Since the Estonian ID-card infrastructure has been around almost 20 years (didn't even realize it's been this long already), it's used literally everywhere. Every time you interact with the government or a bank, utilities or even loyalty programs at stores, you'll use your digital ID.

These days, you also have the option of signing with Mobile-ID (using a secure SIM application provided by your phone carrier) or SmartID (a regular Android/iPhone app) are probably more convenient since you don't need the smart card reader.

I can't remember the last time I had to physically sign something in Estonia, only when dealing with foreign companies, where you need to pretend to print, sign & scan the document. They don't seem to mind copy-pasted PDF signatures though...

Oddly enough both of my leases in Estonia have wanted a hand-signed copy (though both times I also did the digital PDF signature). No clue why, but I can't remember anything else that ever has...
