Starting Sunday, worshippers at Saint-Francois de Molitor church in the city's 16th Arrondissement can use their debit or credit cards to donate using baskets equipped with contactless payment terminals.
"The premise is simple: An entire generation is using bills and coins less and less," the diocese of Paris said in a statement.
The five baskets keep their traditional woven design, but will accept digital donations of two to ten euros ($2.50 to $12).
Weekly collections remain a key source of financing for Catholic churches in France, accounting for 23 percent of the more than 600 million euros donated in 2016.
In Paris, the average parishioner contributes nearly 100 euros a year.
The baskets aren't the first efforts to reach out to the tech-savvy faithful. Since October 2016 eight Paris churches have accepted weekly offerings via an app called "La Quete", or The Collection.
"We increase a parish's resources because donations are two to five times higher than those in cash," said Stanislas Billot de Lochner, co-founder of Obole Digitale ("Digital Offering") which created the app.
And there's no need to worry about fellow worshippers looking askance if users just pass the basket: slips of paper confirming their donation are available at the door.
"It allows us to remove any reluctance from a churchgoer who might think, I've made an offering but people are still looking at me funny and saying to themselves, 'he didn't give anything'," Billot de Lochner said.
