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
Hay muchos usos de RFID. Se puede utilizar para coordinar y controlar el acceso en diferentes sectores, como plantas industriales o f\u00e1bricas. Como tales, estas etiquetas pueden mejorar la productividad de los procesos industriales y reducir los desechos al monitorear el uso de materias primas y productos terminados.<\/p>\n\n\n\n
Tambi\u00e9n es \u00fatil para administrar y monitorear activos, como camiones comerciales o contenedores en puertos o aeropuertos. De esta forma, evita p\u00e9rdidas por robo o mal manejo.<\/p>\n\n\n\n
Por ejemplo, si una empresa tiene varios almacenes, puede localizar su mercanc\u00eda all\u00e1 donde vaya simplemente instalando un lector RFID en la entrada de cada almac\u00e9n. <\/p>\n\n\n\n
La tecnolog\u00eda RFID tambi\u00e9n se puede utilizar en muchas otras \u00e1reas, tales como:<\/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 tiene varias aplicaciones, incluida la transferencia de archivos entre tel\u00e9fonos inteligentes, sistemas de pago, emisi\u00f3n de boletos de transporte p\u00fablico y tarjetas de control de acceso de contacto.<\/p>\n\n\n\n
Adem\u00e1s, los lectores NFC se pueden fijar en lugares espec\u00edficos para una transferencia de datos r\u00e1pida. Un ejemplo de esto son los cajeros autom\u00e1ticos, donde debe tocar su tarjeta de cr\u00e9dito en un lector para que pueda leer informaci\u00f3n \u00fatil, como el n\u00famero de cuenta, la fecha de vencimiento y el c\u00f3digo de seguridad. <\/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
Otro solicitud de etiquetas 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 Etiquetas NFC<\/a> tambi\u00e9n se puede utilizar para iniciar aplicaciones o acciones espec\u00edficas en su dispositivo. Es posible que haya visto esto en acci\u00f3n en lugares p\u00fablicos donde se le pide que no use su tel\u00e9fono sino que lo toque contra un lector. <\/p>\n\n\n\n Un ejemplo de esto es Google Wallet, donde puede realizar compras en l\u00ednea tocando su tel\u00e9fono m\u00f3vil contra un lector NFC. Esta acci\u00f3n inicia Google Wallet para transferir los datos necesarios para completar la transacci\u00f3n.<\/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. On the other hand, RFID uses the frequency of 125 kHz\/13.56 MHz and requires a power source (battery or induction coil).
