Nfc Reader Android Info 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. Some brands would now allow users to pay for their bills, read information, 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 Near Field Communication or NFC is a system that allows you to communicate or gather data using the electromagnetic radio fields emitted by NFC enabled devices. The system is similar to Bluetooth or Wi-Fi since it allows transfer or exchange of data wirelessly. RFID is another system that is close to what NFC does but the latter must be close to other NFC devices for the technology to work.

NFC is available in two forms: passive and active NFC.

Passive devices like an NFC tag contain data which other devices can read. For example, a magazine with a tag may contain additional information which you may read if you scan the code using your NFC enabled device.

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 example above, the active device is the NFC enabled smart phones. 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. Radio Frequency Identification Tags

NFC Technology on Android Devices Android has confirmed that it will be embracing the NFC technology because it sees the technology as something useful especially in commerce and security.

Currently, there are brands equipped with NFC system. Samsung, LG, HTC, and Sony have fitted their phones with NFC technology so users can simply gather and share data through electromagnetic radio field. Other function of NFC on android includes interpreting data from a passive tag. Downloading an android NFC reader app from the Google Play Store will also transform your phone into a scanner. Simply download and install the app and start using your phone to scan passive codes and share the information to other NFC device users.

Nowadays, it is possible to indentify or track a person, animal, or object using a state of the art technology of radio frequency identification or RFID. The system relies on the radio frequency electromagnetic fields to transfer data needed for identification or tracking. A person with a RFID chip for instance can be identified or traced since the chip contains the information of the person which is automatically read by a RFID reader.

Uses of RFID Right now, RFID technology has been applied to numerous industries since tracking and identification are important actions in controlling inventories and assets of the businesses. 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 can now easily identify their farm animals individually because each tag can be written or stored with specific information. For instance, if a farmer maintains hundreds of cows he can immediately identify his prized bull by simply using the RFID scanner to scan the animalÕs location.

Meanwhile, individuals can now pay for their items without using actual money or even credit card. Device such as mobile phones equipped with RFID tags can transfer payment wirelessly. It is now possible to turn ordinary mobile phones into devices capable of transferring payment and also as RFID reader. The chip is wired directly to your bank information so you can use your phone to pay for stuff so you wonÕt have to carry money or credit card anymore. Of course, since the RFID chip contains your sensitive information, security features are added to the system for safe transactions.

RFID Technology Today Nowadays, you can use RFID to track or identify personal belongings. This is because the technology is made affordable for everyone to use. You can even purchase a RFID tag and a scanner for a couple of dollars in electronic shops.
