Since Visa’s investment with the mobile payment company, Square, we see that the two have announced a new version of the Square dongle that adds encryption and enhances security. Square has received much criticism in the past from Verifone, claiming that Square’s system is insecure and outdated.
Although Square has denied these allegations (who wouldn’t deny such allegations?), the company has introduced a new version of the Square reader that employs encryption, hinting that perhaps they did agree that security needed to be enhanced. Of course all this comes after Sony’s PlayStation Network gets hacked, is down for seven days, and has personal information of 70 million members stolen.
