Square, the company behind the mobile credit card reader, is running $5 billion in transactions per year, according to Wired.
In this visualization, Wired puts together transactions that occurred over the course of an hour. The larger the circle, the larger the transaction. The color coding refers to the type of transactions that took place (eg., red for retail, green for food and groceries, orange for restaurants and bars).
The most recent number puts total Square-enabled sales at more than $5 billion per year. That gets you to about $14 million per day. Since this snapshot captures a high activity part of the day across the entire U.S (not much being sold between midnight and 5 A.M.) this one hour likely represents several million dollars in sales. Square’s take in a hour? About $60,000.
