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.
radio-aavrutti pehchaan (angreji: Radio-frequency identification) ek vastu ka upayog hai (aamtaur par ek RFID taig ke roop mein sandarbhit) jise ek utpaad, pashu, ya vyakti mein radio tarangon ke istemaal se pehchaan karne aur traiking ke uddeshya se lagaaya ya daala jaata hai. kuchh taig ko kai meter door se aur paathak ki drushti rekha ke paar se padha ja sakta hai.

adviteeya pehchaan, RFID taig ke liye ek anivaarya aavashyakta hai, number yojana ki vishesh pasand ke baavajood. RFID taig deta kshamata itni badi hogi ki har vyaktigat taig mein ek adviteeya code hoga, jabki vartamaan baar code, kisi vishesh utpaad ke liye ek hi prakaar ke code ke liye seemit hain. RFID taig ki vishishtata ka matlab hai ki kisi utpaad ko ek sthaan se doosare sthaan par jaate samay track kiya ja sakega, jo antat: upabhokta ke haathon mein samaapt hoga. isse chori aur utpaad nuksaan ke anya roopon se nipatne mein madad milegi. utpaadon ka anurekhan ek mahatvapoorn visheshata hai jise taig ki ek anoothi pehchaan aur vastu ki kram sankhya vaale RFID taig se achhi tarah se samarthan milta hai. isse companiyon ko gunavatta ki kami aur parinaamasvaroop smruti abhiyaan se nipatne mein madad milegi aur saath hi bikri ke baad upabhoktaaon ki traiking aur rooparekha ke baare mein chinta bhi badhegi.
paanv ki daud mein, dhaavak nishkriya taig pahanate hain jo track ke donon chhoron ya track ke aar-paar bichhe Matt par rakhe enteena dvaara padha jaata hai. nyoon ya uchch freekveinsi antim peedhi taig ke bajaay UHF aadhaarit taig, vishesh roop se design kiye gaye entena ke dvaara sateek reeding pradaan karte hain. rash truti, laip kaaunt trutiyaan aur durghatanaaon se bacha ja sakta hai choonki bina ek batch mod mein rahe koi bhi kabhi bhi shuroo aur khatm kar sakta hai.
1945 mein lion theremin ne soviyt sangh ke liye ek jaasoosi upakaran ka aavishkaar kiya jo shravya jaankaari ke saath ghatna radio tarangon ko pun: sanchaarit karta tha. dhvani tarangein ek daayafraam ko hilaati thi jo rejonetar ke aakaar ko thoda badal deti thi, jo pratibinbit radio aavrutti ko modyulet kar deti thi. yadyapi yeh upakaran ek gupt shravya upakaran tha, na ki ek pehchaan taig, ise RFID praudyogiki ka ek poorvavarti maana jaata hai, kyonki yeh bhi vaise hi nishkriya tha, jo ek baahya srot se vidyutachumbakeeya tarangon dvaara shaktishaali aur sakriya ho jaata tha.[1]

Singapore mein, saarvajanik parivhan ki bason aur trainon mein nishkriya RFID ko laagoo kiya gaya hai jise EZ-Link card ke roop mein jaana jaata hai. bheed bhare shahar ke aatanrik kshetron mein yaataayaat ko char tol dvaara niyantrit kiya jaata hai jise stord vailyoo card (kaishakaard ke roop mein gyaat) ke upayog ko ek sakriya taiging pranaali ke saath upayog dvaara laagoo kiya jaata hai.
donon ke paas hi aankade seemit hain. rog niyantran aur rokathaam kendra (the seintars for dijeej control end prijrveshan) ne 2002 mein prakaashit apne anusandhaan mein daava kiya hai ki sanyukt raajya America mein beche gaye ek packet cigarette par chikitsa dekhbhaal aur utpaadak hraas par 7 dollar se adhik ki laagat aati hai.[70] laagat aur adhik ho sakti hai jabki ek anya adhyayan mein use prati packet par $ 41 ki laagat bataayi hai, jinmein se jyaadaatar vyaktigat aur usaki/ uske parivaar ko vahan karna padta hai.[71] is tarah se ek anya aur adhyayan ke lekhak doosaron ke liye bahut kam laagat bataate hue kehte hain: "sankhya ke kam hone ka kaaran niji peinshan, saamaajik suraksha aur chikitsa hai- kharch ki ganana mein sabse bada kaarak samaaj hai- dhoomrapaan vaastav mein paise bachaata hai. dhoomrapaan karne vaale kam umr mein mar jaate hain aur ve vah dhan naheen uthaate jo un pranaaliyon se unhein bhugataan kiye jaate.[71]
vipanak (adhikatar) yah jaanakar prasann honge ki sampoorn maanav-vishisht kaaryon ke svachaalan ko saksham karane vaalee unnat takaneek ke saath 2017 mein svachaalan ek bada aadhaar ban jaega. hamaare paas kuchh varshon ke lie prachalan mein robot patrakaar the, aur mujhe ummeed hai ki ve adhik vyaavahaarik prakaar ke lekhon mein ek aur chhalaang lagaane se pahale lambe samay tak nahin rahenge. aisa hone kee sambhaavana hai ki ham kaee prakaar kee shvet-kolar prakaar kee naukariyon mein utpaadakata badhana shuroo kar denge- aur ham kuchh naukariyon ko pooree tarah se gaayab hone se dekhana shuroo karenge. jab otomeshan masheen seekhane ke saath joda jaata hai, to sab kuchh bhee tez ho sakata hai, isalie 2017 mein vaastav mein ek meel ka patthar varsh hone kee sambhaavana hai.
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.

haai-freekveinsi RFID ya HFID/HighFID taig pustakaalaya ki pustakon ya kitaabon ki dukaan ki traiking, gahanon ki traiking, pailet traiking, abhigm niyantran nirmaan, airline saamaan traiking aur paridhaan aur davaaon ki traiking. haai-freekveinsi taig, vyaapak roop se pehchaan baij mein prayukt hote hain jinhonne pehle ke maignetik-straaip card ka sthaan liya. dhaarak ko pramaanit karne ke liye in baij ko reedar se ek nishchit doori ke bheetar rakhana hota hai. American express blue kredit card mein ab ek HighFID taig shaamil hai. fravari 2008 mein, ameeraat airline ne London aur dubai havaai addon par RFID saamaan traiking ka pareekshan shuroo kiya.
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.
purushon mein mahilaaon ki tulana mein dhoomrapaan ki lat paanch guna adhik hoti hain,[13] haalaanki chhote aayu varg mein is laingik antar mein giraavat aati hai.[14][15] viksit deshon mein purushon mein dhoomrapaan apne charam par pahunch chuka hai aur usamein giraavat aani shuroo ho gayi hai haalaanki mahilaaon ke maamale mein vruddhi barkaraar hai.[53]
san 2000 mein 1.22 log dhoomrapaan karte the. prachalan mein parivartan ka koi anumaan na lagaate hue yeh bhavishyavaani ki gayi hai ki 2010 mein 1.45 billion log aur 2025 mein 1.5 se 1.9 billion log dhoomrapaan kareinge. maan lein ki prasaar ek saal mein 1% kam hota hai aur aay mein 2% ki maamooli vruddhi hoti hai to dhoomrapaan karne vaalon ki sankhya 2010 aur 2025 mein anumaanit 1.3 billion hogi.[13]
