I recently became an e-Resident of Estonia. To do so, I had to apply online, pay €100, go through some identity checks, then visit the Estonian Embassy in London. The nice lady in the basement checked my UK passport, took a digital thumbprint and gave me a box containing my e-Residency card, which looks like a credit card, and a small plastic gizmo which enables me to connect the card to a computer using a USB port.
