These days, a person, an animal, or an object can be identified in a state of the art manner using a wireless non-contact technology through radio-frequency identification or RFID. It is in this frequency that information is transferred and interpreted by a RFID reader. A pet with RFID tag can be located with ease using the RFID scanner. You can also view the information stored in the tag through the RFID reader.
Uses of RFID The RFID technology has been used mainly in different industries since tracking and identification play a huge role in managing inventories and assets. For example, RFID chips are used in production of electronic devices like mobile phones, TVs, PCs and more since it is easier for workers to track the progress of the objects when they can simply scan the items during production. Meanwhile, farmers also rely on the technology to manage their farm animals effectively. By inserting tags in their livestock, they can identify and track each animal with ease. To give a concrete example, farmers insert RFID tags to their farm animals. Using the technology, they can easily locate the animals ready for breeding since the tag contains information of the animal.
RFID technology is now also adapted in touch free payment systems. Mobile phones equipped with RFID chip can be used to pay for items electronically while the device can also be used as an RFID reader. The chip inside these devices contains your bank account information so you can use your phone to pay for items in the same manner as you would use your credit card. Since the tag can store sensitive details, enhanced security features are added to secure your information. You need to input your password or pin before releasing any valuable information.
RFID Technology Today Nowadays, you can use the technology even to track or identify minimum number of items or in a small scale at a fraction of the cost. The technology is very affordable these days that you can purchase a set for a couple of dollars. Of course sophisticated RFID systems which can contain more data and can be read using advanced technology are more expensive. You can now use RFID to tag your pets so you can easily locate them if in case they got out of your house. This is ideal for pets which have the tendency to stray because a RFID tag and a reader such as a RFID USB reader can trace and identify the animal with ease. Google Nexus 7 Nfc
Smart phones today are no longer simple devices for communication; these state of the art phones are now used for commerce too. Experts predict that phones will be used for other purposes other than allowing two or more people to talk. It is because current phones are now equipped with technology that could read and interpret information from other devices. Today, some smart phones can be used to pay for our bills, gather information from other devices, and even socialize with other people. This is happening because today?s phones and tablets are now equipped with NFC technology so owners can use their devices other than sending SMS or calls.
What is NFC and how it Works NFC which stands for Near Field Communication is a type of communication or exchange of data that relies on electromagnetic radio fields. The technology is akin to Bluetooth or Wi-Fi since NFC also allows a user to acquire or transfer data wirelessly. It can also be likened to RFID since it is also a wireless transfer of communication. However NFC devices as to be within proximity in order to allow exchange of information.
Sharing or acquiring of data in NFC is possible in two ways. Exchange can either be passive or active.
Passive enabled devices only store information for other NFC enabled devices to read. For instance, magazines with tags containing additional readings which are only accessible to smart phone users with NFC scanners.
On the other hand, active NFC is present in smart phones. The devices have the ability to extract and interpret data from passive NFC. In the scenario presented above, the active device with NFC is the smart phone used to scan the barcode in the magazine. What?s great about devices with active NFC system is that you can also share the acquired information. You can even alter the information if the programming allows you to do so.
