[Taler] WICMP aftermath and web-based POS terminal

[Florian Jung]

Hi,

the WICMP is over and we sold almost 20% of our food and drinks via GNU 
Taler! :)


Since I couldn't make the Android POS terminal app work, Timm/Spitfire 
(in CC, but not subscribed to the list) kindly built a web-based one. It 
is now open source and can be found at

https://github.com/SpitfireX/taler-pos


It's still live, but will go down soon:

Old version (one-click buy without basket): 
https://sell.tschunk.shop/taler-pos/

New version (two-click buy with basket): 
https://sell.tschunk.shop/taler-pos2/

Both sites will ask you for a JSON which should hopefully be compatible 
to the format the Android app uses. Use 
https://sell.tschunk.shop/bar.json for best results.

(Currently, the access control is purely security-by-obscurity, though.)


Our experience with web-based solutions were positive: Some of the 
hardware we used at the points of sale were either very old (Android 
<=5), or not Android at all (laptops or Apple Phones), so they couldn't 
even run the Cashier app. Using web-based taler-pos for selling, and the 
bank webui for withdrawing coins worked well on all devices.

(Only the "Captcha" on withdrawal was a bit annoying, but one can easily 
patch that out, i guess ;)).


Thank you all once again for your kind support to make this happen :).

Cheers,

Florian
