No, they’ll reject it. However, some BofA BT offers allow cash deposits into a checking account (or direct deposit, if the BT is originated from BofA’s web site), so you might be able to use a check to deposit $3,500 into your checking and then use it to pay off the other BofA card. But be careful: If deposits aren’t allowed, the interest rate and fees will be very high.

Read the info. that came with the checks. Also go into your BofA account and go card by card, checking the “consolidate debt” section to see what offers are listed.
