Before mobile card readers, a small, mobile, or newly started business often genuinely couldn't accept card payments at all — the equipment and merchant accounts were built for larger, established retailers.
Making card acceptance available to anyone
Square's core product was a small card reader that plugged into a phone, paired with a simple sign-up process, that let a farmers market stall or a food truck start accepting cards the same day, without the paperwork and underwriting a traditional merchant account required.
What it meant beyond convenience
Cash-only businesses lose sales from customers who simply don't carry cash. Letting the smallest, newest businesses accept cards the same day they opened removed a real barrier to running a small business at all, not just a convenience for existing ones.
It's a reminder that a lot of valuable software isn't about adding a new capability — it's about making an existing one available to people who were previously locked out of it by paperwork and scale requirements.
