Smart phones today are more than just devices for talking. Gone are the days when we only rely on our mobile phones to communicate with our families or friends. 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
NFC which stands for Near Field Communication is a type of communication or exchange of data that relies on electromagnetic radio fields. This innovation can be likened to Bluetooth or Wi-Fi. NFC allows exchange of data without use of wires. It is also similar to RFID but with the exception that NFC devices has to be within close proximity to each other to work.

What is RFID Technology and what are its Uses?

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.

The other type is active which are electronic devices which can extract information from a passive NFC. In the example given earlier, the active NFC system is available in the smart phone. The phone is equipped with a system that can acquire data from the passive 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.

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. It is now possible to read passive tags using your phone. The NFC equipped phones now work as a scanner. By downloading an android NFC reader, you can turn your phone into an NFC tag reader so you will be able to acquire and share information stored in passive tags.

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. This technology uses radio frequency electromagnetic fields to transfer data for identification or tracking purposes. 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
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 tags are used in mobile phone production. Workers can easily follow the progress of the devices by simply scanning the items. RFID technology is also used in livestock because tracking farm animals is important to maintain quality control inside the farm. Even if a farmer has hundreds of cows in his farm, he can identify his prized cow by merely scanning the RFID chip embedded in the animal.

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. You can now use your mobile phones to pay for your groceries as long as your phone has RFID tag. You can even use your phone as an RFID reader if you want to information about a certain item in the store. 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. 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.
