Most of my finances are just strings of 1s and 0s. My company pays me. They don't send pieces of paper to my bank. It happens via 1s and 0s. From there, 80-90% of my expenses get paid automatically (rent, most taxes, electricity, internet, gas, water, trash collection) all via 1s and 0s. And cash is slowly disappearing into 1s and 0s as well via phone payment systems.
