To transfer money between accounts, you typically need to access your bank's website, mobile app, or visit a branch in person. Online, log in to your account, select 'Transfer' or 'Send Money,' choose the recipient account (either yours or another person's), enter the amount and date, review the details, and confirm. For transfers between your own accounts at the same bank, the process is usually instant or completes within one business day. For transfers to accounts at different banks, you'll need the recipient's routing number and account number; these transfers typically take 1–3 business days. You can also use alternative methods like wire transfers (faster but with fees), ACH transfers (free or low-cost), mobile payment apps (Venmo, PayPal, Square Cash), or checks. ATM transfers are available at some banks. For international transfers, use services like Western Union, MoneyGram, or your bank's international wire service. Each method has different fees, speed, and daily limits—check your bank's terms. Always verify recipient details carefully before confirming to avoid sending money to the wrong person. Some transfers require additional authentication like two-factor verification for security.
