@Gooner01: Sadly the Galaxy A12 does not support NFC. If you head to Settings > Connections, then the option for 'NFC and contactless payments' would usually be visible here on supported devices. As this feature cannot be installed separately, you may wish to explore some of the mid-range A Series devices, making sure to check the specifications to help you make an informed choice.

If you're looking for an option in a similar price bracket to the Galaxy A12, then I'd recommend the Galaxy A14. I hope this helps.
