Identiv SCR3310v2.0

Recommended

Identiv·USB

Overview

The SCR3310v2.0 is the second-generation version of Identiv's flagship contact reader, featuring a revised USB controller that delivers noticeably faster card read times compared to the original SCR3310. The physical footprint is reduced by 15%, and the cable has been reinforced for higher-durability field use. Like its predecessor, it is fully CCID-compliant and requires no additional drivers on modern operating systems. It is the recommended reader for new deployments where raw throughput matters.

Requirements

USB-A port (USB 2.0 or higher)
PC/SC daemon (pcscd on Linux/macOS, built-in on Windows 10+)
Python 3.9+ with pyscard
ECOWAS biometric identity card

Setup Guide

Connect the Reader

Steps

Insert the SCR3310v2.0 USB cable into any available USB-A port.

The OS will auto-detect the CCID device using its built-in driver.

The green LED indicates standby; amber indicates a card is placed.

No extra driver software is needed on Windows 10+, macOS 12+, or Ubuntu 20.04+.

Configure PC/SC

Steps

macOS: `brew install pcsc-lite && brew services start pcsc-lite`

Ubuntu/Debian: `sudo apt-get install -y pcscd pcsc-tools && sudo systemctl enable --now pcscd`

Install pyscard: `pip install pyscard`

Confirm: `python -c "from smartcard.System import readers; print(readers())"`

Verify Detection

Steps

Run `pcsc_scan` on Linux/macOS to list attached readers.

The v2.0 appears as `Identiv SCR3310v2.0 [CCID Interface]`.

Place a DREWQ on the reader and confirm LED changes to amber.

Hit `GET /card/status` on the API to confirm `card_present: true`.

Test with the API

Steps

Launch the FastAPI server: `uvicorn main:app --reload`

POST to `/card/scan` with `doc_number`, `date_of_birth`, and `expiry_date`.

Expect a 200 response with citizen fields populated.

Check the scan log in the dashboard or via `GET /scans`.

Troubleshooting

Reader shows as SCR3310 (original) in pcsc_scan

Both models share a similar USB VID/PID on some firmware versions. This is cosmetic — functionality is identical. You can confirm the model via `lsusb -v | grep -A5 Identiv`.

Intermittent disconnections during scanning

Use the reader directly on the host machine rather than through a USB hub. Hubs without external power can cause voltage drops that disconnect the reader mid-read.

Slow read times despite using v2.0

Ensure the USB port supports USB 2.0 Hi-Speed. Legacy USB 1.1 ports limit throughput. Check your USB controller in Device Manager (Windows) or System Information (macOS).
