Germany's New Matrixcode Stamp

On 18th February I got not only four postcards but also a cover from Germany.

I sent this cover to myself and used our new stamp about Digital Change (issued 04-02-2021). This is the first German stamp with the new Matrixcode. Starting next year, every new German stamp will be defaced by this ugly code that enables an unnessecary and poorly working very rudimentary tracking function. I actually like this new stamp, but hate the idea that soon every stamp will get such a code. Luckily this year only a few stamps will get it. This stamp was issued in two versions, gummed and self-adhesive. Used here is the self-adhesive version with its First Day of Usage Postmark.
