements before deployment.
RFID Handheld Terminal vs. Standard Mobile PDA
A standard Android smartphone can handle communication and basic data entry, but it normally requires external accessories for professional barcode, RFID, PSAM or receipt-printing functions.
An industrial RFID PDA integrates these capabilities into one purpose-built terminal.
| Capability | Standard Smartphone | RFID Handheld PDA |
|---|---|---|
| Android applications | Yes | Yes |
| Touchscreen | Yes | Yes |
| 4G communication | Usually | Yes |
| Barcode scanning | Optional accessory | Integrated option |
| HF RFID/NFC | Depends on model | Integrated |
| Physical keyboard | Rare | 29 keys |
| Thermal printer | External | Built-in |
| PSAM | Rare | 2-channel support |
| GPS | Usually | Yes |
| Industrial protection | Limited | IP65 listed |
| Field data collection | Basic | Designed for professional use |
The main advantage is not simply the number of functions, but the ability to combine them into one workflow and one portable device.
