With the holiday shopping season just about over, the overall sales numbers are starting to come in, and a positive trend is emerging.

The Los Angeles Times cited a MasterCard SpendingPulse report that found sales in holiday-related categories like apparel, electronics and jewelry increased 2.3 percent. This numbers come from following transactions recorded from November 1 through December 24.  To take it a step further, the overall spending numbers increased 3.5 percent when compared to the numbers from last year.

Sarah Quinlan, the senior vice president of market insights for MasterCard Advisors, was interviewed in the piece and pointed toward e-commerce as a major component of the increased sales numbers.

"One clear bright spot is that many consumers who were stuck indoors turned to online shopping to check items off their list," Quinlan told the news source.

The research also shows that on Christmas Day alone, online sales surged 16.5 percent year over year. On top of that, visits from mobile devices made up a record 48 percent of all online traffic. By comparison, last year, e-commerce from mobile devices was only responsible for 28.3 percent.

Amazon is reporting that it had its best holiday season on record. As an example, 36.8 million items were ordered worldwide during Cyber Monday which breaks down to 426 items per second.

With this increase in sales, organizations need to make sure their point of sale software system is able to handle improved numbers, especially if this trend continues going forward.
