Compact Rugged Keypad PDA for Field Data Collection V400

The V400 is built for field data collection tasks where physical number entry matters more than a large screen. It fits route records, inventory checks, counter service, and simple app workflows where workers need repeatable key input. Its compact 4-inch body, 21-key keypad, optional 2D scanner, and optional NFC help buyers decide whether a small keypad PDA is enough before moving to a larger scanner device.

Introduction

Compact Keypad PDA for Scanning and Data Entry

The V400 fits buyers who still need real keys for repeated field input. Route workers, counter staff, warehouse operators, and service teams may enter quantities, codes, confirmations, or task shortcuts faster with a compact keypad than with a full-touch PDA.

Its value is not screen size; it is control density in a smaller handheld. Optional scanning and NFC make sense when the same keypad-led task also needs label capture or card checks, but the product should stay positioned as a compact data collection PDA.

A buyer should test the keypad routine with the real app before choosing a larger scanner device. If the job needs long forms, high-frequency scan handling, or handle-style RFID reading, SWELL can compare a different rugged handheld.
