Auto-ID is a tagging-system similar to the well-known barcodes but it's read without contact via radio-waves
The headquater of development for Auto-ID is the M.I.T. and its sister lab in the Univerity of Cambridge
Some Companies involved: Sun Microsystems, Coca-Cola, Intel, Kimberly-Clark, SAP, UPS, Wal-Mart Stores Inc., ...
The universal product code (U.P.C.) also known as barcode was developed in 1973. It was designed for 25 years, thus we its now out-dated. An other disadvantage of the barcode is, it must be rad manually
scenario: You walk into a shop, put your chocolate or whatever you want in you jacket, walk out of the door and you product get paid and the stock gets checked too. You don't have to wait for an old lady before you counting the coins or whatever .. and the it's easy for the shop to keep their products in stock. There're other advantages. We'll talk about them later.
Auto-ID works similar to the alarm-tags already used today, which activates an alarm if it doesn't get deactived after paying the product (or if you just don't pay at all). The concept it taken from a technology of the US-military developed in the 1940ies. The military-aircrafts got tagged, so it could be decided if an aircraft is a friend o foe.
the electronic product code (ePC) gets generated. This is an unique code for the product. The ePC gets saved on a smart-tag. A smart-tag is a microchip with an antenna and a small capacitor. This one gets sticked on the product for i.e. on a can, thus the can becomes unique.
And electro-magnetic field loads the capacitor. The load of the capacitor is enough energy for the microchip to send out a signal with its ePC. This one gets read and with a computer in the LAN or internet the ePC can be translated to usefull information stored in the product markup language (PML)
The ePC is similar to a barcode, but it's bigger (barcode: 12digits/circa; ePC: 96bits). The object name service (OSN) translate the ePC in an internet-adress for the PML-file for the product.
The physical markup language (PML) describes the parts of the product, its lengths, mass, et cetera. It can also describe transport vehicles, its containers and the items in the containers in a topdown model
The ePCs and the linked PMLs could be saved on CDs (i.e. weekly) as a backup) if the interner connection fails
Auto-ID in general may redefine the way things are made, bought and sold. Let's look on the different fields.
Everyone could be tracked via the tags on the items (i.e. pornography). But the tag-reader must be near the smart-tag. The detailed information (via PML) get also restricted, thus not everyone may get every infotmation. An solution (for paranoids) could be to destroy or throw away the smart-tags
A false smart-tag could send an other ePC-code. A possible solutions for shops is to only accept ePC-codes of products in stock.
One smart-tag still costs about 20 cents, but researches think development may lead to costs less a penny/tag
