FinDEVr SF 2015 / Checkbook

Presenter Profile

Businesses and individuals are still writing paper checks. Checkbook is solving the problem of Paper Checks by introducing Digital Checks. We have built a way for individuals/businesses to send and receive Digital Checks without the need for signing up.

Our API provides Merchants with a way to accept Digital Checks on their websites with couple of lines of code. Digital Checks can do real-time balance verification thus minimizing NSF risk present in ACH. We charge a flat fee of $1/Check or less for businesses and it’s free for individuals.


API for Digital Checks

Our presentation will show both a business as well as an individual sending a Digital Check using a browser. It will be an end-to-end experience with the beneficiary receiving and depositing the Check.

Additionally, we will demo a site using our API to receive Digital Checks and go over the API integration.
