A small slice is pasted into the poster and programmed in a specific way. When the user places the mobile on the poster, the data is uploaded to the mobile automatically.
This method can also be used to create smart personal cards. So, if you want to share your data with others, all you must do is put your phone on the smart card, and the data will be automatically transferred to the phone.

NFC stands for Near Field Communication. It is a short-range wireless communication technology that enables the exchange of data between devices that are in close proximity to each other, typically within a few centimetres. NFC operates on the principles of electromagnetic radio field communication, allowing compatible devices to establish communication by simply bringing them close together or tapping them against each other.

NFC technology is commonly used in various applications, including contactless payments, mobile ticketing, access control systems, data transfer between devices, and more. It is often found in smartphones, tablets, and other portable devices, as well as in certain cards and tags.

One of the most well-known uses of NFC is for mobile payments. By linking a smartphone or other NFC-enabled device to a payment method, users can make secure payments by simply tapping their device on a compatible payment terminal. This technology is commonly referred to as “tap and pay” or “contactless payment.”

NFC operates at a frequency of 13.56 MHz and supports data transfer rates of up to 424 Kbps. It utilizes short-range communication and is considered relatively secure due to its short-range nature, requiring devices to be in close proximity for communication to occur.

It’s worth noting that NFC is different from Bluetooth and Wi-Fi, as it has a much shorter range and is primarily designed for quick and secure data exchange over short distances.
