Notes & tips
Sweet spot matters. NFC range on phones is small (~10–20 mm) and the antenna location varies by model. Train operators on where their phone's sweet spot is before they start a batch.
Under/over production is fine — capture as many or as few serials as you actually produce against the batch.
