Smartphone application where it is possible to count the participants of the events held in the Houses of Prayer belonging to the Christian Congregation in Brazil.
Events implemented in the application: Rehearsals, Baptisms, Holy Suppers, Meeting of Young People and Minors.
You have the possibility to print the count using the printer configured in the Cellular system or print using a 58mm thermal printer, which is connected via Bluetooth. The terminal printers tested were the AS5802 and KP-1020 models. The KP-1020 printer has some flaws. The AS5802 printer works perfectly.
