The Swiss Post office announced a new feature to their app, which allow users to scan stamps issued from January 2017 which then presents more information about that particular issue. This started with the Christmas issue from 2016, that when scanned will lead to a short publicity video about them. The ones issued this year, however, will show a bit more background information about the theme, and in some cases short informative videos, such as that available for the baby animals set.
It still does not seem to contain much data about issue date, printing, or paper, and clicking on the shopping cart does not mean you will find your item for sale, but perhaps it can be useful for educational purposes, non-philatelists, or those just a bit curious and with some time to kill. It is, however also available in English and might be at an incipient stage.
The app is also useful, of course, to track items (using a scanner), finding agencies or letter boxes close by, check current postage rates and, among other things, buying your ‘SMS stamp’ (where the amount of the priority inland postage rate is debited from your mobile subscription and a number can be used in the place of a stamp). This last feature presents perhaps the dichotomous side of the app for stamp collectors as currently presented. Stamp promotion combined with a possibility for its eradication.
