I was reading the article on the internet about RFID chips - they also discuss about this topic on the recent Report of Business Magazine (November 2006) for various goods, credit cards, money, etc.   Recently (about 3 days ago) on CBC News, they talk about credit cards in Canada with RFID chips that may prevent copying of credit cards.   I then read some articles on the internet using Google Search and found one from 2001.  It is believed that the US Currency have RFID chips imbeded in higher denominated currency.  

Does anyone think that the Bank of Canada will implement such devices in their notes?  

[size=16]Euro bank notes to embed RFID chips by 2005[/size]

SAN MATEO, Calif. — The European Central Bank is working with technology partners on a hush-hush project to embed radio frequency identification tags into the very fibers of euro bank notes by 2005, EE Times has learned. Intended to foil counterfeiters, the project is developing as Europe prepares for a massive changeover to the euro, and would create an instant mass market for RFID chips, which have long sought profitable application.

The banking community and chip suppliers say the integration of an RFID antenna and chip on a bank note is technically possible, but no bank notes in the world today employ such a technology. Critics say it's unclear if the technology can be implemented at a cost that can justify the effort, and question whether it is robust enough to survive the rough-and-tumble life span of paper money.

A spokesman for the European Central Bank (ECB) in Frankfurt, Germany confirmed the existence of a project, but was careful not to comment on its technologies. At least two European semiconductor makers contacted by EE Times, Philips Semiconductors and Infineon Technologies, acknowledged their awareness of the ECB project but said they are under strict nondisclosure agreements.

The euro will become "the most common currency in the world" at midnight on Jan. 1, when 12 nations embrace it, according to Ingo Susemihl, vice president and general manager of RFID group at Infineon. The ECB and criminal investigators in Europe are already on high alert, worried not only about counterfeiting of a currency most people haven't seen, but also of a possible increase in money laundering, given the euro's broad cross-border reach.

The ECB said 14.5 billion bank notes are being produced, 10 billion of which will go into circulation at once in January, with 4.5 billion being held in reserve to accommodate potential leaps in demand.

Thwarting underworld popularity

Although euro bank notes already include such security features as holograms, foil stripes, special threads, microprinting, special inks and watermarks, the ECB believes it must add further protection to keep the euro from becoming the currency of choice in the criminal underworld, where the U.S. dollar is now the world's most counterfeited currency. The ECB spokesman said his organization has contacted various central banks worldwide — not just in Europe — to discuss added security measures for the currency.

In theory, an RFID tag's ability to read and write information to a bank note could make it very difficult, for example, for kidnappers to ask for "unmarked" bills. Further, a tag would give governments and law enforcement agencies a means to literally "follow the money" in illegal transactions.

"The RFID allows money to carry its own history," by recording information about where it has been, said Paul Saffo, director of Institute for the Future (Menlo Park, Calif.).

The embedding of an RFID tag on a bank note is "a fundamental departure" from the conventional security measures applied to currency, Saffo said. "Most currency security today is based on a false premise that people would look at the money to see if it is counterfeit," he said. But "nobody does that. The RFID chip is an important advance because it no longer depends on humans" to spot funny money.

RFID basics

The basic technology building blocks for RFID on bank notes are similar to those required for today's smart labels or contactless cards. They require a contactless data link that can automatically collect information about a product, place, time or transaction. Smart labels produced by companies such as Philips Semiconductors, Infineon, STMicroelectronics and Texas Instruments are already used in such applications as smart airline luggage tags, library books and for supply chain management of various products.

"Two minimum elements you need for RFID are a chip and an antenna," according to Gordon Kenneth Andrew Oswald, associate director at Arthur D. Little Inc., a technology consulting firm based in Cambridge, Mass. When a bank note passes through reader equipment, the antenna on the note collects energy and converts it to electric energy to activates the chip, he said.

The antenna then "provides a communication path between a chip on the bank note and the rest of the world," said Tres Wiley, emerging markets strategy manager for RFID Systems at TI. For its part, the chip "is a dedicated processor to handle protocols, to carry out data encoding to send and receive data and address memory" embedded on the chip.

Although the industry is "well down the road with the smart label technology," Wiley said he was "a bit surprised to learn that someone goes to that extent — to embed RFID into bank notes — to combat counterfeit money."

A number of challenges must be overcome before RFID tags can be embedded on bills, said Kevin Ashton, executive director of the Auto ID Center at the Massachusetts Institute of Technology. "The most obvious one is the price," he said. Today's RFID tags cost between 20 cents to $1.00, and "that's not economic enough for most bills," Ashton said. "We've absolutely got to get the cost way down." The goal of the Auto ID Center is to find an application that requires billions of RFID chips to bring their cost as low as 5 cents, he added.

While most chip companies with RFID expertise are keeping their plans for money applications close to their chest, Hitachi Ltd. announced plans last July for a chip designed for paper money that would pack RF circuitry and ROM in a 0.4-mm square circuit measuring 60 microns thick. Although the chip features no rewritable capability, Ryo Imura, chief executive of Hitachi's Mew Solutions venture, said at the time of announcement, "We'll consider them for the next generation of products." Hitachi's chip stores encrypted ID information in ROM during the manufacturing process, presumably to replace the serial number of each bank note.

Even without writable memory, Hitachi's chip is said to be fairly costly. Hitachi declined to be interviewed for this article.

While the size of the rewritable memory embedded on an RFID chip will determine the kinds of information it can store, it also affects the chip's cost.

Affordable with bigger bills

It is unclear whether the ECB will incorporate RFID chips into all euro bank notes or just on the larger bills. The EUR 200 and EUR 500 bank notes in particular — equivalent to roughly $200 and $500 in value — are expected to be popular in the "informal" economy. Embedding a 30 cents chip into a EUR 500 bill would make more sense than putting it into a European buck, several industry sources said.

Manufacturing processes are also considered a major hurdle to embedding a low-cost antenna and chip onto bank notes. "The chip is already so small," MIT's Ashton said. "To connect the two ends of a coil — an antenna — at precisely the right place on a chip could present a major problem."

A printing process is an option, Ashton said, but "you need a breakthrough in the high-volume manufacturing process." Such a technology does not exist today, he said.

Size and thickness are key attributes of an RFID chip for paper currency, said Karsten Ottenberg, senior vice president and general manager of business unit identification at Philips Semiconductors. "For putting chips into documents, they need to be very small — less than a square millimeter — and thin such that they are not cracking under mechanical stress of the document. Thinning down to 50 micron and below is a key challenge." That would require advanced mechanical and chemical techniques, he said.

Bank notes present "an interesting future application for us," said Tom Pounds, vice president of RFID projects at Alien Technology, which holds the rights to a fabrication process that suspends tiny semiconductor devices in a liquid that's deposited over a substrate containing holes of corresponding shape. The devices settle on the substrate and self-align. Rather than working on the interconnection to an RF antenna one chip at a time, "we can do a massively parallel interconnection," Pounds said. Bank notes are not Alien's primary focus at present, he said.

I think the $20 new US bills have an RFID chip embedded in one of Jackson's eyes.
I recall an article I read where someone microwaved a $20 bill to see which eye exploded (I assume the microwave is trashed after that so do not try at home).

This allows retailers to do a wallet biopsy as shoppers enter the store so they know who the customers they should target are.

Also, most upscale casinos in Las Vegas have RFID chips in the chips so that when players play with their loyalty card, the casino can keep track of their bid amounts (even with money plays with the new cash) with the RFID readers so they know who to send promotional offers to and to catch the whales.

So does this mean that if someone had a portable scanner, and pointed it at your home, they would not only know how much money you have there, but all the serial numbers for each note as well?

I do not know enough about the technology. I think you have to be in a certain range. I guess this technology is used for automated checkouts out of store so as you walk past the checkout aisle, all your items could be tallied up and it taken off a debit or credit card with a chip embedded. If these were active over longer ranges, everyone in the store would be paying for everyone else's purchases.


But indeed it is a scary thought if the ranges are long enough.

The range for most RFID stuff is less than a foot, but depending on the application, it could be a few metres (think of store merchandise protection equipment... They have the scanners a couple metres apart as you walk out the store.) Long-range RFID detection is rather uncommon.

Gaming chips in Ontario casinos already contain a small microchip of some sort. Several counterfeiters have been caught so far. I don't understand the techonogly, but it exists and is in use. To make this small enough to work in banknotes will come soone or later.

Yes, that is the article. Must be his right eye then.

I just stuck a few new journey $5 notes in the microwave.

The foil strip pops, sparks and burns within 1-2 seconds, nothing else happens after that.

I've only tried with 2 notes so far, so it's hard to say, but I seem to have a uniform burn spot directly underneath the tiny lion just below the crown at the top of the lithographed coat of arms.

Made a popping sound just like the article about the US and Euro notes.

Has anyone else tried this with the same results?

No...sadly, I'm afraid that I don't have money to burn!  :-[ :'( ;)

I wonder if the new TTC tokens for the Toronto subway system have RFID chips in them.  They are said to have some kind of security device embedded in them, but no details have been released (for obvious reasons I suppose).  I might try nuking a TTC token to see what happens...

I tried to burn a new note in a microwave oven and, effectively, the holographic strip burns, but unevenly.  The pattern of burnt spots are essentially randomized....  The security thread is left unharmed.   I don't think that there is any RFID in the note...
