Legacy Fingerprint Driver

If you're in the market for a USB fingerprint scanner, the Hamster IV and Hamster Plus are two devices worth considering. These scanners are designed to help you capture high-quality fingerprint images that can be used for various purposes. Whether you need to verify someone's identity or secure access to your computer or network, these scanners can get the job done.

To use a Hamster IV or Hamster Plus scanner with your application, you'll need to install a legacy driver. This driver is what allows the scanner to communicate with your computer, and it's easy to install by simply plugging in the device to your USB port. Keep in mind, though, that if you're using Windows 7 or later, there's a chance that the legacy driver may be overwritten by the Windows Biometric Framework (WBF) driver during an update.

To avoid this issue, it's a good idea to update the SDK dll. For example, the sgfplib.dll from FDx SDK Pro is an SDK library that can help ensure a smooth and stable interface between the scanner and your application. Once you have everything set up and installed correctly, you'll be able to capture fingerprint images quickly and easily with your Hamster IV or Hamster Plus scanner.
