RFID pratyaaropan ke saath ek aaranbhik prayog, saaibaranetiks ke british professor kevin vaaravik dvaara kiya gaya jinhonne 1998 mein apne haath mein ek chip pratyaaropit kiya. 2004 mein kaunaraad ches ne Barcelona aur rautaradaim mein apne naait club mein apne VIP graahakon ki pehchaan ke liye jo iska prayog peya ke bhugataan ke liye karte the, pratyaaropit chips ki peshakash ki.

Parakala was appointed to the NSUI central committee as All India Vice President in 1984. It was almost like a token of appreciation by the Congress High Command of his performance as President of the JNU unit and his contribution to the establishment of the organisation in the citadel of left wing student politics. As an office bearer of the central committee of NSUI, he toured several states and universities to organise the activities of the students' wing of the Congress Party. He took up a massive campaign against drug abuse in the university campuses all over the country. With his departure for United Kingdom in October 1986 to pursue his higher studies at the London School of Economics (LSE), there was a break to his political activity. On his return to India in May 1991 he resumed political activity in his native place Narasapuram in West Godavari District. Tragic political events in the country resulted in dramatic political developments. Rajiv Gandhi was assassinated in Sriperumbudur, Tamil Nadu, in the midst of the election campaign and P V Narasimha Rao was elected to lead the Congress Party. After the elections, Narasimha Rao became Prime Minister at the head of a minority government. Parakala family was closely associated with P V Narasimha Rao for a long time, Parakala Seshavataram, Prabhakar's father, being a close political associate of Rao. Narasimha Rao assigned the task of conceiving, designing and building a grand institution to perpetuate the memory of Rajiv Gandhi. He made Parakala as Officer on Special Duty to oversee the implementation of the project 'Rajiv Gandhi National Institute for Youth Development (RGNIYD). It is conceived as an institution to train the youth of India and impart to them skills that are necessary to them to play a vital role in building a modern nation in the 21st century, a theme that was dear to the heart of Rajiv Gandhi. Parakala went around the country to study various institutions, their constitutions, structures, course content etc., and designed the Institute which is functional now under the aegis of Ministry of Human Resource Development. Around this time Parakala was nominated by the Congress High Command to represent the Congress Party at the French Communist Party's Plenary in Paris.
In a gap of about two years he contested the by-election to Narsapuram Assembly constituency which arose as the sitting MLA got elected to Lok Sabha in the 1996 general elections. That by-election was a closely fought election and Parakala lost it narrowly. Inner party squabbles and bickerings led to Parakala's exit from Congress Party. He joined the Bharatiya Janata Party (BJP) in late 1997. BJP hardly had a presence in the state and especially in West Godavari District. He contested the ensuing 1998 Lok Sabha election from Narasapur Lok Sabha constituency, and not surprisingly, lost. He played an active role in the party affairs, became a spokesperson of the state unit, and went on to become a member of the BJP's national economic cell that guided the party's economic policy. He was also made a member of a task force of the Planning Commission of India that formulated the Xth Fiver Year Plan.
radio-aavrutti pehchaan (angreji: Radio-frequency identification) ek vastu ka upayog hai (aamtaur par ek RFID taig ke roop mein sandarbhit) jise ek utpaad, pashu, ya vyakti mein radio tarangon ke istemaal se pehchaan karne aur traiking ke uddeshya se lagaaya ya daala jaata hai. kuchh taig ko kai meter door se aur paathak ki drushti rekha ke paar se padha ja sakta hai.
donon ke paas hi aankade seemit hain. rog niyantran aur rokathaam kendra (the seintars for dijeej control end prijrveshan) ne 2002 mein prakaashit apne anusandhaan mein daava kiya hai ki sanyukt raajya America mein beche gaye ek packet cigarette par chikitsa dekhbhaal aur utpaadak hraas par 7 dollar se adhik ki laagat aati hai. laagat aur adhik ho sakti hai jabki ek anya adhyayan mein use prati packet par $ 41 ki laagat bataayi hai, jinmein se jyaadaatar vyaktigat aur usaki/ uske parivaar ko vahan karna padta hai. is tarah se ek anya aur adhyayan ke lekhak doosaron ke liye bahut kam laagat bataate hue kehte hain: "sankhya ke kam hone ka kaaran niji peinshan, saamaajik suraksha aur chikitsa hai- kharch ki ganana mein sabse bada kaarak samaaj hai- dhoomrapaan vaastav mein paise bachaata hai. dhoomrapaan karne vaale kam umr mein mar jaate hain aur ve vah dhan naheen uthaate jo un pranaaliyon se unhein bhugataan kiye jaate.
passport ko adhik surakshit banaane ke prayaas mein kai deshon ne passport mein RFID laagoo kiya hai. baharahaal, Britain ke chips par enkripshan ko 48 ghante ke andar tod diya gaya tha. us ghatna ke baad se aur adhik prayaas ne shodhakartaaon ko, jab passport ko uske maalik ke paas bheja ja raha ho us vakt passport deta ko klon karne ki anumati di. jahaan ek aparaadhi ko chupake se lifaafe ko kholana aur fir band karne ki jaroorat thi, ab yeh pata lage bina kiya ja sakta hai, jisse passport pranaali mein kuchh asuraksha badh gayi hai.
anukramik system iske atirikt do upashreniyon mein vibhaajit hota hai. jab ek "klauk" signal state ko parivrtit karta hai tab "tulyakaalik" anukramik pranaali ek hi baar mein state ko badal deta hai. jab bhi input badalate hain "atulyakaalik" anukramik pranaali parivartan ko prasaarit karta hai. tulyakaalik anukramik system atulyakaalik sarkit ki visheshata se bana hota hai jaise flip flop, jo klauk jab parivartan karta hai tabhi ye parivartan karta hai aur jismein timing margin ko dhyaan se design kiya jaata hai.
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. 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." 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.
