Welcome to Visa Tap. Visa's Tap solution brings the convenience and security of an EMV contactless transaction into the consumer's own device. Consumers can tap the contactless card on their phone for various use cases, like sending and receiving funds through a peer-to-peer (P2P) payment, adding their card to their digital wallet, or using it as a step-up method to prove possession.
This document is intended to guide the solution providers who are participating in a Visa Tap pilot developing any of the Tap use case solutions. It explains the process of obtaining the core of Visa Tap use case solutions, Tap to Consumer Device (TTCD) SDK, and launching the Tap solution. For complete onboarding documents, contact your Visa representative. Let's get started!
o To get started with Visa Tap, reach out to your Visa representative to request participation in this program. In order to access Visa Tap on Visa Developer Center/Visa Developer Platform (VDP), solution providers must either have or create an account on Visa Developer Platform, and must sign the Visa Tap SDK License Agreement which establishes the framework, permitted use cases and conditions for launching a solution with Visa. Once the Visa Tap SDK License Agreement is signed, please follow the steps below to register your VDP accounts and get access to Visa Tap on Visa Developer Platform.
o If you already have a VDP account, proceed to Step 5 in the section below.
Steps to follow
1. To start, register for your developer account using your company emails on Visa Developer Platform unless already done. Country/region will not affect accessing Visa Tap via Visa Developer Platform.
2. Verify your account via the automated email.
3. Log into your VDP account.
4. Set your Challenge Questions.
5. After finishing setting up your VDP account, please group all the developer accounts that will need access to Visa Tap and email them to your Visa representative requesting access.
6. You will be notified by email from VDP team once the access has been approved.
o To get started with your Visa Tap solution, you will need to create a new Visa Tap project. Please note that access to the TTcD SDK is only granted with Mutual Authentication selected when creating a Visa Tap project.
o To prevent any loss of project progress, it's crucial to download your certificate private key after you have created the Visa Tap project. This certificate private key is required to establish a Two-Way SSL connection with Visa server. Your new project will be available on the dashboard. You can then download the TTcD SDK from the assets of your Visa Tap project.
Steps to follow
1. Once the access has been approved, log into your VDP account and create a new project in your dashboard.
2. Fill out the “Add New Project” form. Add a Project Name and Project Description to the fields.
3. In the Payment Methods section, select Visa Tap box.
4. In the Select Authentication Method section, make sure the Mutual Authentication is selected.
Recommended: For the Visa Tap SDK, select the default option of generating a CSR. You can find detailed instructions configuring a Two-Way SSL Keystore using CSR here.
5. Make your selection and click on ‘Create Project’ to submit.
6. Make sure to download your certificate private key. NOTE: The private key can only be downloaded at this time, and it can only be done once. Losing this key will require a restart of the VDP project. Make sure you've downloaded your private key before checking the box and clicking “Continue”.
7. Once the project is created, you can see your Visa Tap project on your dashboard. The API is optional for device enrollment since the SDK will enroll devices on your behalf.
8. Generate a Key-ID for the project. On the left sidebar of your project, select Credentials link and scroll down to Encryption/Decryption section. Click on “Generate Key-ID”.
9. You can now view the newly created Key-ID under the Encryption/Decryption section.
10. Message Level Encryption Certificate Signing Request (CSR). On the right side of your Key-ID, select “Add CSR” to generate a Certificate Signing Request (CSR) by default.
11. Now your Key-ID is activated with the Certificate Signing Request (CSR) you just uploaded.
12. Access TTcD SDK. On the left sidebar of your project, click on the Assets link to view and download all documents and SDK folder pertaining to the selected Visa Tap product.
