Expandable Memory in Mobile Computing

One popular argument that Droid smartphone owners use to justify purchasing it against another phone is that it has the potential for expandable memory. A device with expandable memory might have very little storage but has space for an SD card to upgrade the capacity by 16, 32 or 64 GB depending on the size of the SD card.

Most commonly, though, they are used to direct people to a website in order to make purchases, gain information or, in some cases, get someone to open a webpage equipped with viruses. These viruses can compromise your security and allow hackers access to passwords and personal information like credit card numbers. How can you avoid this problem? Download a QR scanner that will allow you to preview the URL first, to make sure you trust the website it will direct you to.
