A trusted friend or relative organizes it, people chip in by card from a link, and the total is visible to the group. This is a private collection among people who know the person, not a public charity appeal, so the organizer controls the money and hands the full amount to the person who needs it.
When someone you know is hit with medical bills, the people around them want to help quietly and quickly. That's different from a public fundraiser aimed at strangers, it's a closed circle of friends, family, and coworkers who already know the person and just want to get money to them cleanly. The problem is the collecting: cash, Venmo, checks, and one friend trying to keep it all straight.
A public site puts the person's situation in front of strangers and takes a cut on the way through. A private collection among people who already know them keeps it dignified and keeps the organizer in control of when and how the money reaches the person. Contributions don't have to be broadcast with amounts attached, and what reaches the person is simply given, help from people who care, not a campaign.
Because the organizer holds the money and decides what leaves, this stays a group of trusted people helping one of their own, not open payments between strangers. TableCash never holds the money; it moves through Stripe to the organizer, and the app is the record everyone who gave can open. Weighing this against a public campaign?
