Nfc in mobile | NFC range, security, and label: We all have seen NFC in Mobile phones or in smart posters or smart pay (contactless payment) but never used it intentionally instead we use Bluetooth or wifi share. So what is NFC? , What’re its ranges, frequency band? , What is the use of NFC in Mobile phones?
What is NFC?
Near field communication (NFC) is a communication protocol where two devices interact and share some data and information with each other when they are near to each other. NFC RANGE is just about 1.6 inches (4 cm) That’s why it is used in contactless payment.
What is NFC based on?
NFC is based on Radio frequency identification technology (RFID) which access the information between two NFC enabled devices and even power the other devices.NFC basically works when two near devices create electromagnetic induction between two loop antennas and share their data.
What is NFC range, frequency band and sharing speed?
NFC DTR: 104-425 kilobits per second (kbps)
NFC frequency band: Nfc works with the frequency of 13.56MHz
NFC range: 1.6 inches ( 4cm ).
What is the use of NFC in Mobile phones?
NFC in Mobile can be used in three modes:
1. NFC secure payment
NFC enabled devices such as smartphones act like smart cards, allowing users to perform money transactions such as tap payment or buy tickets.
2. NFC reader or writer
NFC enabled devices can be even to read information that is stored on inexpensive NFC tags embedded in NFC labels or smart posters.
3. NFC share
NFC share enables NFC enabled devices to communicate with each other to exchange information in a unique way.
NFC security issue?
Even with very low range NFC is still not full proof secure. Relay attacks or Man-in-the-middle attacks can be it done to read the data. NFC still has some security issue to be fixed.
