poore Europe mein aur vishesh roop se peris mein (pranaali RATP dvaara 1995 mein shuroo ki gayi), lion, bordo, grenobal, nainsi aur maarsile France mein, poore purtagaali raajamaarg vyavastha mein aur kai purtagaali saarvajanik car park mein, Milan, turin, Italy mein nepals aur floreins aur Belgium mein brasels, kailipso antararaashtreeya maanak ke anuroop RFID paas ka saarvajanik parivhan pranaali ke liye upayog kiya jaata hai. unka upayog ab Canada (mauntriyl), maiksiko, isaraail, Columbia mein bogota aur parera, naarve mein stavaangar, laksamabarg, aadi mein bhi kiya jaata hai.
jin deshon mein ek saarvajanik svaasthya pranaali hai, vahaan dhoomrapaan karne vaale beemaar logon ki samaajik chikitsa dekhbhaal ki laagat karon mein vruddhi ke maadhyam se vahan ki jaati hai. is morche par do tark maujood hain, "dhoomrapaan samarthakon" ka tark hai ki bhaari dhoomrapaan karne vaale aam taur par lamba jeevan naheen jeete jisse budhaape ko prabhaavit karne waali kharcheeli aur puraani beemaari naheen hoti aur yeh samaaj mein svaasthya seva ke bojh ko kam karta hai. "dhoomrapaan virodhi" tark ke anusaar svaasthya chikitsa ka bojh badhta hai kyonki dhoomrapaan karne vaalon ki saamaanya aabaadi ki tulana mein kam umr mein lambi beemaari dar adhik hai.
usi samay, nae ekeekrut paripth (ICs) eliyn, impinj aur NXP (poorv mein Philips) dvaara shuroo kiye gaye jisne behtar pradarshan dikhaaya aur IT parisanpatti nigraani anuprayog mein visfot hua. aaj ki taareekh mein isko bruhat paimaane par apnaane vaale bank of America aur vels faarago prateet hote hain - pratyek ki ek darjan se adhik deta kendron mein 100,000 se adhik parisanpatti hai.[16]
cigarette se utpann ek paroksh saarvajanik svaasthya samasya durghatanaavash lagne waali aag hai, jo aamtaur par sharaab ke sevan ke saath judi hai. cigarette ki kai dijaainein prastaavit hain, kuchh swayam tambaakoo companiyon, jo cigarette ke ek ya do minute tak istemaal na kiye jaane par bujhaane se judi hain, taaki aag lagne ka jokhim kam ho jaaye. ameriki tambaakoo companiyon ke alaava kuchh ne is vichaar ka virodh kiya hai, jabki anya ne ise apnaaya hai. aaraje renolds 1983 mein in sigreton ke prototaaip banaane ke netrutvakarta the[99] aur ameriki baajaar ke sabhi sigreton ko 2010 tak aag se surakshit bana diya jaayega.[100] Phillip mauris iske sakriya samarthan mein naheen hai.[101] desh ki teesari sabse badi tambaakoo company lorillaard (Lorillard) asamanjas mein lagti hai.[101]
lekha-pareekshak aksar kaate gaye chekon ke samarthan mein anumodit beejakon, vyaya riporton aur anya samarthak pralekhanon ki maujoodagi par dhyaan keindrit karte hain. aapoortikrta se pushtikran ya bayaan ka hona, khaate ke astitv ka samuchit pramaan hai. yeh asaamaanya naheen hai ki lekha-pareeksha ke chaaloo hone tak, inmein se kuchh pralekhan kho jaaen ya glat faailon mein rakhe jaaen. aisi sthitiyon mein lekha-pareekshak namoone ke aakaar ko badhaane ka faisala kar sakte hain.
agar system vaanchhit degree ki vishvastata ke pratinidhitv karne ke liye paryaapt digital deta ka bhandaaran karta hai to parimaaneekaran truti ko kam kiya ja sakta hai. ek nirdhaarit enaalaug sanket ko theek-theek prastut karne ke liye kitni digital data ki aavashyakta hoti hai usaki jaankaari naaikvist-shaannon namoona prameya ek mahatvapoorn nirdesh pradaan karta hai.

saare pareekshan ke baad, deta bits jagah par hain, dijaain ko "saamaanya mod" ke liye reekanfigr kiya jaata hai aur ek ya ek se adhik klauk pals ko laagoo kiya jaata hain, taaki dosh ka pata lag sake (jaise stak-ait lo ya stak-ait haai) aur pareekshan ke parinaam ka pragrahan scan shift rajistar mein flip-flop mein aur/ya leches mein kiya jaata hai. ant mein, pareekshan ke parinaam ko block seema mein sthaanaantarit kar diya jaata hai aur poorvaanumaan "gud machine" nateeje ke prati tulana ki jaati 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.
