- UPEK customer report about the deal with IBM
- Review from TrustedReviews of the fingerprint scanner
- A (Russian) project that provides support for a (different model) of fingerprint scanner (also a USB device, though)
- Discussion of the T42/T24p fingerprint scanner on the Linux Biometrics site
