baad mein, nirvaat tube ka istemaal kiya gaya. ye bahut tej the, lekin garmi utpann karte the aur filaameints ke jal jaane ke kaaran avishvasaneeya the. fainaaaut aam taur par paanch se saat the, jo tube ke vidyut se heeting dvaara seemit the. 1950 ke dashak mein, filaameint ke saath vishesh "computer tube" viksit kiye gaye jo silikaun ki tarah asthir tatvon ko nikaal dete the. ye kai hajaaron ghante tak chalte hain.
praudyogiki ke udaya ke saath, kuchh vyaktiyon ko RFID maanav pratyaaropan ke kaaran adhikaaron ki haani ka dar hai. vereechip ek RFID pratyaaropan par kaam kar raha hai jismein GPS traiking kshamata hogi.[84] ameriki sarkaar dvaara yeh takaneek na keval ek vyakti ke liye balki astitv mein maujood har bhautik vastu ki kisi bhi aur har samay bhaugolik avasthati jaanane ki anumati degi. jahaan ek or yeh takaneek laapata bachchon ya bhagodon ka pata lagaane mein sahaayata kar sakti hai, vaheen doosari or yeh sarkaaron ko RFID chip vaale kisi vastu ya vyakti par nazar rakhane ki anumati deta hai. iske alaava, ise saiddhaantik roop se kisi vyakti ki jaankaari ya sahamati ke bina kiya ja sakta hai; aur isi baat par vivaad hai.
kuchh dhoomrapaan karne vaalon ka tark hai ki dhoomrapaan ke avasaadak ka prabhaav unki nason ko shaant karta hai, aksar ekaagrata badhaane mein madad karta hai. haalaanki inpeeriyl college London ke anusaar, "nikoteen uttejak aur avasaad donon ka prabhaav dene lagta hai aur yeh sambhaavana hai ki yeh prabhaav kisi bhi samay upayogakarta ki manosthiti, paryaavaran aur upayog ki paristhitiyon dvaara nirdhaarit hota hai. adhyayan mein yeh bhi sujhaav diya gaya hai ki kam khuraak ka ek avasaadak prabhaav hai, jabki jyaada khuraak lene ka uttejak prabhaav hota hai.[67] tathaapi nikoteen ke upayog ke prabhaav aur nikoteen chhodne ke prabhaav ko alag karna asambhav hai.[krupaya uddharan jodein]
RFID praudyogiki ke kai upayogon mein se ek hai unka pustakaalayon mein prayog. is praudyogiki ne dheere-dheere pustakaalaya ki cheejon par (kitaabein, CD, DVD, aadi) paaramparik baarakod ki jagah lena shuroo kar diya hai. RFID taig mein pehchaan sambandhit jaankaari ho sakti hai jaise ek pustak ka sheershak ya saamagri prakaar, jiske tahat ek alag daataabes ki or ishaara karne ki aavashyakta naheen hogi (lekin yeh uttar America mein durlabh hai). yeh jaankaari ek RFID reedar dvaara padhi jaati hai, jo maanak baarakod reedar ko jo saamaanyat: ek pustakaalaya ki sanchalan mej par paaya jaata hai, pratisthaapit karta hai. pustakaalaya saamagri par paaya jaane wala RFID taig aamtaur par uttar America mein 50 mm X 50 mm aur Europe mein 50 mm x 75 mm ke naap ka hota hai. ise baarakod ki jagah ya usamein shaamil kiya ja sakta hai, jo staaf ko soochi prabandhan ka ek alag tareeka aur lene vaalon ko swayam seva pradaan karega. yeh ek suraksha upakaran ke roop mein bhi kaarya kar sakte hain aur paramparaagat vidyut chumbakeeya patti[28] ki jagah le sakte hain aur na keval kitaabein, balki sadasyata card mein bhi ek RFID taig lagaaya ja sakta hai.

January, 2005 mein, Wall-Mart ne apne sheersh 100 aapoortikrtaaon ke liye sabhi ladaan par RFID lebal lagaana jaroori kar diya. is aavashyakta ko poora karne ke liye, vikretaaon ne dabbon aur pailet par jismein Wall-Mart ke liye EPC taig ki aavashyakta thi, lebal lagaane ke liye RFID printar/inakodar ka upayog kiya. ye smart lebal, saamagri ke andar RFID inlej jad kar aur uske baad lebal ki satah par baar code aur dikhaai dene waali anya jaankaari mudrit kar ke nirmit kiye gaye hain.

praarambhik ekeekrut paripth ek aanandadaayak sanyog the. unhein paise bachaane ke liye nirmit naheen kiya gaya tha, balki vajan bachaane ke liye aur Apollo gaaideins computer ko ek antariksh yaan ko ek inarshial gaaideins system ko niyantrit karne ki anumati dene ke liye banaaya gaya tha. pehla ekeekrut paripth laujik gate ki keemat kareeb $50 thi (1960 dollar mein, jab ek engineer $10,000/varsh kamaata tha). sabhi ko aashcharyachakit karte hue, jab sarkit ka thok mein utpaadan hone laga to ve digital laujik nirmaan ki sabse sasti vidhi ban gaye. is praudyogiki mein sudhaar ne laagat mein sabhi baad ke sudhaaron ko prerit kiya.

rajistar hastaantaran laujik mein dviaadhaari sankhya flip flop ke samoohon mein sangraheet hain jise rajistar kaha jaata tha. pratyek rajistar ka aautaput taaron ka bandal hai jise ek "bas" kaha jaata hai jo anya aakalan ke liye us number ko paas rakhata hai. yeh aakalan keval sanyojan laujik ka ek bhaag hai. pratyek aakalan ke paas ek bas aautaput hota hai aur ye kai input rajistaron se juda ho sakta hai. kabhi-kabhi ek rajistar ke paas inke input par bahusanketak hota hai jisse yeh kai bason mein se kisi ek se number ko store kar sakta hai. vaikalpik roop se kai cheejon ke aautaput ko bafars ke maadhyam se joda ja sakta hai jo ek ko chhodkar sabhi upakaranon ke aautaput ko band kar sakta hai. input se pratyek rajistar ke naye data ko sveekaar karne par anukramik state machine niyantran karta hai.

mobile kanpyooting aur web praudyogikiyon ke saath milkar RFID, sangathanon ko apni sampatti ki pehchaan karne aur prabandhan karne ka tareeka pradaan karti hai. shuroo mein ekeekrut RFID reedar ke saath pramukh reetel kreg paitarasan, nauksavile, TN. mobile computer, mein shuroo kiya gaya jo ab upakaranon ka poora set pradaan kar sakte hain jo kaagaji kaarravaai ko samaapt kar sakta hai aur pehchaan aur upasthiti ka saboot de sakta hai. yeh tareeka shaareerik roop se deta pravishti ko samaapt karta hai.
dhoomrapaan karne vaale kai kishoraavastha mein ya aarambhik yuvaavastha ke dauraan shuroo karte hain. aam taur par praarambhik avastha mein dhoomrapaan sukhad anubhootiyaan pradaan karta hai, sakaaraatmak sudrudheekaran ke ek srot ke roop mein kaarya karta hai. ek vyakti mein kai varshon ke dhoomrapaan ke baad parihaar ke lakshan aur nakaaraatmak sudrudheekaran use jaari rakhane ka pramukh utprerak ban jaata hai.
poorvi uttar ameriki janajaatiyaan vyaapaar ke ek sahaj sveekaar taiyaar mad ke roop mein tambaakoo ke paauch ka badi maatra mein apne paas rakhate hain aur aksar pipe se dhoomrapaan karte hain, chaahe vah paribhaashit samaaroh ho jise pavitra maana jaata hai ya saude ko pakka karne ke liye[17] aur ve ise jeevan ke sabhi charanon sabhi avsaron par peete hain, yahaan tak ki bachapan mein bhi.[18][page needed] aisi maanyata hai ki tambaakoo is jagat ke nirmaata se mila ek ek upahaar tha aur tambaakoo ke kash se nikla dhuaan us vyakti vishesh ke vichaaron aur praarthanaaon ko svarg tak le ja paane mein saksham hai.[19]
baithakon aur sammelanon mein bhi upasthiti baij mein RFID praudyogiki laagoo ki ja rahi hai taaki sammelanon mein logon ko track kiya ja sake. isse jo aankada upalabdh hota hai usase pata chalta hai ki logon ne din ke samay kis kamre mein pravesh kiya aur baahar gaye.[51] yeh data aayojakon ko dikhaane ke liye upalabdh hota hai taaki sammelan ki saamagri aur dijaain mein sudhaar karne mein unki madad ki ja sake. pradarshaniyon mein pradarshakon ke liye netrutv bahaali prakriya mein sudhaar karne ke liye bhi RFID ka upayog kiya ja raha hai.
raksha ki ek dviteeya shreni, taig kloning ko rokane ke liye kriptograafi ka upayog karti hai. kuchh taig ek prakaar ke "roling code" yojana ka upayog karte hain, jismein taig pahachaanakarta jaankaari pratyek scan ke baad parivrtit ho jaati hai, is tarah dekhi gayi pratikriyaaon ki upayogita ko kam kar deti hai. adhik parishkrut upakaran chunauti-pratikriya pramaaneekaran mein sanlagn hote hain jahaan taig, reedar ke saath soochana ka aadaan pradaan karta hai. in protokaul mein, taig aur reedar ke beech asurakshit sanchaar channel par gupt taig jaankaari naheen bheji jaati hai. balki, reedar taig ke liye ek chunauti jaari karta hai, jo ek parinaam ke saath javaab deta hai jiski ganana kuchh gupt moolya ke saath bandhe kriptograafik sarkit ka upayog karte hue ki jaati hai. aise protokaul, samamit ya saarvajanik kunji kriptograafi par aadhaarit ho sakta hai. koot roop se saksham taig ki aamtaur par keemat naatakeeya roop se uchch hoti hai aur ise saral samakaksh se adhik bijli ki aavashyakta hoti hai aur parinaamasvaroop in taig ki tainaati adhik seemit hai. is laagat/vidyut bandhan ne kuchh nirmaataaon ko kaafi kamjor ya svaamitv waali enkripshan yojanaaon ka upayog karke kootlekhit taig lagaane mein prerit kiya, jo parishkrut hamle ko aavashyak roop se naheen rokate. udaaharan ke liye, eksaun-mobil speedapaas, Texas instroomeints dvaara nirmit ek kootalekh-saksham taig ka upayog karta hai, jise digital signechar traansapondar (DST) kehte hain, jismein kam laagat ke liye ek chunauti-pratikriya protokaul karne ke liye ek kamjor, svaamitv enkripshan yojana shaamil hai.
electronic cigarette tambaakoo ke dhoomrapaan ka ek vaikalpik tareeka hai, haalaanki ismein tambaakoo ka sevan ekdam naheen kiya jaata. yeh ek baitari se chalne wala upakaran hai jo vaashpeekrut propilen glaaikol (propylene glycol)/ nikoteen ghol se nikoteen ki khuraak saans se andar bhejata hai. kaanooni aur saarvajanik svaasthya ki jaanch ke kai maamale vartamaan mein kai deshon mein lambit pade hain, jo iske kaaran apekshaakrut haal mein ubhare hain.
pashu taiging ke liye dijaain kiye gaye pratyaaropit kiye jaane vaale RFID chip, ab insaanon mein istemaal kiye ja rahe hain. RFID pratyaaropan ke saath ek aaranbhik prayog, saaibaranetiks ke british professor kevin vaaravik dvaara kiya gaya jinhonne 1998 mein apne haath mein ek chip pratyaaropit kiya. 2004 mein kaunaraad ches ne Barcelona aur rautaradaim mein apne naait club mein apne VIP graahakon ki pehchaan ke liye jo iska prayog peya ke bhugataan ke liye karte the, pratyaaropit chips ki peshakash ki[42].

aam taur par teen prakaar ke RFID taig hote hain: sakriya RFID taig, jismein ek baitari hoti hai aur ye sanketon ko svatantr roop se sanchaarit kar sakte hain, nishkriya RFID taig, jismein baitari naheen hoti aur sanket sancharan prerit karne ke liye ek baahari srot ki jaroorat hoti hai aur baitari samarthit nishkriya (BAP) jise jaagane ke liye baahari srot ki aavashyakta hai lekin ismein mahatvapoorn uchch fauravard link kshamata hai jo atyadhik pathan seema pradaan karta hai.
apratyaksh dhoomrapaan tambaakoo ke dhuen ka anaichhik sevan hai. second hand dhoomrapaan (SHS) vah khapat hai jahaan sulagane ka sira maujood hota, paryaavaran tambaakoo dhoomrapaan (ETS) ya thard hand dhoomrapaan vah dhoomrapaan hai jiska upabhog jalne vaale sire ke baad bhi hota rahata hai. iske nakaaraatmak prabhaav ke kaaran upabhog ke is svaroop ne tambaakoo utpaadon ke viniyman mein ek keindreeya bhoomika nibhaai.
RFID praudyogiki ke upayog ne kaafi vivaad ko janm diya aur yahaan tak ki upabhokta gopaneeyata pairokaaron dvaara utpaad bahishkaar bhi hua. CASPIAN (kanjyoomar ageinst suparamaarket praaivesi invejn end nambaring) ki sah-sansthaapak Cathrine albrekt aur lij maikintaayar is praudyogiki ki do pramukh aalochak hain jo RFID taig ka ullekh "spaaichips" ke roop mein karti hain. RFID sambandhit do mukhya gopaneeyata chintaaen hain:
1980 ke dashak mein mile vaigyaanik pramaan ke anusaar tambaakoo companiyaan ne daava kiya hai ki laaparavaahi baratne ka kaaran svaasthya par padne vaale pratikool prabhaav se pehle unka anajaan hona tha ya paryaapt vishvasaneeyata ka abhaav tha. svaasthya adhikaariyon ne 1998 tak in daavon ka saath diya jiske baad unhonne apni sthiti ulat di. tambaakoo pradhaan niptaan samjhauta (the tobaiko master saitalameint egreemeint) mool roop se chaar sabse badi tambaakoo companiyon aur 46 raajyon ke ameriki etorni general ke beech hua. tambaakoo ke kuchh khaas prakaar ke vijnyaaapanon par pratibandh laga diya gaya aur svaasthya muaavaje ke taur par bhugataan ko aavashyak kar diya gaya, jo baad mein sanyukt raajya America ke itihaas mein sabse bade naagrik niptaan ke roop saamane aaya.[36]

kredit card companiyaan ab kisi bhi mobile phone se gair-sampark bhugataan card jodne ke liye bhugataan samaadhaan talaash rahi hain. ek vaahak samaadhaan jo is udyog ki jaroorat ko poora kare ab upalabdh hai. 3mm se kam mota, yeh up-card 2 varshon tak apne paryaavaran ko jhel sakega aur ek baar daale jaane ke baad yeh tatvon se rakshit aur vaahak mein surakshit rahega.[10]


tambaakoo mein sakriya tatv, vishesh roop se cigarette mein patton ko jalaakar aur vaashpeekrut gas ko saans se kheenchakar praapt kiya jaata hai. yeh jald aur prabhaavi dhang se padaarthon ko khoon mein avashoshit kar fefadon mein koshikaaon ke jariye pahunchaaya jaata hai. fefadon mein lagbhag 300 million rakt koshikaaen hoti hai, jiske satah ka kshetrafal 70 m2 (ek tennis court ke aakaar ke baraabar) hota hai. yeh vidhi vifal hai kyonki poora dhuaan saans se naheen kheencha jaata hai aur sakriya padaarthon mein se kuchh maatra jalaaye jaane ki prakriya ke dauraan vaashpeekaran mein nasht ho jaati hai.[9] pipe aur sigaar ka dhuaan uchch kshaarayukt hone ke kaaran saans se naheen kheencha jaata jo shvaasanali aur fefadon ko haani pahuncha sakte hain. tathaapi, cigarette (pH 5.3) ke dhuen ki tulana mein iske uchch kshaarayukt (pH 8.5) hone ke kaaran sangathit nikoteen aur adhik aasaani se munh mein shleshm jhilli ke maadhyam se avashoshit kar leta hai.[45] sigaar aur pipe se nikoteen avashoshan baharahaal cigarette ke dhuen se bahut kam hota hai.[46]
