rekheeya paripth ki tulana mein aankik paripth ko istemaal karne ki vajah iska ek laabh yeh hai ki shor[2] ke kaaran sanketo ka vightan naheen hota hai va unhein aasaani se bheja aur darshaaya ja sakta hai. udaaharan ke liye, 1 aur 0 ke kram mein banaaye huye lambe aavaaj ke ek sanket ko truti ke bina pun:nirmaan kiya ja sakta hai basharte sanket banaane ke dauraan paida hua shor itna na ho ki usaki vajah se 1 va 0 ko pahachaana hi na ja sake. seedi mein ek ghante ke sangeet ko kareeb 60 lakh dviaadhaari ankon (baainari dijits) ke roop mein sangraheet kiya ja sakta hai.


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.
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.
