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.
2009 ki garmiyon ke baad se, do kredit card companiyaan vishesh maaicroSD card ke vikaas ke liye dalaas, Texas aadhaarit divaaisafideliti ke saath kaam kar rahi hain. jab ise ek mobile phone mein daala jaaega to yeh microSD card, ek nishkriya taig aur ek RFID reedar, donon ho sakta hai.[11] microSD daalne ke baad, ek upayogakarta ka phone bank khaate se jud jaaega aur usaka upayog mobile bhugataan mein kiya jaaega.
Britain mein, RFID praudyogiki ka upayog karke, saarvajanik parivhan ke aseemit prayog ke liye poorv bhugataan ki sanchaalan pranaali ko taiyaar kiya ja raha hai. yeh design kreditkaard sadrush paas mein antarnihit hai, jise jab scan kiya jaata hai to paas ke vaidh hone ka vivran aur us paas ke vaidh hone ke dinon ka pata chalta hai. pehli baar ise laagoo karne waali company nautingham shahar ki NCT company hai, jahaan aam janta pyaar se ise "beep card" kehti hai. iske baad ise safalataapoorvak London mein laagoo kiya gaya, jahaan "oyastar card" pe-aij-you-go yaatra ki anumati deta hai saath hi saath vibhinn samayaavadhi aur vibhinn kshetron ke liye maanya paas ki bhi anumati hai.

August, 2004 mein, ohiyo punarvaas aur sudhaar vibhaag (ODRC) ne alaanko teknolaujeej ke kaarmik-traiking takaneek ke moolyaankan ke liye $415,000 karaar ko manjoori di. kaidi, kalaai par ghadeenuma traansameetar pahaneinge jo hataane ke prayaas ko jaan sakega aur jail ke computeron ko chetaavani dega. yeh pariyojana ameriki jailon mein chips traiking ki pehli ghatna naheen hai. Michigan, California aur ilinois mein suvidhaaen, pehle se hi is praudyogiki ko apanaae hue hain.

pustakaalayon mein RFID ko lekar jis chinta ka prasaar hua hai vah gopaneeyata ka mudda hai. choonki RFID traansameetar aur reedar ke anusaar, RFID taig ko 350 feet ya 100 meter se padha aur scan kiya ja sakta hai (udaaharan ke smart lebal RFID) aur choonki RFID, freekveinsi ke vargeekaran ka istemaal karta hai (donon, taig ke prakaar par nirbhar karta hai), chinta ka vishay yeh hai ki kya samvedansheel jaankaari ko ek anichhuk srot se ekatr kiya ja sakta hai. haalaanki, pustakaalaya ke RFID taig mein koi sanrakshak jaankaari shaamil naheen hoti,[33] aur adhikaansh pustakaalayon mein prayukt taig jis freekveinsi ka prayog karte hain vah keval lagbhag das foot se pathaneeya hai.[28] saath hi, pustakaalayon ko hamesha yeh record rakhana hai ki kisne kab kya liya hai, to us maayane mein koi nai baat naheen hai. haalaanki, kai pustakaalaya in record ko saamagri ke ek baar vaapas aa jaane ke baad nasht kar dete hain. RFID, paathakon ki gopaneeyata ke is sammaan ko jatil ya samaapt kar degi. iske alaava, ek anya gair-pustakaalaya agency sambhaavit roop se pustakaalaya vyavasthaapak ki jaankaari ya sahamati ke bina pustakaalaya se nikalne vaale pratyek vyakti ke RFID taig ko record kar sakti hai. ek aasaan vikalp hai ki pustak ko ek code sanchaarit karne diya jaae jiska mahatva sirf laaibreri ke daataabes ke saath sanyojan ke roop mein ho. ek aur kadam yeh hai ki kitaab ko jab bhi lautaaya jaae to use ek naya code diya jaae. aur agar bhavishya mein reedar sarvavyaapak ho jaae to (aur sanbhavat: jude hue), chori gayi kitaabon ko laaibreri ke baahar bhi pata lagaaya ja sakta hai. taig ko hataane ko mushkil banaaya ja sakta hai agar taig itna chhota ho ki use ek (yaadruchhik) prushth ke andar adrushya roop se lagaaya ja sake, sanbhavat: prakaashak dvaara vahaan daal diya jaae.
