MicroSDOwners of relatively new cell phones might have noticed a slot that says "microSD" on the side. These are tiny memory cards that store between 2 and 16 GB of music, photos, video and files, and with an inexpensive adapter, they can be easily transferred between a phone, computer and even some TVs. Preload a microSD card with a promotional video or materials, and recipients will use it far more than they would a USB flash memory drive. The smallest ones cost about $10.
