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.
parirkshan, fir ek prayukt ki ja rahi freekveinsi ka kaarya hai. lo frikvesnsi LowFID taig, jaise jo manushya aur paalatoo jaanvaron ke liye pratyaaropan yogya upakaranon mein istemaal hote hain, parirkshan ke prati apekshaakrut pratirodhi hain, haalaanki mote dhaatu ki panni adhikaansh pathan ko rokegi. haai freekveinsi HighFID taig (13.56 MHz - smart card aur abhigm baij) parirkshan ke prati samvedansheel hain aur jab ye kisi dhaatu ki satah ke kuchh seinteemeetar ke andar hote hain to inhein padhna mushkil hota hai. UHF Ultra-HighFID taig (pailet aur dibbe) ko padhna kathin hai jab unhein kisi dhaatu ki satah ke kuchh meeleemeetar ke bheetar rakha jaae, haalaanki unki pathan seema vaastav mein badh jaati hai jab unhein kisi dhaatu se 2–4 cm par rakha jaata hai aur iska kaaran hai taig par pratibinbit tarang aur insideint tarang ka sakaaraatmak sudrudheekaran. UHFID taig ko sthaitik-virodhi plastic bag ke andar rakh kar adhikaansh pathan se safalataapoorvak parirkshit kiya ja sakta hai.[sandigdh – charcha karein]

ek baar koi dijaain maujood hai aur satyaapit aur pareekshan yogya hai, to ise utpaadit yogya hone ke liye aksar sansaadhit karne ki aavashyakta hoti hai. aadhunik ekeekrut paripth mein, fotopratirodh ko ujaagar karne ke liye prayukt prakaash ki tarang dairdhya se chhoti visheshataaen hain. utpaadakata software, eksapojr maask mein mukt-paripth ko samaapt karne ke liye hastakshep paitarn jodte hain aur maask ke rijaulyooshan aur kantraast mein vruddhi karte hain.


ZDNet ke anusaar, aalochakon ka maanana hai ki is praudyogiki se kisi vyakti ki har gatividhi par nazar rakha jaaega aur yeh gopaneeyata par ek aakraman hoga. vivaad is baat par hai ki aalochak maanate hain ki sarkaar dvaara iska durupayog hoga. kuchh log aise bhavishya ki avadhaarana pesh karte hain jahaan har gatividhi par sarkaar ki nazar hogi.[86] Cathrine albrekt ke spaaichips: how major korporeshan end gavarnameint plaan tu track yor evri moov vith RFID, se ek vyakti ko "gair-nijta waali duniya ki kalpana" ke liye protsaahit kiya jaata hai. "jahaan aapki har khareed ki nigraani aur ek detaabes mein darj ki jaati hai aur aapki har cheej sankhyaabaddh hai. jiske tahat, kisi anya sudoor raajya ke ya shaayad kisi doosare desh ke vyakti ke paas aapki har khareed ka byaura hoga. aur kya, unka pata lagaaya ja sakta hai aur door se najar rakhi ja sakti hai."[87] seedhe shabdon mein kahein, shadayantrakaareeyon ka tark hai ki RFID chip ke saath sarkaar ek vyakti ko bhaan hue bina hi usaki gopaneeyata bhang kar sakti hai.
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]

This forced him to quit his studies after finishing 7th standard in school and college[9] He started working by helping his elder brother in a village tailoring shop. Later he took up the job of meshing coir to make ropes at a coir factory.[10][11]
aam taur par dendaari lekhon ke karmiyon dvaara gban rokane ke liye, durupayog ke khilaaf vividh jaanch maujood hain. kartavyon ka pruthakkaran ek aam niyantran hai. lagbhag sabhi companiyon mein check ke sansaadhan aur mudran ke liye ek junior karmachaari aur check ke punareekshan aur us par hastaakshar karne ke liye ek varishth karmachaari hota hai. aksar, lekhaankan software pratyek karmachaari ko keval unhein saunpe gaye kaarya ko nishpaadit karne tak hi seemit karte hain, taaki aisa koi jriya maujood na ho, jisse koi karmachaari - niyantrak bhi - akele koi bhugataan kar paae.
EPCglobal ke abhiyaanon mein se ek tha 1990 ke dashak mein RFID duniya mein prachalit protokaul ke kolaahal ko saral karna. do taig air intarafes (ek taig aur ek reedar ke beech soochana ka aadaan-pradaan karne ke liye protokaul) ko EPCglobal dvaara 2003 se pehle paribhaashit (lekin pushti naheen) kiya gaya. in protokaul ka, jinhein saamaanyat: class 0 tatha class 1 ke roop mein jaana jaata hai, 2002-2005 mein mahatvapoorn vyaavasaayik kaaryaanvayan hua.
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.

RFID ke kai pustakaalaya anuprayog hain jo atyadhik laabhakaari ho sakte hain vishesh roop se parisancharan karmachaariyon ke liye. choonki RFID taig ko kisi vastu ke andar se bhi padha ja sakta hai, kisi saamagri ko scan karne ke liye kisi kitaab ke aavaran ya DVD ke khol ko kholne ki jaroorat naheen hai. isse ripteeteev motion injureej ko kam kiya ja sakta hai. jahaan pustakon ke oopar ek baarakod hai, vahaan abhi bhi yeh suvidha hai ki lenevaale ek kitaab ko ek baar mein karne ki bajaae, pustakon ke ek poore dher ko ek baar mein scan kar sakte hain. choonki RFID taig ko gati mein bhi padha ja sakta hai, RFID reedar ka upayog lautaai gayi saamagri ki kanveyar belt par rahate hue jaanch karne se karmachaari samay mein bachat hoti hai. lekin, jaisa ki baarakod ke saath hai, yeh sabhi lenevaalon ke dvaara swayam hi kiya ja sakta hai jiska arth hua ki unhein fir kabhi karmachaariyon ki sahaayata ki jaroorat na ho. ek nishchit sthaan ke in reedar ke alaava portebal reedar bhi hain (laaibreriyn ke liye, lekin bhavishya mein sanbhavat: lenevaalon ke liye bhi, sanbhavat: yahaan tak ki unke swayam ke saamaanya-uddeshya vaale reedar). in sab ke saath, vastusoochi ko kuchh second ke bheetar, saamagri ke ek poore shelf par kiya ja sakega, jiske tahat ek bhi pustak ko aalamaari se hataana naheen padega.[30]. amyo, sveedan mein, RFID ka istemaal netraheenon ke liye shravya pustakein lene ke liye kiya jaata hai.[31] Malaysia mein, malteemeediya university laaibreri, saaibarajaya mein pustakon ka sateek sthaan ingit karne ke liye smart shelvs ka prayog kiya jaata hai.[32] Netherland mein, haath mein pakade jaane vaale reedar ko is uddeshya ke liye shuroo kiya gaya 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.
