What to Look for in an Iris Recognition Module
Choosing an iris recognition module for OEM integration is a decision that affects your product's security, user experience, and manufacturing cost for years. Before comparing specific products, understand the key criteria that separate a module you can ship from one that will create engineering headaches.
- False Acceptance Rate (FAR): The probability of incorrectly matching an unauthorized person. For access control, 10-6 is the minimum acceptable threshold; 10-7 is the target. Any vendor that cannot provide independently verified FAR numbers should be avoided.
- Physical dimensions: If you are integrating into a smart lock, kiosk, or wall-mounted terminal, the module must physically fit. Even a few millimeters can mean the difference between a clean integration and a redesigned enclosure.
- Interface: USB modules are easier to prototype with but limit your product design. FPC/UART modules offer the most flexibility for embedded products. Some modules offer both.
- Power consumption: Critical for battery-powered devices. A module drawing 5W is fine for wall-powered access panels but will kill a smart lock battery in weeks.
- SDK quality: The best hardware is worthless if the SDK is poorly documented, buggy, or limited to a single platform. Evaluate the SDK before committing to the hardware.
- Template capacity: On-device storage determines how many users the module can identify without external database lookups. For 1:N identification, more is better.
- Liveness detection: Essential for any security application. The module must distinguish a live iris from a printed photograph or displayed image.
1. HOMSH MD31 — Best Overall for Access Control
The MD31 is a complete iris recognition module designed for system integrators and OEMs building access control products, kiosks, and identity verification stations.
Key Specifications
- Dimensions: 57 x 45 x 25 mm
- Interface: USB 2.0 (Type-A)
- Power: Under 4W (USB bus-powered)
- FAR: 10-7
- FRR: Less than 0.1%
- Recognition speed: Under 1 second (1:N, 10,000 templates)
- Template capacity: 10,000 on-device
- Capture distance: 20–35 cm
- Imaging: Dual NIR cameras, 850nm wavelength
- Algorithm: PhaseIris on-device processing
- SDK platforms: Windows, Linux (ARM/x86), Android
- SDK languages: C, C++, Java, Python
- Liveness detection: Multi-frame NIR liveness, anti-spoofing included
- Certifications: IEC 62471 eye safety
Why It Stands Out
The MD31 hits the sweet spot between performance and integration simplicity. USB connectivity means any host system with a USB port can start evaluating in minutes. The SDK is genuinely comprehensive — not just a header file and a demo app, but full sample code for enrollment workflows, database management, and Wiegand output integration. At $235 to $299 per unit depending on volume, it undercuts most competing modules with equivalent specifications by 20 to 40 percent.
Best for: Access control panels, visitor management kiosks, time and attendance terminals, identity verification stations.
2. HOMSH MI30 — Best for Smart Locks and Embedded Devices
The MI30 is purpose-built for integration into space-constrained, battery-powered products — primarily smart locks, but also handheld identity devices and compact access readers.
Key Specifications
- Dimensions: 39 x 14.5 x 10 mm
- Interface: 20-pin FPC (UART + GPIO)
- Power: 3.2W active, under 50mW standby
- FAR: 10-7
- FRR: Less than 0.1%
- Recognition speed: Under 1 second
- Template capacity: 5,000 on-device
- Capture distance: 20–35 cm
- Imaging: Single NIR camera, 850nm
- Algorithm: PhaseIris on-device processing
- SDK platforms: Linux (ARM), Android
- SDK languages: C, Java
- Liveness detection: NIR liveness detection included
- Special features: Wake-on-approach GPIO, hardware match output, sub-300ms wake time
Why It Stands Out
At 39 x 14.5 x 10 mm, the MI30 is one of the smallest iris recognition modules available. The 3.2W power consumption and low-standby mode make it the only serious option for battery-powered smart locks that need to last months between charges. The hardware GPIO interface means it can work with simple MCU-based lock controllers without requiring a full Linux stack.
Best for: Smart door locks, compact access readers, handheld identity devices, embedded OEM products.
3. CMITech — Established Enterprise Grade
CMITech (formerly known as CustomMade Inc.) is a South Korean manufacturer with a long history in the iris recognition space. Their modules target enterprise and government markets with a focus on high-throughput identification.
General Profile
- Offers both standalone readers and OEM modules
- Strong presence in government identity programs
- FAR comparable to industry standard (10-6 to 10-7)
- Larger form factors typically suited to wall-mounted or turnstile applications
- SDK primarily targets Windows and Linux desktop platforms
- Higher price point reflecting enterprise market positioning
CMITech is a solid choice for large-scale government identity programs where the existing integration ecosystem matters more than unit cost. For smaller OEM projects or embedded applications, the larger form factors and higher pricing may be prohibitive.
4. IrisID — Wide Product Range
IrisID is a US-based iris recognition company (formerly LG Iris) offering a range of products from standalone access readers to OEM modules. They have significant deployments in border control and national ID programs.
General Profile
- Broad product line from handheld to wall-mounted readers
- OEM module available but targeted at larger integration projects
- Established relationships with government system integrators
- FAR in the 10-6 range for standard products
- Larger physical dimensions than newer compact modules
- Pricing tends toward the premium end of the market
IrisID is worth evaluating for projects that require a US-based vendor or need to integrate with an existing IrisID ecosystem. For new OEM products where size, power consumption, and unit cost are primary concerns, newer modules offer better specifications in smaller packages.
5. EyeLock — Innovative but Niche
EyeLock (now part of Corelight Technologies) has developed innovative iris recognition products including through-the-mirror and long-range capture systems. Their technology focuses on frictionless identification at a distance.
General Profile
- Unique capture-at-distance technology for walkthrough identification
- Products range from access readers to nano-sized modules
- Strong IP portfolio and patented capture methods
- Limited OEM module availability compared to dedicated module manufacturers
- Best suited for high-end commercial and enterprise applications
- Premium pricing reflective of advanced technology
EyeLock's at-a-distance capture technology is impressive for specific use cases like building lobbies and high-throughput access points. For standard OEM integration where the user positions themselves at a defined capture point, the technology premium may not be justified.

Buying Guide: How to Decide
Work through these questions to narrow your choice:
- What is your form factor constraint? If you are building a smart lock or compact device, the MI30 at 39 x 14.5 x 10 mm may be your only viable option. For wall-mounted readers and kiosks, the MD31 offers the best balance of features and ease of integration.
- What is your power budget? Battery-powered products require the MI30's 3.2W active / 50mW standby profile. Wall-powered products can use any module on this list.
- What platform does your host system run? If you need Python support or wide platform compatibility, the MD31's multi-language SDK is the strongest offering. For ARM Linux embedded systems, both HOMSH modules have native support.
- What is your volume and budget? At $235 to $299 per unit, HOMSH modules are 20 to 50 percent cheaper than competing modules with equivalent specifications. For products where BOM cost directly affects margin, this difference compounds at volume.
- Do you need vendor support during integration? HOMSH provides direct engineering support including custom firmware modifications for OEM customers. Larger vendors may route you through distribution channels with slower response times.
Why HOMSH Offers the Best Value in 2026
The iris recognition module market in 2026 has matured to the point where core accuracy (FAR/FRR) is comparable across serious vendors. The differentiators are now size, power consumption, SDK quality, price, and support responsiveness. HOMSH leads on all five of these dimensions for OEM integrators. The MD31 and MI30 together cover the full range of integration scenarios — from USB-connected access panels to battery-powered smart locks — with a consistent SDK and template format across both modules. For integrators evaluating their first iris module or OEMs looking to switch from a more expensive supplier, HOMSH is the strongest starting point in the current market.
