NFC technology & its advantages

What is NFC?

NFC means "Near Field Communication" and has been on the market for a long time. It refers to contactless data transmission that makes use of radio frequency identification (RFID) technology. The globally standardized frequency is 13.56 MHz. Transmission ranges of around five to ten centimeters are possible.
The main difference to the QR code is that NFC technology uses mobile devices such as cell phones, tablets and notebooks to exchange data. This enables numerous new applications, including in the consumer sector, such as intelligent posters, payment systems and interactive marketing campaigns.

In principle, there are three different modes in the NFC sector:

The smartphone takes on the function of a contactless card. For example, you can use your smartphone to open hotel room doors or gain access to your company, including time recording. The smartphone also replaces the credit card for all payment solutions. The smartphone is placed on the reader at the checkout and the financial transaction is carried out
Possible applications include smart-POSTER. In this application, you hold your smartphone to the chip integrated in the poster, a mobile website opens and you can directly purchase a ticket for the advertised concert or make a donation. The smartphone is therefore the reader for the chip for all these applications.
In this mode, two smartphones or tablets communicate with each other. This allows data, contacts and images to be transferred from one mobile device to another.

How is NFC used?

Passive NFC tags can be used to tag almost any object, giving it "intelligence" and access to the Internet. "Make the unconnected connected" is becoming a reality. All everyday objects are beginning to communicate with each other via the Internet thanks to NFC technology. Only NFC technology makes IoT, mobile payment and smart HOME possible. With NFC-compatible end devices (cell phones, tablets and notebooks with an integrated NFC interface), the data stored on the NFC tag can be read quickly and easily and further actions can be triggered. The NFC chip technologies can be integrated into all product groups in the smart-TEC portfolio.

Differences between NFC and QR code

NFC interface is already integrated in almost all new mobile phones

NFC is standardized worldwide and can be used extensively - industry,

Logistics, marketing, automotive sector, etc.

No special app is required

International transmission standard is at a frequency of 13.56 MHz and is based on the ISO14443 or ISO15693 standard

Distance up to a maximum of 5 cm and fast connection establishment

Each NFC chip has a globally unique identification number. This makes every product unique, traceable and original

Invisible integration into existing design, as no line of sight to the smartphone is required

Almost 100% first read rate

Data on the chip can be added, read and changed at any time

A special app is required on the smartphone to read a QR code

QR code can visually devalue the customer layout

Code is susceptible to soiling, which dramatically reduces the first read rate

QR code data cannot be changed = static, unchangeable data

Long website URLs generate a very large QR code and poor reading results
