Radio Frequency Identification (RFID) tags, or microchips, are used in everything from clothing labels to passports in order to identify and track the movement of goods.

Would you willingly submit to this futuristic technology, or does the whole thing scream "privacy-invading conspiracy"?
In this week's Whaddyareckon? we get your thoughts on human microchipping.
