 Today's topic is NFC for surfacing and maintenance. NFC can be used in factory and warehouse to pre-configure products on things like serial number, language or any set of data. Moreover, once the products are installed in the field, at home for instance, end users can still benefit from the NFC technology for both maintenance and monitoring. We can benefit from the embedded NFC dynamic tags which can simplify maintenance and diagnostic operations in the field. Traditionally, these operations have to be done with a wired interface, making the whole process complex and time consuming. Now the NFC dynamic tags can make the whole process smooth and contactless. The service personnel can read the error code and update firmware even with devices powered off, and know other wireless connectivity like Bluetooth or Wi-Fi is needed. Furthermore, end users could easily use their Android phones or iPhone with iOS 14 and above to access product pages, warranty information and download user apps to configure devices, especially those without a screen or touchpad. All of these use cases could be supported by ST25DV. Let's see how. Let me show you a handy application of NFC technology for embedded electronics. With the help of an NFC dynamic tag, you could access any electronic device and you could also interact with it easily with your NFC-enabled smartphone. For this demo, we have taken a ST25DV discovery board and placed it inside the washing machine front panel to simulate the real-life product. The machine has been running fine for a number of months. Let's imagine that suddenly it breaks down and I want to fix it quickly, but there is no technician available right now. Also, sending technicians hard into the field comes at a cost for customer health centers. So what if I could easily download the important information with my smartphone, such as the controller board number or the exact error code. Upon receiving this data, the support center could tell me how to fix the problem or could decide to send a technician. So with the simple remote assistance, we have seen that you can unlock the machine with your smartphone, which turns into a useful troubleshooting tool. I could even update the firmware on the board running on my machine with the NFC. Now let's talk about another use case of NFC that could be used for auditing devices in the field, for example. Let's take an automated laundry owner who owns multiple equipment and would like to monitor the daily usage of his machines. So with the ST25DV fast transfer mode, the mailbox mechanism will come into play and allow communication between the STM32 and your phone through the dynamic tag. This memory buffer can send up to 256 bytes of commands. We have seen the data now uploaded and the requesting information appears on the phone screen. Password protection is also possible to ensure that only the right people have access to the information. So to sum it up, we have seen that with RFID NFC technology, you can add two advantages to your product. The first one is that the factory when boards are ready to be shipped and you can still program them. And the second advantage is that you continue to benefit from your NFC circuit once the product is already in the field and you rely on the NFC technology that is already in your phone. To wrap up, RFID technology can benefit the whole product life cycle by making manufacturing process and warehouse operations more efficient and also improving servicing, maintenance and end user experience. Last but not least, there are several kits available to get you started including a discovery kit for evaluation, a nuclear board for development with STM32 and an antenna reference design.
