Do smart cards and Rfid access cards use the same cocept/technology for functioning? Which is more effective? Is the GPS system anywhere connected to them?

Smart cards are used to store data, just like a flash drive or memory stick. There are two types of smart cards, "contact" , and "contactless".



The "contact" smart card requires that you place it into a card reader so the the reader can connect with the little gold contacts on the card. "Contactless" smart cards are capable of being read by the card reader from a short distance away - you don't need to actually insert them in a reader. You can both read and write data to both type of smart cards, but in general, the contact smart card can hold more data and can be read and written to quicker.



Most RFID access cards are simply an electronic number. When they are held in the vicinity of a proximity card reader, the number is sent from the card to the card reader and is passed along to a computer somewhere for processing. Most RFID access cards are "read-only", and only allow you read the number that is programmed on the card. However, there are a few types of RFID cards that are read/write and allow you to store a small amount of data on the card.



So, the RFID card and smart card operate on somewhat different principles, but both can do the same sorts of things.



As a general rule, the RFID card would be better for something like a card access control system on a door, because it would have a longer read range, but a contactless smart card could be used in this application as well.



A smart card is better suited to store larger amounts of data, so is most often used for things like medical records, biometric templates, etc.



GPS has nothing to do with either type of card. Neither a smart card nor a RFID card can read GPS signals. Because some smart cards can be equipped with a small microprocessor, I could see how a GPS interface might be possible in the future but I can't imagine why this would be needed.

Smart cards are a very different technology from RFID tags. Both are wireless, meaning they can communicate using radio like a cell phone, but contactless smart cards are far more advanced and secure.

smart cards have small but sophisticated computers inside them. They deliver the highest levels of computer security to protect your identity, privacy or financial information. Contactless smart card technology is suitable for uses such as identity credentials, passports and payment cards.

RFID (Radio Frequency IDentification) tags and labels are used mostly in manufacturing, shipping and object-related tracking. They have minimal built-in support for security and privacy. WalMart and others have been working to use RFID tags to replace bar codes on store-bought items to scan purchases and track inventory, for example.

Another important difference is how far away someone can read the cards or tags. Contactless smart card technology has a very limited read range of four inches or less to prevent tracking or eavesdropping. You can read RFID tags from much further away, however, up to thirty feet. This RFID feature lets you find items in a warehouse or identify railcars as they pass by, typical uses of RFID.

examine out RFID article on CNN the place the german company hacked RFID huge time . as far as a countrywide registry i'm unsure alot of people could choose for it even though it has alot of pluses . are you able to think of a Dr. in an ER waving a test over you to get your copmplete medical background and meds in a nanno 2nd . particular it may help decrease down unlawful;s and could make passports stressful to counterfeit - consistent with risk . If something we are shifting faraway from a funds financial equipment to a paperless financial equipment so as that made no experience and if we purely had paper are you able to think of all the individuals getting paid under the table and the counterfeiters and properly the record is infinite with all funds .
