Near Field Communication (NFC) is a technology that has been around for many years, but has only recently begun to be used in consumer-facing devices, such as contactless payment. In this article, you will learn what NFC is, why it is often confused with RFID, and ten use cases for NFC technology, including its application in identity verification.
Near Field Communication (NFC) is a technology that enables devices to exchange information and data wirelessly over short distances. NFC allows devices to communicate with each other without physical contact, similar to Bluetooth.
NFC data exchange always involves two components. A device with an NFC chip, such as a smartphone, is the active transmitter - it establishes the connection, reads the transmitted data, and processes it. The passive part is the NFC chip itself.
When two devices are connected that are both active NFC transmitters, this is called active mode. When an active transmitter is connected to a passive transmitter, it is called passive mode.
NFC technology works in three modes, which can be further divided into active and passive modes: Peer-to-Peer (active), Reader/Writer (active) and Card Emulation (passive).
NFC tags are small chips that can be embedded in products or printed on labels. NFC tags contain information that can be read by an NFC-enabled device. The tags can be used to store a variety of information, such as Website URLs, contact information, or even small amounts of data.
The terms NFC and RFID are often used interchangeably. RFID (Radio Frequency Identification) is a technology that uses radio waves to communicate between devices, typically over a distance of a few meters.
The main difference between NFC and RFID is the range over which they can communicate. NFC is designed to communicate over short distances, while RFID has a longer range. NFC is also faster than RFID, as it can transmit data at a rate of 424 kbps, while RFID typically has a data transmission rate of 106 kbps.
NFC is widely used for contactless payments with systems such as Apple Pay and Android Pay. It is also used in some public transportation systems, such as the Oyster card in London. RFID is used in a variety of applications such as contactless key fobs, security systems and inventory management.

Feature | NFC (Near Field Communication) | RFID (Radio Frequency Identification) |
Communication Range |
Short distances (typically a few centimeters to about 10 centimeters) | Longer distances (typically a few meters to several meters) |
Data transmission speed | 424 kbit/s | Normally 106 kbit/s |
Applications |
- Contactless payment (e.g. Apple Pay, Android Pay) - Public transport systems (e.g., Oystercard in London) |
- Contactless key fobs - Security systems - Inventory management and logistics |
Usage | User-oriented, improves QR codes | Article oriented, improved printed barcodes |
As near field communication continues to evolve, new and innovative applications for NFC are likely to emerge. NFC technology is still in its infancy, but it has great potential. It could make many everyday things easier and more convenient.
Here are 5 reasons why we believe the use of NFC technology will continue to grow:
No technology is 100 percent secure against fraud. Even with NFC, data theft is theoretically possible. However, the person responsible would have to be in close proximity to the device. The short range of NFC is a clear advantage here, as it is very unlikely that a third party could access the data transmission. In particular, NFC offers increased security compared to data transmission via a WLAN connection, for example.
Ultimately, it depends on the context in which the function is used. For example, if you have an NFC-enabled credit or debit card that you occasionally use to pay without entering a PIN, it should not fall into unauthorized hands. If you plan to use your smartphone to make contactless payments via NFC, it is also advisable to use an antivirus program to prevent a possible virus on the smartphone from accessing the credit information stored in the NFC chip.
Near Field Communication is a versatile technology used in a wide range of applications, including retail, transportation, and banking. Here are 9 use cases:
The 10th use case of NFC technology is digital identity verification, and PXL Vision is an expert in this area. So let's take a closer look at this last use case.
In the context of identity verification, Near Field Communication can be used to wirelessly transmit information such as a person's name, date of birth or ID card number from an NFC-enabled ID card to a reader or smartphone. The reader or smartphone can then use this information to verify the person's identity. Passports or ID cards with an NFC chip can be used for online identity verification.
PXL Vision offers state-of-the-art verification capabilities via NFC. This innovative technology enables companies and organizations to verify identities in a secure and convenient way. Using NFC, customers can securely read and transmit biometric data and identification information, taking identity verification to a new level. PXL Vision leverages the reliability and security of NFC to help organizations implement efficient and trusted identity verification processes to best meet the needs of their customers.
