digital bhangasheelata ko ek digital pranaali ke roopaankan dvaara majabooti ke liye kam kiya ja sakta hai. udaaharan ke liye ek pairiti bit ya anya truti prabandhan paddhati ko signal path mein daala ja sakta hai. yeh paddhati system ko, truti ka pata lagaane mein madad karti hai aur ya to trutiyon ko sahi karti hai ya fir kam se kam deta ki ek nai pratilipi ke liye poochhati hai. ek state machine mein state traanjishn laujik ka aprayukt state ko pakadne aur ek reeset anukram trigr ya anya niyamit truti vasooli ke liye design kiya ja sakta hai.
passport ko adhik surakshit banaane ke prayaas mein kai deshon ne passport mein RFID laagoo kiya hai. baharahaal, Britain ke chips par enkripshan ko 48 ghante ke andar tod diya gaya tha.[66] us ghatna ke baad se aur adhik prayaas ne shodhakartaaon ko, jab passport ko uske maalik ke paas bheja ja raha ho us vakt passport deta ko klon karne ki anumati di. jahaan ek aparaadhi ko chupake se lifaafe ko kholana aur fir band karne ki jaroorat thi, ab yeh pata lage bina kiya ja sakta hai, jisse passport pranaali mein kuchh asuraksha badh gayi hai.[67]
kai adhyayanon ne yeh sthaapana ki hai ki cigarette ki bikri aur dhoomrapaan ke upayog ke samay sambandhi dhaanche alag hain. udaaharan ke liye, sanyukt raajya America mein cigarette ki bikri ka dhaancha kaafi had tak mausam se juda hua hai, garmi ke maheene mein iski bikri kaafi badh jaati hai, jabki sardiyon mein iski khapat kam ho jaati hai.[68]
saan Diego, California, metropolitan traanjit system (MTS), north County traanjit distrikt (NCTD) aur the sain Diego asosiyeshan of gavarmeint (SANDAG) ek ri-raaitebal RFID smart card ka upayog karti hai jise sthaaneeya taur par kampaas card ke roop mein nirdisht kiya jaata hai aur bason aur railgaadiyon ki yaatra aasaan banaane ke liye dainik, saaptaahik ya maasik paas ya nakad moolya ke roop mein upayog kiya ja sakta hai.
lekin, January 2009 mein saims club ne paalan na karne par lagne vaale jurmaane ko kaafi kam kar diya, jise usane prati pailet $2 se ghataakar sirf 12 seint prati pailet kar diya. Wall-Mart ka anumaan hai ki saims ke liye khud taiging karne par prati pailet 12 seint ka kharcha aaega. saims ne yeh bhi ghoshana ki ki pailet-stareeya taiging ko 2010 mein poori shrrunkhala bhar mein shuroo kiye jaane ki ummeed hai, jabki vyaktigat vastu par taiging ki samay seema "vichaaraadheen" hai.
kai deshon ne tambaakoo karaadhaan ke kuchh tareeke laagoo kiye hain. 1997 mein Denmark mein cigarette ke pratyek packet par 4.02 dollar ka uchchatam kar bojh tha. taaivaan mein pratyek packet par keval 0.62 dollar ka kar bojh tha. vartamaan mein sanyukt raajya America mein sigreton par moolya aur utpaad kar ka ausat kai anya audyogik deshon se neeche hai.[86]
yaantrik tark aksar aisi vaashing machine mein un logon ke roop mein saste niyantrakon mein prayog kiya jaata hai. mashahoor roop se, Charles baibej dvaara pehla computer design ko yaantrik laujik ke prayog ke liye dijaain kiya gaya tha. yaantrik laujik ko, bahut chhote computer mein bhi istemaal kiya ja sakta hai jise naino takaneek dvaara banaaya ja sakta hai.
kuchh pranaaliyon mein yadi digital deta ka ek bhaag lupt ho jaae ya galat tareeke se vyavahrut hon, to sambandhit deta ke vishaal khandon ka arth poori tarah se badal sakta hai. kyonki kleef ifekt ke kaaran, upayogakartaaon ke liye bataana mushkil hai ki koi vishisht system vifalta ke kagaar par sahi tha ya fir vah asafal hone se pehle bahut adhik shor ko sahan kar sakta hai ya naheen.
