<prompt> Human: Ive only used Chase Quickpay to pay my friends small amounts of money in the past. Is there any reason why its not safe to use it as a method of payment for large sums that you want to have a record of such as rent?  <response>: I dont see why not. Id definitely be sure to fill out the memo with something like John Doe Rent for XYZ Address, ABC month just like you would on a check.
