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
Ci sono molti usi dell'RFID. Pu\u00f2 essere utilizzato per coordinare e controllare l'accesso in diversi settori, come impianti industriali o fabbriche. In quanto tali, questi tag possono migliorare la produttivit\u00e0 dei processi industriali e ridurre gli sprechi monitorando l'utilizzo di materie prime e prodotti finiti.<\/p>\n\n\n\n
\u00c8 anche utile nella gestione e nel monitoraggio di asset, come camion commerciali o container nei porti o negli aeroporti. In questo modo si evitano perdite causate da furto o maltrattamento.<\/p>\n\n\n\n
Ad esempio, se un'azienda dispone di pi\u00f9 magazzini, pu\u00f2 localizzare le proprie merci ovunque vada semplicemente installando un lettore RFID all'ingresso di ogni magazzino. <\/p>\n\n\n\n
La tecnologia RFID pu\u00f2 essere utilizzata anche in molti altri settori come:<\/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
NFC ha diverse applicazioni, incluso il trasferimento di file tra smartphone, sistemi di pagamento, biglietti per i trasporti pubblici e carte di controllo dell'accesso ai contatti.<\/p>\n\n\n\n
Inoltre, i lettori NFC possono essere fissati in punti specifici per un rapido trasferimento dei dati. Un esempio di questo sono i bancomat, dove devi toccare la tua carta di credito su un lettore in modo che possa leggere alcune informazioni utili come numero di conto, data di scadenza e codice di sicurezza. <\/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 altro applicazione per tag 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 Tag NFC<\/a> pu\u00f2 anche essere utilizzato per avviare applicazioni o azioni specifiche sul dispositivo. Potresti averlo visto in azione in luoghi pubblici in cui ti viene chiesto di non usare il tuo telefono ma piuttosto di toccarlo contro un lettore. <\/p>\n\n\n\n Un esempio di questo \u00e8 Google Wallet, dove puoi effettuare acquisti online avvicinando il tuo cellulare a un lettore NFC. Questa azione consente a Google Wallet di trasferire i dati richiesti per completare la transazione.<\/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.
