The BS2A-OAPWB is BioStation 2a, a newer-generation Suprema biometric terminal introduced as part of the BioStation 2a platform.

It should not be confused with the older BioStation 2 BS2-OHPW. Suprema officially announced the discontinuation of BS2-OHPW and designated BS2A-OAPWB as its successor.

Product Overview

The Suprema BioStation 2a BS2A-OAPWB is a professional biometric terminal designed for access control and time-attendance environments requiring fingerprint recognition together with broad RFID and mobile credential support.

Built around a 1.5 GHz quad-core processor with 16 GB Flash and 2 GB RAM, BioStation 2a provides substantial credential and event-log capacity while supporting modern network and access-control interfaces.

The BS2A-OAPWB configuration is particularly important to identify correctly because it adds 2.4 GHz Wi-Fi and expanded RFID support compared with the BS2A-ODPB variant.

BioStar 2 Compatibility

BioStation 2a was introduced with support from:

• BioStar 2 version 2.9.4 or later
• BioStar 2 Device SDK version 2.9.4 or later
• Suprema G-SDK version 1.6.0 or later

For an existing Suprema deployment, customers should verify their current BioStar software, firmware, SDK and system architecture before adding or replacing devices.

Applications

Suitable for appropriately designed systems in:

• Corporate offices
• Commercial buildings
• Warehouses
• Manufacturing facilities
• Educational facilities
• Hospitality environments
• Staff entrances
• Restricted areas
• Employee access control
• Time and attendance systems
• Multi-credential security environments

Suitability depends on the complete access-control system design and security requirements.

Purpose of Use

The BS2A-OAPWB can authenticate users through supported fingerprint, RFID and mobile credentials and communicate authentication events to a properly configured access-control or attendance environment.

It is a professional system component rather than a complete access-control installation by itself.

Locks, exit devices, controllers, power supplies, network infrastructure, software configuration and other components may be required depending on the project.

BS2A-OAPWB vs BS2A-ODPB

Both belong to the BioStation 2a family, but they should not be treated as identical SKUs.

The BS2A-OAPWB provides broader RFID compatibility, including HID Prox and iCLASS SE/SR/Seos, and supports 2.4 GHz Wi-Fi.

The BS2A-ODPB has a different RFID configuration and does not provide built-in Wi-Fi.

Customers should therefore order using the exact Suprema model number required by their credential environment.

Upgrade Guidance for Older BioStation 2 Users

Customers currently using the older BioStation 2 BS2-OHPW should note that Suprema officially designated BS2A-OAPWB as its successor.

Suprema announced the older BS2-OHPW model's discontinuation on 9 May 2024, with:

Last Order: 9 November 2024
End of Service: 9 November 2027
Official Successor: BS2A-OAPWB

This manufacturer-defined successor relationship makes BS2A-OAPWB particularly relevant when planning replacement or modernization of an older BS2-OHPW deployment.

Compatibility with an existing installation should nevertheless be reviewed before replacement because hardware, software, credentials, wiring and system configuration can differ.

Things to Verify Before Ordering

Please confirm:

• Exact model required is BS2A-OAPWB
• Existing RFID/card technology
• Fingerprint authentication requirements
• Mobile credential requirements
• Wi-Fi requirement
• Ethernet or PoE requirements
• Existing Suprema/BioStar environment
• Required BioStar software compatibility
• Door hardware and access-control architecture
• Power requirements
• Indoor/outdoor installation conditions
• Required accessories
• Integration responsibilities
• Quantity
• Current availability and lead time

For replacement of an older BioStation 2 installation, do not assume that every existing configuration can be transferred without review.

Buyer Guidance

Choose BS2A-OAPWB when the application specifically requires its broader RFID support and/or built-in Wi-Fi capability.

If those features are unnecessary, another BioStation 2a configuration may be sufficient.

For an existing access-control system, verify credential technology and system compatibility before purchasing rather than selecting solely by appearance or product-family name.

Why NEOTECH® UAE?

At NEOTECH®, product information is not treated as something we publish once and forget. We improve it whenever we discover a clearer, safer, or more useful way to serve the customer.

That means reviewing manufacturer information, correcting outdated specifications, identifying product lifecycle status, distinguishing exact model configurations, clarifying predecessor and successor relationships, and updating buyer guidance when better information becomes available.

For the Suprema BS2A-OAPWB, this is particularly important because BioStation 2 and BioStation 2a are different generations, and the individual BioStation 2a variants have different RFID and wireless capabilities.

Our objective is simple: help customers understand what they are buying, whether it is right for their requirement, and what should be verified before they pay.

Learn First. Decide Second.
