teChnicAl (continued from page 56) be read, or swiped in the special slot. Lookatyourcardandseeifthereisa small icon that looks like an echo. See fgure two. Figure Two This type card has security issues, because they can be scanned while still in your pocket or purse without your knowledge. More than likely a thief would use a hand held mobile reader and move close to you in a crowded area. Metal Sleeves are available to slide over your card when not in use, but tin foil works just as good. Many times you can actually see the small bulge on dent on the card where the chip is. If you want to take it a step further, just drill a small hole straight through the chip. You can still use the card in the normal way. So, why bother with RFID stuff when it looks like Barcode Readers do the same thing? Barcode items have to be scanned within a few inches, one at a time, like at a supermarket checkout counter. RFID tagged inventory can be read all at once from a distance, which is determined by the Reader size and frequency, also whether the tags are passive or active. Barcode is normally limited to only generic information, while Tagged items are capable of containing much more information, typically 2000 Bytes, which can include date of manufacture to help with inventory turn, or expiration dates for product freshness like products with batteries for example. The RFID software actually interprets the tag code to do this. Another RFID example would be a Forklift operator shipping or receiving a pallet full of items that already have tags, or perhaps just the shipping pallet has the tag. As the driver passes in or out of the building, a reader at the entrance would read the entire contents of the pallet remotely all at once, and put it in or out of inventory. Short range Readers work at low KHZ frequency, at about 4 inches, similar to Barcode, 58 and would be used for checking Access control cards for example. High MHZ frequency range now work from 3-50 feet and long range UHF originally from 3-15 feet is now up to 100+ feet. ManyPassportsnowhaveRFIDchips, and can contain biometric information like a photo or fngerprint, even your travel history. Metal sleeves should be usedhereaswellunlessthePassport has a radio shield inserted between the passport's cover and frst page. The Department of Homeland Security has been using RFID for checking Airport luggage from point of entry to destination at certain Airports, as well as checking immigration RFID work cards. One interesting application is that Casinos are now producing playing chips with built in RFID chips because of recent counterfeiting. Actually I could fll the next two pages with more examples of this exploding Old-New technology. There are so many different kinds of Tags and Readers that I would need a lot of space to list them all. Jump on the internetandGoogleRFIDTagsorReaders, and you'll fnd an enormous amount of Tag and Reader information. To get data onto the RFID tags, there are two ways it is done. Do it yourself, or let the RFID Tag supplier do it. The vast majority of RFID users count on their Tag supplier to handle that, as well as supplying the necessary software. In addition to the availability of a large assortment of ready made tags, shipping labels can also be printed with RFID chip inlays built in. You most likely have seen many retail items with an ElectronicProductCode(EPC)label. These smart labels are produced by embedding RFID chip inlays inside the label material, and then printing bar code and other visible information on the surface of the label. If you want to print your own RFID tag shipping labels, you can purchase an RFID printer starting around $1000 and up….(and Way up). Aside from inventory and theft control, I thought about Apartment Houses, GatedCommunities,andcontrolled parking facilities where management has much more security concerns with access control. One particular security International Door & Operator Industry™ problem that management complained about was that valid occupants (or employees) would buy additional remotes and give them to friends or relatives to gain unauthorized access. An RFID systemlikeE-ZPASSwouldstopthatpractice if one unit per car was authorized. The occupants wouldn't have easy access to additional programmed units. IenvisionotherpossibleGarageDoor applications especially for commercial applications. Keypads are great unless the code is given out to unauthorized personnel. RFID readers would stop that as well. Security companies have been using this technology for 30+ years. Actually, you might not even need an outside reader; the reader could be inside the garage or built into the opener, which opens the door for even more possibilities. Newer hybrid tags, (semi-active), are now being developed to collect and transmit information from other devices. This is hot area of development within the RFID world because it changes tags from being just an identifer, to a communication device from sensors. (water, humidity, temperature, orientation, etc). (…maybe photocells) This exploding technology may never be incorporated into our products, but it's sitting there waiting for us to explore. Near feld communication (NFC) is a setofstandardsforSmartPhonesand similar devices to establish Radio Communication with each other by touching them together or bringing them into close proximity, usually about an inch,whichmeansyourSmartPhone can be a Reader of RFID tags. RFID technology will be used in new and innovative ways, and many of the best uses haven't even been dreamed up yet. I no longer have inventory concerns, so I'd better get busy and have a chipputinFidoandGrandPopwhile I'm thinking about it. I might also put a GPSlocatorcollarontheFamilyHamster who keeps escaping from his cage and hiding in different places in the house. In the past, Fido the Beagle was placed in service, but won't be needed much longer.
