Square device for electronic fund transfer


The square is a small plug in your mobile phones that allows you to receive credit card payments. JACK DORSEY, the co-inventor of Twitter, invents this device and it got the name SQUARE because of its shape. The story behind the creation of this device is also very interesting. It all begins in 2009 when Dorsey’s friend James McKelvey was not able to sell glass faucets and fittings, cost 2000$, because he could not accept credit cards. This event leads to the creation of one entire firm called as Square, Inc. Jack Dorsey and Jim McKelvey founded this company in 2009 based in San Francisco, California and it launched its first app in 2010.


    Jack DorseyCurrently SQUARE provides free SQUARE CARDS for free. You can download SQUARE app for free from App store or Google Play store. Now you will be wondering if they provide everything for free what the source of income is for the company. So, the answer is they charge you 2.75% on every credit transaction. This rate, 2.75%, is higher than the conventional rates charged by credit card companies but SQUARE’s manufactures claim that they never charge anything other than 2.75% which is charged by Credit Cards Company and consumers never came to know about that. In addition to that there is no monthly fee or set-up fee. It is considered as a very useful App for entrepreneurs. In very short time SQUARE become very popular as a result of that, in August 2011 Starbucks (an American global coffee company and coffee-house chain based in Seattle, Washington) announced that it would use SQUARE for its transactions. Starbucks also invested $25 Million in Square.


The original card reader of SQUARE consisted of simple read head which is directly wired with 3.5mm audio jack. Through this jack only unencrypted, analogue card information is fed to the smartphones. Smartphones with the help of already downloaded App do the amplification and digitization. Which ends in the electronic fund transfer using credit cards.

Square currently uses very strong encryption technology for its devices. Its Cryptography key is at least 2048 bit long and cannot be cracked easily. It reads information on a credit card when it is swiped. The information is not stored on the device but is encrypted and sent over secure channels to banks. It basically makes any mobile phone a cash register for accepting card payments. As a payer, you receive a receipt via email that can be instantly accessed securely online. You can also use a text message to authorize payment in real time. SQUARE’s technology is Payment Card Industry Data Security Standard (PCI DSS) compliant and Verisign (an American company based in Reston, Virginia, United States that operates a diverse array of network infrastructure) certified.
