Why is nfc better than rfid

Either they are active, meaning they have their own power source or they are passive. Passive tags have no own power source and have to be supplied with energy via an electromagnetic field produced by the reader. The reading range of LF and HF systems is usually only a few centimeters.

UHF tags, however, are often readable over distances of more than one meter. In peer-to-peer mode, it is also possible to transfer information between two NFC devices. Therefore, there are only short read range limitations. The main purpose is to identify and track automatically a tag attached to an object. NFC is a short-range high-frequency wireless technology that enables devices and smartphones to establish communication with each other by touching them together or bringing them into proximity.

Famoco aims at fitting the gap between very ruggedized devices and very flexible smartphones by offering the same features and the same level of security. The FX is a dedicated device to a chosen Android application and all devices are remotely manageable via an MDM platform. Next, the target modulates this power and sends it back to the initiator.

In comparison to an active mode, target in the passive mode restructures the amplitude of the original signal to send it back to the initiator. Despite both technologies appearing similar on the surface, there are 5 key differences between both technologies.. NFC technology operates on a reduced range, often called proximity. RFID, on the other hand, can read tags at distances going up to 10m, which makes it the best solution for vehicle identification and access.

NFC is capable of two-way communication, and as such can offer unique and complex solutions such as card emulation and peer-to-peer. This can limit its use cases and means that RFID tags are often better suited to environments where there are a lot of trackable components. An example of this could be asset management in a manufacturing facility or tracking fast moving vehicles. NFC technology stores and transmits multiple types of data. This makes NFC better suited to environments where payment details, membership, ticket etc.

This makes NFC a great solution for companies that are on a tight budget, but still, want to employ a high-quality solution. As you can see from the differences between both technologies, each holds unique properties that are demonstrated in NFC and RFID access control.
