We pulled this data from the Twitter account of Jonathan's Card (http://jonathanstark.com/card), taking the location of each twitter account that was mentioned in a tweet by @jonathanscard. This should more or less be the locations of people that are recharging the card. Tweets gathered between the dates of July 18 - August 7.
Hey Jonathan, any chance there's a store location available when you view each transaction on the card? Now that would make an interesting map.
