Almost everyone knows about barcodes, they know less about QR codes. But making a QR code with the information encrypted in it is very simple. It is even easier to decrypt such code. To do this, you need a smartphone with a QR code reader installed. By the way, many readers have the function of creating a QR code. You can encrypt anything, text, link to the site, address e mail, phone, etc. Such a code with encrypted information can be placed anywhere, and it will not take up much space. Some make belts on a badge which has a QR code with information about the owner. Some even have tattoos.
Using the QR code you can congratulate a loved one. Place the congratulation on the website on the Internet, and encrypt the link to the page in a QR code, print it on a printer and stick it on a postcard.
In the place of residence of the author of this material there is a park with samples of local flora. When the question arose of how to inform about each species of tree, shrub, etc., the author remembered the QR code.
It was decided to encrypt the information in QR codes, and place them on the end parts of wooden blocks.

Step One: Wood Preparation
One of the culled trees, the master sawed a chock for ten. Then the saw cuts were dried for several months.
After drying, the end sides were sanded.
Step Two: Creating a QR Code
To create a QR code, you can use a specialized website or download the program to a computer or smartphone. The interface of such programs is usually intuitive. In the corresponding field you write down the text and click "confirm", the program will do the rest itself. Some sites provide a service even for encrypting images.
After the code is created, its mirror image must be printed on a sheet of paper, always on a laser printer.
Step Three: Image Transfer
Apply varnish in three layers.
Place the printout on the saw cut image down (it is important not to shift the sheet in the future). Smooth the sheet. Let dry for an hour.
Now you need to remove the paper.
Wet the sheet and remove the paper with a sponge. Then use a toothbrush.
Allow the workpiece to dry and repeat the operation until the paper is completely removed.
With a black marker, paint on those areas that are smeared. Coat the top with varnish.
Step Four: Fill
The workpiece has a longitudinal crack. The master closes the crack and the lower part of the workpiece.
Then it places the workpiece in a container and fills it with epoxy from all sides. It is necessary to process not only the end part, but also seal the bark with resin. Then heats the surface with a hairdryer. After drying, the resin removes the packaging and fills the surface of the wood bottom and cracks.
Step Five: Grinding
After complete drying, the workpiece is ground and waxed.
Step Six: Installation
To install information stumps, the master fixed them on metal racks.
