b.c. anti-counterfeit company develops tech to put moving 3d holograms on bank notes
A Canadian security company is at the forefront of nanotechnology, and one day, the company may place 3D holographic photos on banknotes, making it almost impossible to copy the bills.
The 4D Lab at Simon Fraser University is only $4. 5-
One of the world\'s handful of million-beam flat-panel machines capable of creating smaller details than optical wavelengths --
Each pixel is not visible to the naked eye, but this level of resolution allows engineers to create color 3D holographic images that are difficult to miss.
Bank notes in Canada already have a variety of security features, including 2D holographic strips.
However, copying these with a laser printer is relatively cheap, and making 3D holographic photos of this size requires a lot of mechanical knowledge and millions of dollars.

Based on nanotechnology security, 3D holographic photos are being placed on their banknotes in collaboration with the G7 countries.
He took Canada\'s $20 bill as an example.
\"Imagine if Queen Elizabeth had a full color image she turned and looked at you and blinked at you.
He said: \"Due to the working principle of this technology, this mobile holographic image will be very difficult to copy.
The first step is to use an electronic beam tablet, sometimes known as an electronic beam tablet.
Beam Machine, create a template.
The template is the template of the holographic image. The e-
Beam machine creates a template by creating a pattern on a silicon wafer that is coated with electronic-sensitive materials.
The focused electron beam produces patterns in very detail on the wafer-
Each \"pixel\" is 10,000 times smaller than the width of human hair. Inside a one-square-
There could be billions of CM images.
It\'s called pixels, says Landrock.
Next, the template is used to create a print-
Like a stamp, press the style block and can then be used to print thousands of bills.
There are a few e-

Beam machine can print 10 to 10 cm size images in one day, opening the possibility for real-world use.
The resulting hologram is very bold and very prominent.
\"You can\'t miss it,\" landlock said . \".
This is the key to any security function, he explained.
He said: \"Unfortunately, most Canadians I interviewed, when I asked them what you think about the holographic photo on our Canadian notes, they said they didn\'t know it had Holographic
\"For me, this is a complete failure of what security technology should do.
\"But with 3D holographic photos, even a person who only has a few seconds to study the bill can find it, or notice if it\'s not there,\" Landrock said.
This will be a nightmare for counterfeiters.
Landrock estimates that it will cost about $100 million for criminals to buy the necessary machines and reverse engineer proprietary algorithms to make 3D holographic images.
\"I am very confident that if someone is really committed to it, it will take three to five years to get close to it.
\"This new technology joins the central bank\'s list of security features to invest in limiting the number of counterfeit currency in the country.
For example, since the introduction of the $20 plastic banknotes in 2011, the number of counterfeit banknotes in Canada has dropped sharply.
According to the RCMP, police found about 17,000 counterfeit banknotes on 2016 and 2017, compared with 62,000 on 2014.
Antweiler said that\'s why many businesses that have rejected $50 and $100 bills in the past now accept them.
But authorities have been engaged in a \"technical arms race\" with counterfeiters, said Werner Antweiler, an economist at the School of Business at the University of Columbia.
\"As Bank of Canada and other central banks are adjusting new measures to make counterfeiting more difficult, you will see counterfeiters trying to catch up,\" he said . \".
\"They are looking for ways to imitate things to confuse people who are not active.
But Landrock says 3D holographic images on bank bills will soon become a reality.
\"We will see this in the coming years.
