I inserted a small magnet into the token of the shopping cart so that it can be hung in a suitable place for easier finding.
The token is the size of a 100 HUF coin, but I will also test it on 1 EUR devices.
Do not keep to close the magnet to your bank card or other equipped with magnetic strip gadgets.
Use a small amout of glue to fix the magnet to the token after the printing.
