Very simple off the peg solution which was very easy to build and to maintain. Provided a good contactless solution for us in covid-19 times.
何が嫌いですか、または改善できると思いますか?
Some of the add ons, for example push notification systems, could do with being tested more thoroughly before being rolled out as we have had difficulties implementing them. I do think this is early days for these developments though so confident they'll improve.
