Analysis: Much as I hate to spoil the suspense, we have to begin sorting out truth from fiction before it becomes too confusing to tell them apart.
The device pictured above is, in fact, one example of a biochip (also known as a microchip implant, ID chip, RFID chip, etc.) — a tiny, implantable wireless transponder which emits a weak radio signal in the presence of a scanner and can transmit small amounts of information (e.g., identification numbers) to a receiver. It is indeed about the size of a grain of rice.
That is not what the text of the slide show is describing, however. Intentionally or not, the author is confusing biochips (implantable microchips) with a different kind of microchip designed to be embedded in so-called "smart cards" to store personal information (e.g., your checking account balance). The smart card was conceived as an alternative to both paper money and ordinary credit cards, but we're still a ways off from the day it will replace them.
Main point: The technology pictured above isn't the same as the technology described above.
