RFID is a radio frequency identification technology that is gaining more space in the market. Helping in the movement of prostheses and contributing to the ease of use of buses and toll payment card, the technique is present in the Museum of Tomorrow, in Rio de Janeiro, and dispenses with the physical or visual contact.
Device built with Raspberry Pi control Internet of Things
the RFID is the evolution of bar code and with encrypted security, also promises to contribute to the Internet of Things. According to experts, the technology can help in the revolution of the devices everyday to connect everyone and everything.
Historical records indicate that the radio frequency identification was used in World War II to track approach of aircraft. According Felype Nery, an analyst for RFID, the technique is basically formed by a device that contains information that can be accessed quickly and intelligently through radio frequency. The system comprises a reader, an antenna and a label.
tags, or tags, used in the process can be identified at a distance of over 100 meters, depending on the RFID model, as is the case of devices installed in cars for automatic payment tolls. International standardization also contributes to the expansion and can be seen in the NFC feature available on mobile devices such as phones and tablets, and is considered an extension of the recognition by radio.

the technical applications are endless and, according to Nery, just “give wings to imagination.” The labels are quite used to taguear retail products, and have been seen also in athletes of the New York Marathon and prostheses. To move the implant, several labels are spread by the user’s body, depending on the movement you want to do, just move your hand in front of the specific tag.
Cost reduction
Despite restrictions near metal and water, the pattern identification has helped in economic crises. The technique, which has been falling in price, automates processes, almost zeroing time recognition products. According to Alexander Dal Forno, a specialist in RFID, companies that took weeks detecting goods can now do the same job in minutes.
“The technology allows you to find a box without having visual contact it, which makes it much faster process than using barcode. you can, for example, monitor the transport of goods of high value in real time and see if anything got out of the truck while traveling. the management is full ” says Dal Forno, who believes that the standard is here to stay.
to Claiton Colvero also expert in RFID, standardization of radio frequency identification and speed in reading “open up a world of opportunities. ” “In the near future it will be possible, for example, to see supermarkets equipped with RFID systems where the customer will the shopping cart for a portal reading and each product will be identified without making efforts to take and put everything in the cart” exemplifies Colvero.
at the Museum of Tomorrow, opened in late 2015 in Rio de Janeiro, an RFID card helps visitation. The card receives the aid of a similar operational assistant to the Siri Apple and Cortana Microsoft , and transmits the user information about space and works.
Security
The ID is also used in signal repeaters, locks and badges. Thus, data security can worry users. According to experts, you can use encryption to keep the danger away from the stored information. In addition, the tags carry a number where the actual information are stored in a database, as is already done with the bar code.
Internet of Things
Considered a technological revolution that connects items day to day on a global computer network, the Internet of Things is an evolution of RFID. To Felype Nery, an ideal application would be where the refrigerator items have labels and appliance knew by reading the tags you need to buy. “So the system would make a shopping list and would forward the request to the nearest supermarket,” Nery said.

According to Dal Forno, the Internet of Things started with radio frequency identification and evolved. “The technology comes with the concept of connecting things, equipment and people. It is a broader concept, with more intelligence in the tag, which passes information via Internet network, which opens up endless possibilities for new applications,” he says.

in January, the Campus Party 2016 , a Russian presented a system to control doors via a chip implanted RFID in the hands. According to the develop the resource proves that humans can also participate in the Internet age of Things and the equipment can also be used to check medical records, make payments and confirm the authentication of documents.
