Create an NFC card as a QSL card, with one side for the cover and the other side for instructions and precautions. All communication data should be stored on the card's chip. This makes the QSL card compact and easy to store.
However, a friend said that this method of issuing cards would be very expensive, and secondly, the difficulty and cost of reading information would also be high. Although most modern phones are equipped with card readers, it is still necessary to consider that some people may not have the conditions for using them.
Personally, I find these QSL cards quite fun, so if they are made, they could be included with traditional paper QSL cards as a bonus item. I'm curious to hear what others think.
