Hi, I am looking for an app or a program which can count how many time a patron use an information center. The purpose of the app/prog is to find out a person's usage on the information center. We do not want to record what he/she uses, but would like to know the head count. I could write my own, but if there is one hosted with reasonable cost, it will be better.
The requirements are:
1. When a user come to the center, a staff will scan his/her card (with QR or other barcode)
2. The app/program record the person's info with current timestamp.
3. The app can do some statistic calculation on the data (e.g. how many times does a user come to the center? How many users use the center in a day, a month, a quote )
4. It is probably easier to have this app/program hosted by a company with minimal cost.
Many thanks in advance,
