По размеру особых проблем не представляет: вот один в форме УСБ драйва.

75mm(L) x 24mm(W) x 13mm

Fingerprint security
Notebooks

By Stephen Regenold

The average office worker juggles a dozen or more passwords and user names for various e-mail accounts, Web sites, online banks and network log-ins. For some relief, IBM Corp. and Fujitsu Computer Systems are offering an alternative to password overload. The two companies have added fingerprint sensors to their notebook computer lines, giving users a more expedient method of entering passwords, replacing the recalling and typing in of a password with the swiping of a finger.

The IBM ThinkPad T42, for example, has a fingerprint reader on its on the wrist rest, below the arrow keys. Using a software wizard, a new user sets up a security account and then swipes a finger over the reader to load their unique biometric information. You can scan and store multiple fingerprints from your hands and from other people who may need to access the computer. A password can also be set up along with the fingerprint as a backup.

Fujitsu offers a similar fingerprint reader with its LifeBook S7000 notebook. The tiny, 3.3-pound notebook has a fingerprint reader positioned between the right- and left-mouse buttons, and the sensor doubles as a scrolling key for navigating documents.

Both companies' fingerprint sensors can be set up to override log-in passwords. When logging in to Microsoft Windows after startup, for example, LifeBook S7000 and ThinkPad T42 users can swipe a finger over the sensor to access the desktop. Accompanying software from both companies can set up this same kind of convenient access with Web sites, e-mail programs and other applications that require passwords.

Security bonus

In addition to the convenience factor, fingerprint readers can offer a higher level of security, as your fingerprint is completely unique to the six billion or so other humans walking around on this planet. The small horizontal sensor found on the IBM and Fujitsu computers is different from the postage-stamp-size optical fingerprint readers of the past, in that it takes a series of sequential snapshots of a finger slid over the sensor. This "capacitive sensing" system does not store an actual image of a fingerprint on the computer. Instead, it reads the variations of electronic resistance on the surface of a living finger.

IBM stresses the word "living" in its literature on the fingerprint sensor technology. In a document titled "FAQ for the IBM fingerprint reader," question No. 19 addresses a concern only high-ranking government officials and James Bond types need worry over: "If my finger is cut off, can it be used to access my PC?"

The answer, IBM assures the counter-intelligence agents among us, is no. (The technology only senses electronic resistance from living finger cells, IBM promises, and furthermore, it takes only 15 minutes for the properties of a finger to decay to the point at which the sensor will no longer recognize it. Just in case you wanted to know.)
