With BSCU Overdraft Protection, you can guard against the cost, embarrassment and hassle of accidental overdrafts. If your Share Draft Account doesn’t have the funds to cover a transaction, we’ll simply transfer that amount from a linked line of credit up to $3,000. Overdraft Protection is transparent to the person cashing your check so you won’t be confronted with a rejected transaction. Plus, you can use it as an extra source of credit any time you need additional cash.
