How can I add the same food with different expiration dates?

There are two ways you can add the same food with different expiration dates:

Scan one item after another

1. Scan your food.
2. Add units, if necessary.
3. Set an expiration date.
4. Scan the same food. An option to merge both foods will be displayed, useful if you just wanted to add more units. In this case, don't do anything with it.
5. Set an expiration date for the new food card that has appeared, and the first one will be automatically archived. If you prefer to archive it manually, just swipe right the initial card before setting an expiration date on the new one.

Archive and scan

1. Scan your food.
2. Add units, if necessary.
3. Set an expiration date.
4. Swipe the card right to archive it.
5. Go back to step one.
