Mike Langberg makes five big technology predictions for life ten years from now in 2012. Most interesting is his prediction regarding RFID:
Stores without doors will rely on RFID, or radio-frequency identification, tags to keep track of inventory and payment. These tiny semiconductors communicate a small amount of information, such as a product serial number, when queried by inexpensive transmitter/receivers. Only recently selling for several dollars, RFID chips should cost only a few cents next year and will be smaller than a grain of rice.
In 2012, RFID chips will sell for less than a penny and be printed onto packaging and price tags — the beginning of the end for cash registers. You walk into a store, put what you want in a bag and walk out the door. An RFID transmitter/receiver in the entryway instantly totals up your purchases and makes a deduction from the RFID credit card in your wallet. If nothing else, RFID could have spared Winona Ryder her recent and very embarrassing shoplifting arrest.
