Card Reader Promag PCR-330A

The Promag PCR-330A is a compact RFID card reader with a slot and USB keyboard-mode connectivity. Operating at 125 kHz, it reads compatible proximity cards and is designed for integration into access control and data-entry systems. Its small footprint allows installation on counters or inside kiosks where a reliable, wired card-reading interface is required.

Advantages

The reader provides USB keyboard output for easy plug-and-play integration with PCs and terminals without additional drivers. Its slot design supports swiped or inserted cards and the 125 kHz RFID frequency ensures compatibility with common low-frequency proximity cards. The device's compact dimensions (65 × 23 × 100 mm) make it suitable for constrained spaces and mounting in user-facing environments.

Suitable for

• Access control terminals and door-entry systems
• Point-of-sale or kiosk user identification
• Employee time and attendance recording
• Systems requiring simple USB keyboard-mode card input

Key specifications

• Model: Promag PCR-330A (MPN: PCR330A-00)

• Interface: USB (keyboard mode)
• Form factor: slot reader
• Dimensions (W×H×D): 65 × 23 × 100 mm

How to use

Connect the device to a computer or terminal using the USB cable; the reader presents card data as keyboard input, so no special drivers are typically required. Insert or swipe a compatible 125 kHz proximity card through the slot; the reader will transmit the card ID to the connected system as keystrokes. Configure the host application (access control software, POS, or timekeeping system) to accept keyboard-mode card data and map the received input to the appropriate user record or action.

Recommendations

Place the reader on a stable surface or mount it where users can easily insert cards. Ensure connected systems are set to accept keyboard input and verify card compatibility with 125 kHz RFID formats. For reliable operation, avoid exposing the device to extreme moisture or temperatures and keep the slot free of debris.
