Finger print readers - bad quality often reported with older users

Posted on 2009-02-16
Last Modified: 2013-11-17

I like to supply laptops with finger print readers and software such as that prodced by digital persona which has website logon and is graet.

However, older users more often seem to have a great deal of diffictulty in my experiance and I was wondering if anyone had some good advice or techniques on how to get better results for these users.
It would be nice if they had 100% recognition rather then the about 5% recognition that they currently seem to get.

Any tips apprecaited.

    Well.... Not wanting to oversimplify or affront anyone, I can give you my opinion that older users (as in, say, 75+), have a tendency towards crinkly, worn, dry, scarred and generally harder-to-read fingertips than younger people. Why do you want older users to use the fingerprint reader system? Old-fashioned passwords seem to give you higher functionality and comparable security.

    Well in this they are 50+ year old business users (so not that old) who are a bit slow with computers but have embraced them and once were demonstrated the finger print reader wanted it.
    I heard about the worn fingerprints but could not find a tactful way of raising the matter.

    Accepted Solution

    I see. I'm 50+ myself and do a lot of mechanical work, so have lots of little scratches and stuff on my fingertips. The only thing that comes readily to mind, using myself as template, is to advocate the use of a left hand finger for the right-handed and vice versa and to actively choose a "well-preserved" finger (that should be something that can be explained in a "technical" vein, without being tactless); e.g. left little finger should be one fairly well protected in a right-handed person.

    The use of skin lotions for hands might be encouraged, so as to prevent excessively dry skin that may develop cracks that confuse the fingerprint readers. I'm not trying to be funny, really... New technology demands new sacrifices :)
