USB a promotional item
USB means Universal Serial Bus, it is not any kind of object but an industry standard which defines connection of cables, connectors and protocols and portable devices? with Computer, or such high gadget platforms like Smart phones. With its increase in general use the items started to be recognised as USB Devices derived after its use and system standard.
USB is very simple to be a promotional item, but as it is used in daily life specially in this computer age where every one has a dongle in their pocket to connect to web at any time, this dongle is also a kind of USB device, so using it as a promotional item seems to be much sensible. It is not necessary that a USB is to be a system device or portable hardware, but also common electronic gadgets like Calculators, shredder and opener, and card reader can be categorised under USB, so while using them as a promotional item it becomes very useful and proves beneficial to use them as a promotional product.
