1612 mein jemsataaun ke avasthaapan ke chhah saal baad John raalf pehle adhivaasi hain jinhonne tambaakoo ki ek nakadi fasal ke roop mein safalataapoorvak kheti ki. tambaakoo ki maang mein teji se vruddhi hui, use "bhoora sona" kaha gaya, kyonki usane sone ke abhiyaan mein vifal varjeeniya ko share company mein punarjeevit kar diya.[21] puraani duniya ki maangon ko poora karne ke liye tambaakoo ki paidaavaar lagaataar ki gayi jiske parinaamasvaroop jameen ki urvara shakti sheegra hi kam ho gayi. isne pashchim ko ek agyaat mahaadveep mein basane ke liye prerak ka kaarya kiya aur isi tarah tambaakoo utpaadan ka ek vistaar hua.[22] bekan vidroh ke pehle tak anubandhit daasata hi praathamik shram bal ka aadhaar thi jiske kaaran das pratha par dhyaan kendrit hua.[23] yeh pravrutti ameriki kraanti ke baad kam hui aur daasapratha laabhaheen maani gayi. haalaanki yeh pratha 1794 mein punarjeevit ho gayi jab kapaas ki charkhi ka aavishkaar hua.[24][page needed]
sanyukt raajya America mein, Chicago traanjit praadhikran ne poori pranaali mein 2002 ke baad se rel bhugataanon ke liye Chicago card aur Chicago card plas ki peshakash ki aur 2005 ke baad se bas bhugataanon ke liye. MBTA ne RFID saksham chaarleekaard ko 2006 mein Boston ke sampoorn metro, streetakaar aur bas pranaali mein laagoo kiya aur dashakon puraane tokan aadhaarit kiraaya sangrah pranaali ko pratisthaapit kiya.

POS store chekaaaut ke liye bhi RFID upayog ka prastaav kiya gaya hai jo khajaanchi ko ek svachaalit tantr se pratisthaapit karega jise kisi baarakod skaining ki jaroorat naheen hoti hai. poorv mein taig ki uchch laagat aur us vakt maujood POS proses praudyogiki ki vajah se yeh sambhav naheen tha. haalaanki, industry stainadard, ohiyo mein ek vastr ki dukaan aur rikaurding studio ne safalataapoorvak ek POS prakriya ko implemented kiya hai jo sampoorn lenaden ko apekshaakrut teji se karne ki anumati deti hai.
suraksha visheshagyon ne pehchaan ki chori ke jokhim ke kaaran logon ke satyaapan ke liye RFID ka upayog karne ke khilaaf chetaavani di hai. udaaharan ke liye ek madhya vyakti hamla ek hamlaavar ko vaastavik samay mein ek vyakti ki pehchaan chori karne mein saksham banaaega. RFID ke sansaadhan kami ke kaaran hamlon ke aise model ke khilaaf suraksha vastut: asambhav hai, kyonki ismein jatil doori-bandhan protokaul ki aavashyakta hoti hai.[43][44][45][46]
prativedan ke liye engineer digital system ke prakaaron par vichaar karte hain. adhikaansh digital system "sanyojan system" aur "anukramik system" mein vibhaajit ho jaate hain. sanyojan pranaali mein hamesha jo input diya jaata hai vahi aautaput vah deta hai. yeh mool roop se laujik prakriya ke set ka pratinidhitv karta hai aur jiski charcha pehle hi ki ja chuki hai.
isi prakaar ki samaan praudyogiki, jaise United Kingdom mein 1915 mein aavishkaar ki gayi IFF traansapondar, ka dviteeya vishv yuddh mein mitr raashtron dvaara vimaanon ki dost ya dushman ke roop mein pehchaan karne ke liye niyamit roop se istemaal kiya gaya. abhi bhi traansapondar ka, atyadhik shaktishaali vimaan dvaara aaj bhi prayog kiya jaata hai. RFID ki padtaal karta ek anya kaarya, 1948 ka Harry staukaman ka mahatvapoorn pepar hai, jiska sheershak tha "kamyunikeshan baai meens of riflekted power" (IRE ki kaaryavaahi, pp 1196–1204, October 1948). staukaman ne bhavishyavaani ki ki "... riflekted-power sanchaar mein shesh buniyaadi samasyaaon ko hal karne aur upayogi anuprayogon ke kshetr ka pata lagaane se pehle kaafi anusandhaan aur vikaas ka kaam kiya jaana hai."
gair electronic digital tantr nirmaan sambhav hai. siddhaant roop mein, asatat state ka pratinidhitv aur laujik kaaryon ka pratinidhitv karne mein saksham kisi bhi takaneek ka istemaal yaantrik laujik banaane ke liye kiya ja sakta hai. MIT ke chhaatron, erleen gi, Edward haardabek, daini hilis (the kanekshan machine ke sah-lekhak), maargaret minsaki aur bairi aur Brian silvaraman bhaai, ne tinkar khilaune, string, ek int aur ek teevr peinsil se do computer ka nirmaan kiya.[3] tinkaratauya computer, Boston vigyaan sangrahaalaya mein hai.

tambaakoo dhoomrapaan ek aisa abhyaas hai jismein tambaakoo ko jalaaya jaata hai aur usaka dhuaan ya to chakha jaata hai ya fir use saans mein kheencha jaata hai. iska chalan 5000-3000 E.poo.ke praarambhik kaal mein shuroo hua.[1] kai sabhyataaon mein dhaarmik anushthaanon ke dauraan ise sugandh ke taur par jalaaya gaya, jise baad mein aanand praapt karne ke liye ya fir ek saamaajik upakaran ke roop mein apnaaya gaya.[2] puraani duniya mein tambaakoo 1500 ke dashak ke antim daur mein prachalit hua jahaan isne saajha vyaapaarik maarg ka anusaran kiya. haalaanki yeh padaarth aksar aalochna ka shikaar banta raha hai, lekin iske baavajood vah lokapriya ho gaya.[3] jarman vaigyaaniko ne aupachaarik roop se der se 1920 ke dashak ke ant mein dhoomrapaan aur fefade ke Cancer ke beech ke sambandhon ki pehchaan ki jisse aadhunik itihaas mein pehle dhoomrapaan virodhi abhiyaan ki shuruaat hui. aandolan tathaapi dviteeya vishv yuddh ke dauraan dushmanon ki seema mein pahunchane mein naakaam raha aur uske baad jald hi alokapriya ho gaya.[4] 1950 mein svaasthya adhikaariyon ne fir se dhoomrapaan aur Cancer ke beech ke sambandh par charcha shuroo ki.[5] vaigyaanik pramaan 1980 ke dashak mein praapt hue, jisne is abhyaas ke khilaaf raajaneetik kaarravaai par jor diya. 1965 se viksit deshon mein khapat ya to ksheen hui ya fir usamein giraavat aayi.[6] haalaanki, vikaasasheel duniya mein badhat jaari hai.[7]
1995 se 1970 ke beech gareeb vikaasasheel deshon mein prati vyakti cigarette ki khapat mein 67 pratishat ki vruddhi hui hai, jabki usamein ameer viksit duniya mein 10 pratishat giraavat aayi hai. dhoomrapaan karne vaalon mein se assi pratishat ab kam viksit deshon mein rahate hain. 2030 tak vishv svaasthya sangathan (WHO) ki bhavishyavaani hai ki 10 million logon ki maut prativrsh dhoomrapaan se sambandhit beemaariyon se hogi jo duniya bhar mein maut ka ek sabse bada kaaran hoga, mahilaaon mein iski sabse badi vruddhi hogi. WHO ki bhavishyavaani hai ki 20 veen sadi mein dhoomrapaan se hui mauton ki daron mein 21 veen sadi mein das guna vruddhi hogi. ("Washington"(Washingtonian) patrika, December 2007).
