Square has released their Square Card Case app today, which allows anyone to open up a tab at a local merchant and pay without having to swipe their credit card. The Square Card Case works by allowing users to enter their credit card details into their Square account.
Once at a local merchant who uses the Square Register app, users can start a tab. When the tab is created, the user's name will appear on the merchant's Square device. When the user is ready to check out, the merchant simply touches the user's name on the Square Register app where the transactions are tallied and paid for using the Card Case user's credit card on file. Upon completion of a transaction, a digital receipt is sent to the email address on file.
A big plus of using Square Card Case is the ability to pay at local merchants right from your iPhone. However, right now, the Card Case app is only useful if you live in New York City, San Francisco, Washington D.C., Los Angeles or St. Louis. But as more merchants start using Square, the Card Case app is sure to catch on. Square Credit Card users don't have to worry about any extra fees on their end either. Like using a regular credit card, Square charges the merchant per transaction.
Square today also updated their Square credit card reader app. The update offers improved transaction speeds, no signature required for transactions $25 or less and the ability to enter $0.00 transactions (useful for when the merchant wants to keep track of items, but doesn't charge for them -- like a free bottled water when you buy a hotdog). The Square Card Case app and the Square credit card reader app are free downloads in the App Store.
