Figure 3.8 Identity.cards.are.often.read.by.proximity.card.readers.to.
allow.access..These.create.records.
as.special.discounts..Or.in.some.cases,.it.may.be.something.
that.was.developed.by.someone.in.the.organization.to.simply.
keep.track.of.these.authentications.. In.any.case,.when.you.
swipe.your.card.at.the.door,.or.present.it.to.the.clerk,.elec-
tronic.data.are.created.that.tell.the.date.and.time.of.use.
There.are.many.reasons.you.or.someone.else.might.want.
to.access.that.data..It.could.be.needed.to.answer.a.question.
regarding.litigation,.or.to.prove.you.were.somewhere.when.
you.said.you.were,.or.perhaps.to.show.that.someone.wasn't.
where.he.or.she.purports.to.have.been..In.all.cases,.you.will.
need.to.know.where.the.data.reside,.who.has.control.over.the.
data,.and.what.will.be.required.to.recover,.examine,.preserve,.
and.organize.the.data.for.whatever.need.you.have.
For. example,. consider. the. case. where. a. manager. feels.
that. one. of. her. employees. isn't. getting. his. work. done. efi-
ciently..As.far.as.she.can.tell,.the.employee.is.showing.up.for.
work.on.time.in.the.mornings.because.she.sees.him.walk.by.
her.desk.on.his.way.to.his.cube..And.he.seems.to.be.leaving.
work.when.he.is.supposed.to.because,.again,.he.waves.to.her.
as.he.leaves.the.ofice..So,.unable.to.understand.what.might.
be.going.on.to.keep.him.from.getting.his.work.done,.one.of.
the.things.she.does.is.to.ask.the.facilities.manager.for.a.report.
from.the.proximity.readers.on.their.loor.
