Dear Friends :
I urge you to find a few minutes from your busy
schedule to go through following exchange of emails between me and Qiu Jiang - a researcher at KAUST ( King Abdullah University of Science and
Technology – Saudi Arabia )
As far as possibility of embedding RFID sensor in high
denomination currency notes is concerned , earlier I had also exchanged mails
with MIT researcher, Sanjay Sarma ( reproduced below )

Dear Qiu / Jr-Hau He,
I read about your research on this subject at :
Congratulations on a discovery of ( possibly ) ,
immense economic consequences
Here is what I have in mind :
Corruption is the biggest economic evil , which
continues to fuel “ inequity “ among the rich and the poor
Corruption starts with tax
evasion and subsequent use of Black
Money generated – most of which , is in the form of high denomination currency notes , piling up in
the cabinets and vaults of the tax-evaders
Currently , there is no technology
to trace / track such piles of hidden high denomination currency notes ,
although there has been lots of “ talk “ on embedding such currency notes with RFID sensors , to enable tracking
Some months back , an officer of the Australian
Government announced intention to do just that
I have , myself , been urging the Indian Government
for over 2 years , to embed RFID in newly
printed notes of Rs 500 and Rs 2000
But , I understand , RFID
need a source of power , in order to “ announce “ its location
And , so far , it has not been possible to embed a battery within the thin currency notes ,
which can power RFID
Is it possible that one of these days , your research
can supply such power to embedded RFID ?
I would highly appreciate your views on this
With Regards,

Subject: Re: TENG / Triboelectric Nanogeneratot
Dear Hemen:
The typical power consumption of RFID is ~10 µW,
and Energy density of a microcapacitor can easily go 1 mWh/cm3, which means a
microsupercapacitor with 1 cm3 volumn can power the RFID for 100 h. As you
said, you want some thin devices, take 100 µm thickness for example, a
microsupercapacitor with 1cm2 area and 100 µm thickness can power the RFID
for 1h.
Also, you don't need to
continuously power the RFID, thus it is practical to do so.
Regards
Qiu

Dear Qiu,
Many thanks for your very prompt – and
clear – reply
India’s Rs 2,000 currency note is 110
micron thick
And 1 cm sq area for embedding
microsupercapacitor , should not pose any problem
Extremely thin RFID sensors are also
available – and getting as cheap as few cents a piece
But since the charge from
microsupercapacitor can power that RFID for only 1 hour , it may not be of much
use if that pile of currency notes is just lying in a cabinet / vault
Although, if that currency note is lying
in a wallet / purse and handled , now and then ( in order to make “ cash
payments “ ) , then I suppose it will build up the charge in
microsupercapacitor and power the RFID
Am I correct ?
Warm Regards,

REPLY from Qiu :
Re: TENG / Triboelectric Nanogeneratot
Correct, to continuously power the RFID over a long
period, integrating solar cell or a triboelectric nanogenerator with the
supercapacitor is a good option, and we are doing lots of research to optimize
and stabilize the performance.

Dear Snjay :
On 25 March 2016
, you wrote to me :
Dear
Mr. Parekh,
Yes,
placing tags on money has certainly been considered in the past.
I
think it is a matter of time before it happens.
I
do agree with your idea.
Having
said that, as more and more transactions become digital (credit cards, bitcoin,
Adhaar card, etc.) the need for tracking cash goes down — ironically as our
ability to track it increases.

Once again , Govt of India is planning to re-introduce , Rs 1000 / - currency note
I thought of checking up with you , whether technology
( of embedding RFID chips into currency notes )
has improved since you wrote and whether any country has made a beginning in
this direction
I will appreciate your latest inputs
