we'd like to use membership administration for our community that is about to be founded at www.langstrasse200.ch - for various purposes we like to work with qr codes extensively. has anybody experience with this and raspberry?

hi thomas! What exactly do you need? Could you describe a use case scenario?

raot commented 6 years ago

We were talking about a more elaborate solution to manage club membership in the L200 process yesterday. To start little: the two shops that were interested in using MaziZone (http://www.haar-m.ch and https://www.chornlade.ch) as a shop-pilot were stressing their attempts to increase customer loyality. Chornlade already implemented a paper-card based solution with stamps for every purchase over chf 30, which will give back the customer some discount once the card is full. Mazizone could be used to implement the same process without the need for the customers to carry the paper with them and instead using the smartphone (a QR code that represents the custimers ID) for the same purpose. privacy concerns are addressed by the fact that mazizone is available locally only.

So the concept of an epaper display next to the point of sale was discussed to display some informaitons to the customer, i.e. account details, how mandy credits are available etc) and a QR reader attached to the same raspberry to read the customers id to connect to the account.

along with this, the user could connect to mazi zone and also take advantage of the other services available: interviews, letterbox, etc. The epaper display can also display a QR code to connect the mobile phones to the local mazi network (with some issues on apple devices).

OK, so you need the "opposite", the raspberry pi to be transformed to a QR code reader and include also some sort of local account management functionality. We need to search for both parts in the "free software" domain.

In terms of privacy, I am not sure if there is significant improvement compared to an anonymous loyalty card (I guess there are anonymous ones, no?). The fact that data are stored only locally does not seem so important for this scenario, which is "anonymous" anyway. Or I miss something?

But the idea of MAZI Zones identifying people through anonymous QR codes is very interesting and we could think of more case studies.
