Bank of America Corp., the largest bank in Massachusetts, confirmed Tuesday it plans to start letting customers deposit checks using their smartphones and tablet computers starting this week, becoming the latest financial institution to offer mobile deposits.

The move is another sign that the technology, which allows customers to make a deposit by snapping a picture of a check and zapping it to the bank, is becoming more common.

Several of the nation’s other large banks, including JPMorgan Chase and Citigroup, already offer similar features. Boston-based Fidelity Investments and Charles Schwab started offering the service last year. And a growing number of smaller banks and credit unions have jumped on the bandwagon as well, including Rockland Trust, Cambridge Savings Bank, and Digital Federal Credit Union in Massachusetts.

But Bank of America’s move is notable because it has such a large presence in the region.

The bank says it serves roughly half of households in Massachusetts and has more branches than any other bank in the state.

The bank will initially begin supporting the iPad on Wednesday, then gradually expand to iPhones, Windows phones, and Android devices over the next two months.
