OpenEPaperLink will, on bootup, try to see if it can use NFC wake by taking some measurements on the FD line. The capability flags are updated accordingly.
It's not impossible to 'retrofit' an NFC IC on a non-NFC capable tag; the IC's are about €1.50 and can be bought at DigiKey. Additionally, a few small passives will need to be added. For OpenEPaperLink, no new firmware needs to be installed; the NFC IC should be recognized at bootup.
