a) Two other physical characteristics are palm print and iris.
b) We can authenticate an identity in three ways first by something a user knows (password) second something a user has (smart card) and third something a user is (face, fingerprints). When a person puts any of these things in a system and wants to be authenticated the biometric features are re-scanned then they are matched with information in database and then it is either authenticated or rejected.
c) It is better to have biometric options for payments at retail stores than to have a signature for a credit card becuase people put their signature on almost anything now. A lot of people lose their credit cards and anyone can just find a persons signature and practice forging it. But if a retail store had people give their fingerprints or something than that would NOT be easy to seal. Fingerprint authentication has a 99% accuaracy rate because the only way for someone to be able to steal your identity is by getting close to you and you will surely notice then or copy it from the machine but then they might get caught or more than one persons identity mixed in so that would probably not work.
d) Some concerns that people might have if biometric authentication became widespread are one identity theft if images of fingerprints are stolen than criminals can easliy use then to steal identities.Second physical concerns for example if someones iris is exposed to a lot of technology because stores want authentication that could easily lead to eye disease. Third is privacy personal information could be sold to other organizations without the persons knowlege or consent. Fourth is integrity because since their is human input into the system mistakes could happen and the system might have some problems in it There are many more concerns but these are just a few.
