Can I attach a TD bank checking account under payment options?

Our school is looking to use jotform for our tricky tray registration. Can we attach a TD bank checking account for the payment information?

If you mean to add your bank account information in the form then yes, you can. In fact, we have this guide with details on how you can setup Paypal and Check/Bank payments:

Just please make sure not to create forms that would collect some sensitive information like passwords. You can visit our Terms of Use (http://www.jotform.com/terms/) page for more details.
