The system comprises of the following components
1. A colour touch screen showing a calender that shows a configurable number of days.
2. A MiFare RFID reader/programmer for ID and registration purposes
3. A Text messaging service which sends alerts and receives simple messages
4. A mySql database server for all data.
The system will involve being able to book a time slot, receive a reminder and cancel the booking via SMS.
Having thought further about the functionality I have decided that it should be web based with an accompanying Smart Phone APP.
Here you can see an example of the type of thing i am trying to create. It should be visually very slick and modern.
