January 2004 mein, CASPIAN ke gopaneeyata ke pairokaar aur jarman gopaneeyata samooh FoeBuD ko Germany mein METRO future store mein aamantrit kiya gaya, jahaan ek RFID pilot pariyojana laagoo ki gayi thi. sanyog se yeh khulaasa hua ki METRO "pebaik" graahak lauyalti card mein graahak ID vaale RFID taig shaamil the, ek tathya jise na to card praapt karne vaale graahakon ko bataaya gaya aur na hi gopaneeyata ke pairokaar is samooh ko. yeh METRO dvaara is aashvaasan ke baavajood hua ki kisi graahak pehchaan deta ko track naheen kiya ja raha hai aur sabhi RFID upayog ko spasht roop se bataaya gaya hai.[75]

jyaadaatar maamalon mein sanketo ki avastha ki sankhya do hoti hai aur in do avasthaaon ko do voltej staron dvaara darshaaya jaata hai: prayog mein aapoorti voltej ke aadhaar par ek va doosra (aamtaur par "jameeni" ya shoonya volt ke roop mein kaha jaata hai)| 1 uchch star par hota hai va 0 nimn star par. aksar ye donon star "lo" aur "haai" ke roop mein pratinidhitv karte hain.

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.
poore Europe mein aur vishesh roop se peris mein (pranaali RATP dvaara 1995 mein shuroo ki gayi), lion, bordo, grenobal, nainsi aur maarsile France mein, poore purtagaali raajamaarg vyavastha mein aur kai purtagaali saarvajanik car park mein, Milan, turin, Italy mein nepals aur floreins aur Belgium mein brasels, kailipso antararaashtreeya maanak ke anuroop RFID paas ka saarvajanik parivhan pranaali ke liye upayog kiya jaata hai. unka upayog ab Canada (mauntriyl), maiksiko, isaraail, Columbia mein bogota aur parera, naarve mein stavaangar, laksamabarg, aadi mein bhi kiya jaata hai.

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.
