RFID Chips are becoming ubiquitous. Already most major retailers insist that all pallets arriving into their distribution centers are tagged with the chip. This is all poised to potentially
save you money and
protect you from counterfeitingSo what is the deal here? What are they, and how will it affect your daily life?
RFID , or Radio Frequency
IDentification, is really like a very small radio station, that only plays one song over and over. In this case the song is the unique Identifier for the product. This allows the radio listener, or scanner, to pick up the location of the device. Think of it as a UPC on steroids.
UPCs revolutionized your grocery shopping experience.
Remember when every single item had to hand entered by price? Those cashiers were really amazing, but there were big issue, as stores got
bigger with more selection, it became impossible to remember every price in the store so they relied on the price sticker (when is the last time you saw every can of Corn having a price sticker!). Well price stickers can come off or be changed, Price check on aisle one! On top of that the only way a store new what was in stock was to physically count Everything!
With the UPC and the bar graph, scanning was made available then eventually affordable. This dramatically cut down checkout time, and real-time inventory levels were available leading to less stock-out issues.
RFID is the next level. This doesn't need to be scanned. As long as the reader is close enough it can pick it up. Imagine pushing your grocery cart
thought the check out line, up to the register and they already have the pricing for you!
The limiting factor has been cost. You can't tag a dollar item with a dollar tag! UPC just relied on a printing surface. But like the laser scanner, volume is king and the chips are getting very cheap.
This has lead to new uses such as
Contact less Credit Cards -
RFID is what powers the
AmEx Blue card and other "contact only" cards. Also the pet finder chips are based on the same technologies. Goods can be authenticated using the technology, so you can be sure to get a "real" version of the item. In addition this is being used to reduce theft at retail, which is a multi-billion dollar issue and
costs you money in the form of higher prices.
