HOTUS R366-S 5.5-inch Slim Industrial PDA

R366-S 5.5-inch Industrial PDA | Qualcomm Octa-core with UHF, NFC, 2D Barcode & PSAM Slots

The R366-S industrial PDA bridges the gap between lightweight consumer devices and heavy-duty specialized terminals. Powered by a Qualcomm SM6115 octa-core processor (2.0GHz) and Android 16, it delivers smartphone-like usability with industrial-grade durability. What sets the R366-S apart is its modular optionality: UHF RFID for short-range bulk reading, NFC for tap-and-go workflows, a professional 2D barcode engine, and dual PSAM slots for financial or governmental security applications. All this in a lightweight body under 300g that fits comfortably in one hand.

Performance and Software Foundation

The Qualcomm SM6115 platform, built on an 11nm process, balances power and efficiency. Eight Kryo cores (running up to 2.0GHz) handle everything from real-time inventory lookups to background encryption tasks. Android 16 brings enterprise-friendly features: granular permission controls, work profiles, and long-term security updates. Our firmware stays close to AOSP, so existing MDM solutions (SOTI, VMware Workspace ONE, Samsung Knox) deploy without modification. Developers can use standard Android APIs for the optional scanners, NFC, and UHF module.

Wireless and Connectivity for Any Environment

The R366-S includes dual-band Wi-Fi (2.4GHz/5GHz) with 802.11ax (Wi-Fi 6) readiness, delivering higher throughput and better performance in congested warehouse networks. Bluetooth 5.0 connects to wireless printers, headsets, or external ring scanners. The 4G LTE modem comes in two variants: CN version for China/India (bands B1/B3/B5/B8, TDD B34/B38/B39/B40/B41) and EAU version for Europe, Middle East, Africa, Korea, Thailand, and Australia (additional bands B7/B20/B28). Fallback to 3G WCDMA and 2G GSM ensures connectivity even in remote areas. Multi-constellation GNSS (GPS, GLONASS, BeiDou) provides location accuracy down to 2 meters outdoors.

UHF RFID: Short-Range Bulk Reading

The optional built-in 40×40mm ceramic UHF antenna is designed for close-proximity applications where read range of 2 meters is sufficient – such as shelf inventory in retail, document tracking, or tool crib management. It supports FCC (902-928MHz), ETSI (865-868MHz), and SRRC-MII (840-845MHz, 920-925MHz) bands, complying with EPC Class 1 Gen 2 (ISO 18000-6C) tags. Unlike external sleds that add bulk, the integrated module keeps the device compact and ready for one-handed use. For warehouses requiring longer range (10-20m), consider our R366C-S model with Impinj E710; the R366-S is optimized for desktop-level or short-aisle RFID work.

2D Barcode Scanning: Down to 3mil

When RFID is not available or practical, the optional 2D imager captures standard and high-density barcodes with accuracy down to 3mil. This includes QR codes, Data Matrix, PDF417, and traditional 1D symbologies. The dual side-mounted SCAN buttons can be pressed with either thumb, reducing hand fatigue during long scanning sessions. Vibration and tri-color LED provide clear feedback even in noisy environments.

NFC and PSAM: Secure Identity and Payment

The NFC module (13.56MHz) supports ISO14443A/B, ISO15693, and common tag types including M1 (S50, S70) and CPU tags. Typical use cases include employee badge authentication, contactless access control, and NFC-enabled inventory checks. For high-security applications – such as electronic toll collection, government ID verification, or payment terminals – the R366-S is equipped with 2 PSAM slots (ISO/IEC 7816). These slots work in parallel, enabling multi-application secure access without swapping cards.

Rugged Yet Slim Design

Measuring 170mm × 79mm × 17.6mm and weighing under 300g, the R366-S is light enough for all-day wear on a belt holster but sturdy enough to survive drops and dust. The 5.5-inch IPS HD+ display (720×1440) is readable under direct sunlight, and multi-touch works with industrial gloves. The 4600mAh removable battery supports PD Fast Charging – ensuring reliable continuous operation. Operating temperature from -10°C to 50°C and 95% humidity tolerance covers cold storage, outdoor loading docks, and humid tropical warehouses.

Camera and Audio for Documentation

The rear 20MP autofocus camera with flash captures high-resolution proof-of-delivery photos, damage records, or shelf conditions. An optional front 8MP camera enables video calls for remote troubleshooting – reducing costly field service dispatches. Dual speakers, a microphone, and voice call support turn the device into a communication tool, not just a scanner.

Typical Deployments

Retail Inventory & Price Checks: Use NFC to identify shelf edges, scan barcodes with the 2D imager, or read UHF tags on high-value items – all in one device. The 4600mAh battery lasts a full shift of continuous use.
      Access Control & Time Attendance: Dual PSAM slots enable encrypted credential verification for employee badges. The device can act as a portable gate reader for events or construction sites.
      Pharmaceutical Traceability: Scan 2D data matrix codes on drug packages, verify with serial numbers, and sync to track-and-trace systems via 4G. UHF option reads bulk medication trays at short range.
      Library & Document Management: UHF tags on books and files can be inventoried by simply moving the R366-S along shelves – read range ≤2m is perfect for single-sided aisles. NFC handles patron cards.
      Field Service & Asset Inspection: Ultra-slim design (under 300g) reduces technician fatigue. Capture equipment photos with the 20MP camera, scan asset barcodes, and log GPS coordinates – all in one workflow.

Why Multi-Function Industrial PDAs (UHF + NFC + 2D + PSAM) Reduce Device Fleet Costs – R366-S Deep Dive

Many organizations still maintain separate devices: barcode scanners for inventory, NFC readers for access control, UHF readers for bulk counting, and smart card terminals for payments. The R366-S collapses all four roles into one rugged Android PDA. This convergence not only reduces upfront hardware costs but also simplifies training, spares management, and software integration. Below we analyze the ROI of switching to a universal device.

1. UHF RFID at ≤2m: Perfect for Desktop and Short-Range Applications

Not every RFID deployment needs 20-meter read range. For shelf-level inventory in retail stores, document tracking in offices, or tool crib management in factories, 2 meters is sufficient and actually prevents reading tags from neighboring areas (a common problem with high-power readers). The R366-S's integrated ceramic antenna provides reliable reads at close range without external sleds. One retail chain reduced inventory time by 70% using the UHF option to count tagged apparel on shelves, without picking up items individually.

2. Dual PSAM Slots – Enterprise-Grade Security

PSAM (Purchase Secure Access Module) slots are rarely found on handhelds outside specialized financial terminals. The R366-S offers 2 independent slots running ISO/IEC 7816 protocols. This allows simultaneous operation of multiple applications: a government ID card reader and a payment/loyalty applet – all without reinserting cards. For integrators building custom access control or vending solutions, this opens possibilities not available on consumer devices.

3. Android 16 + 4600mAh Battery = Full Shift Productivity

Older PDAs often compromise between performance and battery life. The R366-S's 4600mAh removable battery powers the octa-core processor and optional modules for a full shift of mixed use. Supported by PD Fast Charging, downtime is minimized. The removable design means swapping a fresh battery takes less than a minute – ensuring zero downtime for multi-shift operations.

4. Real-World Use Cases and Savings

Convention Center Access Control: A large venue replaced separate badge readers and inventory scanners with 50 units of R366-S. Each device now verifies attendee NFC badges, scans QR codes on tickets, and reads UHF tags on rented equipment – all in one pass. Hardware costs dropped by 40% and training time by 60%.
      Pharmacy Chain Inventory: Staff use the 2D imager for prescription barcodes, NFC for customer loyalty cards, and PSAM for insurance card verification. The single device streamlined checkout and back-office counting.

The R366-S is not just an incremental upgrade – it is a platform that adapts to your workflow. Choose only the modules you need today, and add others later. Sample units available for testing. OEM/ODM customization ready. Contact us for a demo unit or to discuss a tailored configuration for your industry.
