All the latest Canadian dollars have a vertical holographic security film on the left. You can see the face value of color-changing maple leaves and banknotes from different angles.
In the portrait on the right side of the holographic bar, you can see the words of the Bank of Canada in English and French under the irradiation of purple light, as well as figures with face value (the printing here is weak, and it needs to be seen clearly in the dark and under high-power purple light). Fluorescent fibers are everywhere in the whole banknote.
There are figures with face value on the front, and there are micro-printed words in many other places.
In the middle of the white watermark window, you can see the head watermark of the main scene map with face value and the white watermark with face value number.
On the right side of the watermark window, there are double-sided printed patterns with face value numbers, and you can see that the patterns on both sides of the banknote are spliced into face value numbers.
On the left side of the back, you CAN see the window-changing security line with the word can printed on it. The color of the security thread changes between green and yellow at different angles.
