Credit card USB flash drives have grown tremendously in popularity for marketing campaigns and promotional giveaways. Sleek and customizable, a credit card drive offers significantly more space to print a logo or mission statement on the drive. Of course, swivel and standard drives are still popular, customizable and compact, but we have noticed a shift towards the card drives. Capable of the same amount of storage, credit cards drives can be any color, they can also be a silver colored metal which gives a professional shine and modern edge. Custom USB drives are most popular among marketing firms, photographers, and of course, software technology companies. The look and feel of the USB drive is especially important for the former two applications. The exterior of the drive often times represents the contents, so it needs to be appealing enough for the recipient to take the extra step and plug it in.
