Some do, some don’t - it varies from manufacturer to manufacturer. If things don’t work, do check that your device’s NFC reader is enabled (this can be done under your device’s settings) before you try anything else. For Apple users; we are sorry but Apple has elected to keep its NFC capabilities closed and is giving the NFC industry no clarity on its plans. This is a a real shame that they’ve gone this route but every few months there’s another rumour that’s about to change.
