Founded by Twitter’s Jack Dorsey Square is a mobile payment system. It consists of two apps: Square Wallet for buyers and Square Register for sellers.

Incredibly easy to setup both apps co-exist as buyers can use the wallet app to purchse at merchants where they have the register app, but this is not an impediment as huge sellers like Starbucks have already adopted the mobile payment platform.

Square Wallet: it is as easy as downloading the app into your smartphone, linking your credit or debit card, and start paying.

The wallet’s cool features include: 1. pay using your phone not your plastic credit cards, 2. pay using your name not your phone!, 3. find cool stores and merchants where you are, 4. get and send gift cards by email or sms!

Square Register: with a few clicks you can download the register app into your smartphone or tablet. Setting it up is fast and free and in no time you can start getting payed with credit cards. You will receive a free “card reader” delivered to your address, but in the meantime you can just enter credit card data manually and charge any amounts immediately.

The register’s cool features include: 1. the free card reader which is small and connects to your mobile device through the earphone plug, 2. there are no expenses and the fee is only 2.75% on every sale, if you don’t sell you don’t pay anything!, 3. a “cash register” section where you can preset products and services so you can charge your customers with a touch, 4. you can list your business in their merchant listings that clients use to find you when they are close to your area.
