computer aarkitekchar ek vishesh engineering gatividhi hai jo rajistar, aakalan laujik, bason aur computer ke anya bhaagon ko kuchh prayojan ke liye sabse achhe tareekon se shreneebaddh karne ki koshish karta hai. computer vaastukaar ne laagat kam karne aur gati ko teevr karne aur computer prograaming trutiyon ki pratirksha ke liye computer ke design mein vruhad maatra mein suprayog ko lagaaya hai. aur teji se baitari paavard computer pranaali mein bijli ko kam karna iska saadhaaran uddeshya hai. kai computer aarkeetek maaikroprograamars ke roop mein vistrut prashikshuta ki seva de rahe hain.
udaaharan ke liye, kuchh laujik parivaaron mein, NAND gate, nirmaan hone vaale saralatam digital gate hain. anya sabhi laujik waali kaarravaai NAND gate dvaara kaaryaanvit ki ja sakti hain. yadi ek sarkit ko pehle se hi ek NAND gate ki aavashyakta hai aur ek ekal chip aam taur par chaar NAND gate rakhata hai, to baaki ke gate ko anya laujik kaarravaaiyon ko jaise laujikl end laagoo karne ke liye prayog kiya ja sakta hai. yeh, un vibhinn prakaar ke gate se yukt chip ki aavashyakta ko samaapt kar sakta hai.
RFID taig ka istamaal jin tol booth par electronic tol sangrahan ke liye kiya jaata hai unamein shaamil hain jaurjiya ka krooj card, California ka faasatraik, Colorado ka E-470, ilinois ka I-paas, oklaahoma ka paaikapaas, vistaar karte poorvi raajyon ka E-ZPass pranaali (maisaachusets ke fast len, delaaveyar, new haimpashaayar tarnapik, maireelaind, new jersey tarnapik peinsilveniya tarnapik, vest varjeeniya tarnapik, New York ki throove pranaali, varjeeniya, main tarnapik aur rode dweep ke nyooport brij sahit), sentral florida bhi is takaneek ka istemaal apne E-PASS pranaali ke maadhyam se 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.
FDA ke anusaar, RFID chip ka pratyaaropan se chikitsa sambandhit sambhaavit khatre bhi hain. bijli ke khatre, MRI asangati, pratikool ootak pratikriya aur pratyaaropit traansapondar ka pravaas, kuchh sambhaavit khatre hain jo vereechip ID pratyaaropan upakaran se jude hain, khaadya evam aushadhi prashaasan (FDA) dvaara jaari ek 12 October 2004 ke patra ke anusaar.[47]
