The terracotta dispenser, used in the northern town of Fornaci di Briosco, functions like an automatic soap dispenser in public washrooms -- a churchgoer waves his or her hand under a sensor and the machine spurts out holy water.
"It has been a bit of a novelty. People initially were a bit shocked by this technological innovation but then they welcomed it with great enthusiasm and joy. The members of this parish have got used to it," said Father Pierangelo Motta.
Catholics entering and leaving churches usually dip their hands into fonts full of holy water -- which has been blessed by a priest -- and make the sign of the cross.
But fear of contracting the H1N1 virus has led many in Italy -- where some 15 people have died of swine flu -- not to dip their hands in the communal water font.
"It's great," said worshipper Marta Caimm as she entered the church. "Thanks to this we are not worried about catching swine flu. It is the right thing for the times," she said.
Luciano Marabese, who invented the dispenser, said he did so out of concern that fear of swine flu was eroding traditions.
And he is now blessing himself all the way to the bank.
"After all the news that some churches, like Milan's cathedral, were suspending the use of holy water fonts as a measure against swine flu, demands for my invention shot to the stars. I have received orders from all over the world," he said.
