You can deposit checks into your Baselane Banking account from any browser on your iPhone or Android mobile device. See here, for instructions on how to do so.
You will soon be able to order checkbooks for your Baselane Banking account. Please note that this is not currently possible: if you attempt to print or order checks from a 3rd party for your Baselane Banking account, the check will bounce.
In the meantime, you can pay 3rd parties via ACH and/or Domestic Wire Transfers. See here, for instructions on how to do so.
