What is NFC?
NFC is an acronym for Near Field Communication, which is close-range contactless communication between devices that can be used for payment, tickets, secure entry, keys, etc. There are three modes of operation that have been developed:
- The phone is used as a reader to read RFID tags and contactless smart cards, for example information on a poster
- The phone works in the same way as a contactless smart card and is used for payment, ticketing or access control
- The phone can exchange data with other phones or devices, for example a business card can be exchanged between two professionals
How does NFC Technology work?
NFC devices share data over a distance of a few centimetres through short-range high-frequency technology.The majority of NFC devices are smart phones or tablets; NFC technology builds on existing technology used with smart cards. The chip can be embedded in the device or it can be used through the memory card slot on some devices.
What are the advantages of NFC over Bluetooth technology?
They are both short-range communication techniques integrated into mobile phones, however NFC uses far less power than Bluetooth and can be used when the phone is switched off (handy if the users mobile phone battery dies). There is a lower risk of unwanted interception due to the shorter distance between the communicating devices.
NFC is compatible with existing RFID infrastructures. The user can connect quicker with NFC than Bluetooth technology because NFC connection is established automatically, where as with Bluetooth users have to initialise the connection themselves.
What are the advantages of NFC over barcode tickets on smart phones?
NFC can be used without the phone being switched on. So, for example if the users battery runs out before they have used their ticket it can still be read, unlike barcodes which need to be visible on the screen of the smart phone. Additionally, barcodes can be easily copied therefore making NFC chips more secure.
How is Rambus currently using NFC?
In conjunction with our RTD solution NFC can be used to purchase, download and use tickets all on one smart device.
What are the benefits of NFC?
- NFC technology is versatile and can be used in any industry
- Business can operate and respond in real time due to the speed of the technology
- Users do not need to be technically minded as the technology is automatic and connections do not need to be set up
- The technology supports secure applications
- There is no need to manufacture physical tickets therefore saving money
- The technology is interoperable globally, particularly useful when used for payment in various countries
- When used in a ticket or payment mode the user has the ability to view and load value using their smart phone
