- `{card_id}` is optional - `{card_id}` is optional. This field denotes the internal LNBits ID for the card you set up.
- If you include the `{card_id}`, there is a slight potential privacy leak where each place you tap your card will see this `{card_id}` in plain-text. As one example, merchants could potentially use this static identifier for the card to build a profile around you. If you are on a shared, large LNBits host this option is probably best for you as the system is more efficient this way. - If you include the `{card_id}`, there is a slight potential privacy leak where each place you tap your card will see this `{card_id}` in plain-text.

- If you don't include `{card_id}`, then you will have gained a tiny bit more privacy by not exposing any static identifier to anyone. The downside to this is that the processing LNBits does after you tap your card is more computationally expensive. If you are on a dedicated, private LNBits instance this option is probably best for you as the efficiency gains of adding `{card_id}` are irrelevant in this use case. - If you don't include `{card_id}`, then you will have gained a tiny bit more privacy by not exposing any static identifier to anyone.
