It's Sunday morning at Immanuel Baptist Church, and Jonathan Sekela is taking part in a tradition that dates to the time of the Apostle Paul, who encouraged the early Christians to set aside some of their earnings on the first day of each week as a gift for their needy brothers and sisters.
But Sekela isn't sitting in a pew waiting for a basket to be passed.
He walks up to an iPad mounted at a kiosk in the lobby, where an application called SecureGive allows him to give to the church electronically by swiping a debit or credit card.
Immanuel is one of a growing number of churches nationwide offering worshippers the option of online giving.
Never miss a local story.
"I don't usually carry cash," Sekela said, "and because of that, I often forget to take cash money to church to put in the offering."
The kiosk, he said, "kind of eliminates any excuse I had."
Sekela, 20, said many of his friends don't carry cash, either.
"It's a good idea to have some sort of electronic method at the church ... especially for the younger people," he said.
A 2013 Barna Group study found that 11 percent of all millennials donated online to a church or faith organization at least once a month, and 39 percent of practicing Christian millennials said they did.
The upcoming tech-savvy generation is one of the reasons digital giving has taken off among churches, but some local church administrators said older adults are also beginning to choose online giving.
"That's just where the banking industry is going, and it's going there very fast," said David Bourne, church administrator at Immanuel.
Kurt Braun, executive director of operations and advancement at Southland Christian Church, said offering online giving is simply part of "trying to meet people where they are."
"Folks just don't write many checks anymore," he said. "When you talk to anyone under the age of 30, they don't carry a checkbook. They just don't carry cash."
Southland began offering online giving in February in response to requests from members and, by June, 20 percent of the church's weekly giving was being done online, Braun said.
At Immanuel, online giving has been an option for more than nine years, Bourne said, but it has really taken off in the past few years.
Two years ago, Bourne said online gifts accounted for 12 percent of giving. This year, it is up to 27 percent.
In addition to giving at the kiosk in Immanuel's lobby, worshipers can contribute from their computers, or text a gift using their phones.
Gifts can be set up on a recurring basis or as a one-time donation.
While Bourne said Immanuel isn't going to stop passing the plate any time soon, "we jokingly talk about passing the iPad," he said.
Bourne said the SecureGive kiosk can be moved within the church. For example, if the youth group is taking a trip, they might bring the kiosk to the youth room so parents can pay there rather than writing a check.
He said special accounts can be set up for unique circumstances, such as collections for helping victims of a natural disaster.
In addition to convenience for members, online giving may also have benefits for the church.
Congregants who set up regular deductions from their bank accounts help "level the swings that most churches experience," said Tom Tumblin, professor of leadership and dean of the Beeson International Center at Asbury Theological Seminary.
He said most churches see spikes in giving around Christmas and Easter, with dips in between.
An electronic gift also "expedites putting that money into play for mission," Tumblin said.
While Southland's management software allowed it to set up online giving, Tumblin said many churches have opted to use third-party vendors.
They have names like EasyTithe, E-giving and SimpleGive, and the strongest companies "have fairly robust security in place," he said.
"We don't store credit card or debit card information," Bourne said. "These are companies that do this for you."
He said the church has a separate online network for SecureGive as an added layer of protection for givers.
Tumblin said the size and demographics of congregations have so far been among the primary factors determining whether a church offers digital giving, with larger churches and those with more white-collar members more likely to do so.
"I do think it'll become more common," he said.
Both Bourne and Braun said they have received no negative feedback from their congregations.
"God loves a cheerful giver," Bourne said. "We're just recognizing the way people give."
