Squareup by Square is an iPhone/iPad and Android mobile credit card payment service that uses a small and inexpensive physical reader (aka credit card machine) that plugs into the audio jack of an iPhone or iPad. This page brings together the latest news, reviews, blog posts,Twitter tweets, and videos about the new SquareUp service widely released on May 11th for both iPhone and Android operating systems.

Mobile payment services are growing in popularity as smartphones, particularly the iPhone, extend the geographical range where transactions can take place. SquareUp is envisioned for mobile merchants such as artisans in a street fair or a person-to-person transaction (e.g., Craig's List). Wired magazine suggests SquareUp has the potential to be disruptive.

There has been unprecedented demand since the May announcement so the readers have been tough to get.  Also, the volume of transactions has resulted in issues with fraud and chargebacks.  Square limited the transaction to $60 in June until the credit risk infrastructure became more solid sometime in August it appears.  See June 18th letter.  [Update - deliveries of the reader have picked up substantially in early October]

The potential market is huge and SquareUP could be supplanted by RFID-enabled payment services on smartphones.  Bloomberg is reporting that AT&T, Verizon, and T-Mobile are teaming up with credit card companies to offer contact-less payment systems. (link)

Limitations of Square

Square is using a soft rollout so there are many limitations prospective users should be aware of.  Here are some of the major ones:

Transaction limits - they may be negotiable IF you can reach someone.  See complaints in Square Forum. [As of July those limits have been eliminated]

US sellers only (see FAQ post

Square reader delay - still very slow delivery of the card reader you need to get the discounted transaction rate.  Those who ordered on May 11th supposedly received notice of shipping in early September (see Squareup support post and post).  For those who have received the card reader, you'll need to insert a non-conductive washer so that the device will actually read on an iPhone 4.  See the Squareup support home page for latest status. 

Square is a scam?  There was some initial concerns about identity theft with Squareup earlier this year (see Square support post).

Late September update: Square support page says it is rapidly working through the backlog.   Upward of 50,000 readers are expected to be issued this year [no confirmation on this number yet]

Square only supports iOS and Android.  If you have a Blackberry, the encrypted ROAM audio plug-in has been introduced.

Here is a list of alternative mobile payment services.

Here is an interesting comparison on various credit card services for the small (occasional) business which Square is targeting.  This is the crux of the Square business model - no monthly fee but perhaps slightly higher transaction fee - net expense to the low volume business is lower.

Payment Structure

SquareUp has updated its rate structure. The proposed plan was a flat 2.9% without a transaction fee when the SquareUp beta began in December 2009. The announced rate starts as low as 2.75% plus a 15 cent transaction fee.

The current (April 2010) Square rate structure is the following:

Transaction Type SquareUp Others
Card Present (Swiped) Rate 2.75% + 15c 2.9% + 30c
Card Not Present (Keyed) Rate 3.5% + 15c 2.9% + 30c
Monthly Fee None $15-$25
Monthly Minimum None $25

The rates are attractive for the occasional seller who don't have to worry about a monthly or minimum fee.  The transaction fees are also competitive.

The Square application can be downloaded from the Apple App Store or Android Market

How to Use Square

Square offers the following product/service on the SquareUp:
