A bank transfer is a method of moving money from one bank account to another. This can be done between accounts at the same bank or between different banks. Bank transfers are commonly used for paying bills, sending money to friends or family, and making purchases. They can be initiated online, through mobile apps, or in person at a bank branch. There are different types of bank transfers, including wire transfers and ACH transfers. Wire transfers are typically faster but may incur fees, while ACH transfers are often free and take a few days to process. Both methods ensure secure and reliable transactions.
