Overview

The SCM Microsystems SCR3310v2.0-TypeC (now sold under IDENTIV) is a contact smart card reader with a USB Type-C connector, designed for Japan's e-Tax (online tax filing) and My Number card-based public authentication. It connects directly to modern laptops and desktops that have USB-C ports, eliminating the need for dongles. The interface runs at USB 2.0 speeds (480 Mbps), which is more than sufficient for reading and writing contact smart cards used in government authentication. This unit comes in a bulk package — no retail box or printed manual included.
The reader is PC/SC-compliant, meaning it works seamlessly with Windows, macOS, and Linux without additional drivers for basic card reading. For Japan's JPKI (Public Key Infrastructure) services, you'll still need to install the official driver software separately, but the hardware itself is recognized immediately. It's one of the most recommended models by Japanese municipalities and the National Tax Agency for home use.

Connectivity & Compatibility

Interface: USB Type-C (USB 2.0, 480 Mbps). The cable is permanently attached and approximately 1.5 meters long. If your computer only has USB Type-A ports, you will need a USB-C to A adapter (not included).
Operating systems: Windows 10/11, macOS 10.15 or later, Linux (with PC/SC support). The reader supports all ISO 7816 contact smart cards, including Japanese My Number card (JPKI), Resident Basic Register card, corporate ID cards, and credit card IC chips. It does NOT support Felica (NFC) or any contactless cards — it is contact-only. For government authentication, you must install the appropriate JPKI driver or middleware from the official portal.

Product Info

The SCR3310v2.0-TypeC is essentially the USB-C variant of the classic SCR3310, a best-selling model originally developed by SCM Microsystems. Today, IDENTIV manufactures it under the same part number. Pricing hovers around ¥4,400 on Japanese online retailers, making it an affordable entry-level choice. Warranty is typically 1 year through the seller. Since this is a bulk unit, no accessories (CD, manual, or carrying case) are included. All necessary software can be downloaded from IDENTIV's support site.
In the market, it occupies the entry-to-mid tier for contact smart card readers. While there are more expensive models with multi-interface (contact + contactless) support, the SCR3310v2.0-TypeC is the go-to device for My Number card users who need a reliable, simple, and officially recommended solution. It's widely available from major online retailers and some electronics stores in Japan.

Best Use Cases

Home tax filers: If you file your annual taxes via e-Tax using your My Number card, this reader is a perfect match. It eliminates trips to the tax office and works with all major tax preparation software. However, if you primarily use a smartphone for My Number portal tasks, you may not need a dedicated reader.
Remote government service users: More municipalities are allowing online applications for pensions, child allowances, and passport renewals using the My Number card. This reader makes those processes smooth from your PC. Just note that contactless services (e.g., NFC for transit) are not supported.
Business security-conscious pros: For corporate environments using smart cards for PC login or digital signatures, this reader integrates easily with Active Directory and PKI solutions. Its low bulk price makes it viable for multiple workstations. The cable length (1.5m) may be short for some desk setups — consider a USB extension if needed.
