Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

FW: DATA STORAGE ON CLOTHS WITHOUT ELECTRONICS


Dear Shyam,


I suppose your busy schedule must have kept you from responding to my following mail

But do let me have your views , as soon as time permits  , on this matter of national importance


Warm Regards,

Subject: DATA STORAGE ON CLOTHS WITHOUT ELECTRONICS

Dear Shyam,


In yesterday’s “ Mumbai Mirror “ , I came across following news :

New Fabric can store data without electronics


I also looked it up on your web page : https://homes.cs.washington.edu/~gshyam/  and saw the video and then wondered :

“  Can your technology help the Indian Government , tackle the twin problems of ,

·          Detection of fake / forged currency notes of high denominations ( Rs 500 / 2,000 )

·         Reduction of BLACK MONEY ( usually held as CASH of Rs 500 / 2,000 notes )



Earlier , I had suggested to the Indian Authorities to consider embedding RFID nano-chips in those notes , to track any accumulation of ( say ) 1000 notes in an area of 1 sq meter , anywhere in India


The idea of embedding RFID was considered “ feasible “ by Sanjay Sarma


Only a few days back , I learned that the Australian Government is considering embedding RFID nano-chips in its $ 50 / 100 , currency notes for the purpose of tracking the Black Money


In “ Mumbai Mirror “ news item , you are quoted :

“  This is a completely electronic-free design , which means you can iron the smart fabric or put it in the washer and dryer. We are using something that already exists on a smart phone and uses almost no power, so the cost of reading this type of data is negligible


Report further says :

“ The team also demonstrated that the magnetized fabric could be used to interact with a smart phone while it is in one’s pocket … Scientists realized that this off-the-shelf conductive thread also has the magnetic properties that can be manipulated to store either digital data or visual information like LETTERS or NUMBERS


I believe all currency notes come with a metallic SECURITY THREAD , capable of being magnetized


So, could that thread be able to store the UNIQUE SERIAL NUMBER , assigned to each and every currency note , which , in turn , can be “ read “ by the Smart phone , and “ transmitted “ to the Central Server of the India’s Income Tax Department ?


If possible , this can track those high denomination currency notes lying in wallets / purses ( - assuming that a smart phone is also next to those notes )


This still leaves open the following issue :

Huge bundles of high currency notes ( totalling millions of rupees ) , are usually stored in lockers ( at home or in bank vaults )

How can your invention help to track these ?


I would highly appreciate if you can show a way  by which India can leapfrog Australia


My idea is explained at length at :
