sabse chhoti RFID chip ka record hitaachi ke naam hai jo 0.05mm x 0.05mm hai. Mu chip taig, nae RFID taig se 64 guna chhote hain.[7] vinirmaan silikaun-on-insuletar (SOI) prakriya ke upayog dvaara saksham hota hai. "dhoolakan" ke aakaar ke ye chips, 128 bit reed onli memori (ROM) ka upayog karke 38 ankon ki sankhya ko sangrahit kar sakte hain .[8] ek badi chunauti entena ko jodna hai, is prakaar pathan seema ko keval kuchh mileemeetar tak seemit kar diya.
Parakala resigned his RGNIYD assignment in 1994 in order to contest the Legislative Assembly elections from the constituency which was earlier represented by both his father and mother. That election saw the return of N T Ramarao to power with a landslide victory.Congress party was decimated in the state. Parakala lost the election with over 20,000 votes margin. Although unsuccessful, his imaginative campaign was admired and talked about throughout the state. Perhaps for the first time a constituency-level manifesto was released for Narasapuram. A short campaign video specially shot for the election was released and exhibited throughout the constituency by moving television sets and video cassette players manually from place to place. Audio cassettes of Parakala's public speeches were widely circulated in the constituency. Such campaign techniques were quite rare, although not completely unknown, during those days when even the television penetration was very low.

The anti-reclamation stir launched by the Kerala State Karshaka Thozhilali Union (KSKTU) at Mankompu in 1996–97, under the leadership of Achuthanandan created much controversy. This stir was claimed to be highlighting the serious problem of the massive conversion of paddy fields into other type of land, affecting the food security of the Kerala. But this soon developed into a crop destruction drive. The protest got the sobriquet following the violent methods and crop destruction resorted to by the KSKTU cadre. The stir attracted lot of public attention and Achuthanandan was forced to express his disapproval of any destruction of crops. 15 Years later, in November 2011, a UDF Minister, who is politically opposed to Achuthanadan, justified this struggle.[36] JanataDal Socialist leader and minister for Agriculture, K.P. Mohananan, MM,said, such a struggle was necessary as Conversion of Paddy fields to other type of crops is a serious concern.
fir bhi anya kootlekhit protokaul, anadhikrut paathakon ke khilaaf gopaneeyata haasil karne ke prayaas mein hain, haalaanki ye protokaul abhi anusandhaan charan mein hain. RFID taig ko surakshit karne mein ek badi chunauti, taig ke bheetar kampyooteshanal sansaadhanon ki kami hai. maanak kootalekhan takaneek mein adhikaansh kam keemat vaale RFID upakaranon mein upalabdh sansaadhanon ki tulana mein adhik ki aavashyakta hoti hai. RSA security ne ek prototaaip upakaran ko peteint karaaya hai jo sthaaneeya star par ek maanak takkar parihaar protokaul ke dakhal se RFID sanketon ko jaam kar deta hai, or prayokta ko agar vaanchhit ho to pehchaan rokane ki anumati deta hai.[64] vibhinn neetigat upaayon ka bhi prastaav kiya gaya hai, jaise ki RFID taig waali vastu ko ek udyog maanak lebal ke saath chihnit karna. RFID suraksha, kuchh varshon se ek bahut sakriya anusandhaan kshetr hai, jismein 2002 se lekar aaj tak 400 se adhik vaigyaanik pepar prakaashit kiye gaye hain. is kshetr mein sandarbh ki ek vyaapak soochi RFID Security and Privacy Lounge mein pai ja sakti hai.
