The primary difference between RFID and NFC is that NFC works only with short distances (usually less than 10 cm), and it can be powered by capacitive energy transfer. <\/p>\n\n\n\n
On the other hand, RFID uses the frequency of 125 kHz\/13.56 MHz and requires a power source (battery or induction coil). It offers a maximum range of 100 meters.<\/p>\n\n\n\n
Besides these differences, the technologies are pretty similar. This article gives an in-depth comparison between NFC and RFID.<\/p>\n\n\n\n
RFID (Radio Frequency Identification) is a wireless non-contact technology that uses electromagnetic fields to transfer data from the Tag (transponder) to the Reader (interrogator).<\/p>\n\n\n\n
The two main components of an RFID system are a tag and a reader device, each having an antenna. The transmission medium is the air interface.<\/p>\n\n\n\n
It works at very high frequencies (125 kHz\/13.56 MHz). As such, it allows large amounts of data to be transferred quickly between two transponders or between a transponder and a reader. <\/p>\n\n\n\n
Il existe de nombreuses utilisations de la RFID. Il peut \u00eatre utilis\u00e9 pour coordonner et contr\u00f4ler l'acc\u00e8s dans diff\u00e9rents secteurs, tels que les installations industrielles ou les usines. Ainsi, ces balises peuvent am\u00e9liorer la productivit\u00e9 des processus industriels et r\u00e9duire les d\u00e9chets en surveillant l'utilisation des mati\u00e8res premi\u00e8res et des produits finis.<\/p>\n\n\n\n
Il est \u00e9galement utile pour g\u00e9rer et surveiller les actifs, tels que les camions commerciaux ou les conteneurs dans les ports ou les a\u00e9roports. De cette fa\u00e7on, vous \u00e9vitez les pertes caus\u00e9es par un vol ou une mauvaise manipulation.<\/p>\n\n\n\n
Par exemple, si une entreprise poss\u00e8de plusieurs entrep\u00f4ts, elle peut localiser ses marchandises o\u00f9 qu'elles aillent en installant simplement un lecteur RFID \u00e0 l'entr\u00e9e de chaque entrep\u00f4t. <\/p>\n\n\n\n
La technologie RFID peut \u00e9galement \u00eatre utilis\u00e9e dans de nombreux autres domaines tels que :<\/p>\n\n\n\n
NFC (Near field communication) is a wireless communication technology that allows two electronic devices closely placed (up to 4 cm) to establish communication and exchange data. <\/p>\n\n\n\n
It is related to RFID but it works at lower frequencies (13.56 MHz). They allow large amounts of data to be transferred quickly between two transponders almost simultaneously.<\/p>\n\n\n\n
NFC is comparable to Bluetooth, Infrared (IR), and Wireless LAN standards. Although each of these technologies has its protocol standard, they all establish communication using electromagnetic fields.<\/p>\n\n\n\n
This technology requires short-range, so it is used to create wireless connections between small portable devices such as mobile phones or tablets.<\/p>\n\n\n\n
An NFC tag contains information that different applications can access – usually through an NFC Service ID assigned by the manufacturer, depending on what service this tag will offer. <\/p>\n\n\n\n
They have an NFC chip and an antenna embedded in a label or printed directly on a surface. The tag can be read from up to 20 cm (7.9 in) away by an active NFC device such as modern smartphones.<\/p>\n\n\n\n
Le NFC a plusieurs applications, notamment le transfert de fichiers entre smartphones, les syst\u00e8mes de paiement, la billetterie des transports en commun et les cartes de contr\u00f4le d'acc\u00e8s des contacts.<\/p>\n\n\n\n
De plus, les lecteurs NFC peuvent \u00eatre fix\u00e9s \u00e0 des endroits sp\u00e9cifiques pour un transfert de donn\u00e9es rapide. Un exemple de ceci est les guichets automatiques, o\u00f9 vous devez taper votre carte de cr\u00e9dit sur un lecteur afin qu'il puisse lire des informations utiles telles que le num\u00e9ro de compte, la date d'expiration et le code de s\u00e9curit\u00e9. <\/p>\n\n\n\n
This way, making an online purchase is secure since no one will be able to steal your password or bank account during the payment – unless they get access to that NFC device (ATM) which stores your banking details.<\/p>\n\n\n\n
Un autre application pour tags NFC<\/a> is in advertising. A lot of companies want their message out there but not everyone has enough money to buy television ads. These companies create special items containing the company’s logo with an NFC tag embedded inside them – so when someone walks nearby with an NFC-enabled mobile, the tag will be scanned and a message pops up.<\/p>\n\n\n\n Balises NFC<\/a> peut \u00e9galement \u00eatre utilis\u00e9 pour lancer des applications ou des actions sp\u00e9cifiques sur votre appareil. Vous avez peut-\u00eatre vu cela en action dans des lieux publics o\u00f9 l'on vous demande de ne pas utiliser votre t\u00e9l\u00e9phone mais plut\u00f4t de le taper contre un lecteur. <\/p>\n\n\n\n Un exemple de ceci est Google Wallet o\u00f9 vous pouvez effectuer des achats en ligne en pla\u00e7ant votre mobile contre un lecteur NFC. Cette action lance Google Wallet dans le transfert des donn\u00e9es requises pour terminer la transaction.<\/p>\n\n\n\n These technologies work on the same principle: sending and receiving data without any physical contact. While their speeds are very close, RFID is faster for a wide read range while NFC works in a smaller area.<\/p>\n\n\n\n Both RFID and NFC do not require a direct line of sight. As such, you can read the tags from whichever angle you find convenient. This feature makes the tag more reliable and faster compared to barcodes. <\/p>\n\n\n\n However, there are a few differences between RFID and NFC, including:<\/p>\n\n\n\n Both NFC and RFID are highly reliable. However, you should define your needs before you settle for one. If you need one for identification and access control, then we recommend RFID. If you need one for communication and data exchange, then you should choose NFC. <\/p>\n\n\n\n The primary difference between RFID and NFC is that NFC works only with short distances (usually less than 10 cm), and it can be powered by capacitive energy transfer.
