Dear Experts, VISA stores the Token in a secured format in the mobile local storage such as keystore/keychain using the API provided by VTS SDK. But when the mobile app is uninstalled, does VTS SDK take care of removing the tokens in the local storage? Thank You Paul

Dear Diana, Just to keep you updated with the information I received it from Visa Deck that there is an API replenishODA, which returns the ODA Data iccPubKeyCert field and supports certificate renewal from VTS. Request you to please validate my findings. Thank You Paul

Hello Visa Team, Does VTS support the offline data authentication (ODA) data replenishment scenarios. If so, how can the mobile application platform check on the token status and authenticate the validity. Thank You Paul

Hello Experts, In my mobile wallet, If I use same credit card in two different mobile devices, Would there be only one visa token key generated for a PAN(16 digit credit card number) or different PAN for the same PAN for both mobile devices. I heard the Visa token is generated and stored at Visa Token Vault. If so, would the token generated is linked to device, card number etc. Appreciate your inputs. Thank You Paul

Hello DianaTran-Yee, For your kind review on the below identified steps for NFC Payment at POS Terminals Using VTS: 1. Cardholder selects the token requestor payment functionality to pay for an online purchase, selecting a card account that has previously been tokenized. 2. Token requestor submits a request to VTS for a token cryptogram payload. 3. Visa generates the issuer keys used to create the token cryptograms. 4. Token requestor receives the token payload from VTS. 5. Merchant populates the payment authorization sent by its acquirer to Visa. 6. VTS performs detokenization and forwards the payment authorization to the issuer. Note: Basic issuers do not receive any token data or indicators. The transaction authorization only contains the underlying PAN data. 7. Issuer authorizes the PAN-based payment and Visa forwards the result to the merchant through the token requestor’s acquirer. The above steps are referred to Visa documentation for VTS implementation. Thank You Paul

Hello @malharzi In your consumer app, where the NFC feature is enabled in the device. The consumer initiates a payment by tapping an NFC device at the merchant site. The App will initiate a push payment request presenting the token key and payment details(acquirer account, payment amount) to VTS. The VTS will check the eligibility with Issuer(Consumer Bank) and if approved, initiates the payment transfer to the acquirer bank account. Upon successful response from the acquirer, the merchant is notified by Visa and also the consumer is notified. The API for NFC Payment is similar to mobilepushpayment API in mVisa. @Diana, Please correct me if my flow mentioned above is incorrect. Thank You Paul

Hello Visa Experts, Our banking credit card mobile app will be integrated to VTS for tokenization of cards for payment purpose. As VTS APIs are restricted(yet to receive from Visa Team), I would like to know what are all the data to be sent from Mobile App to VTS. 1. PAN (Credit Card Number) 2. Token Key (Generated by VTS) 3. Biometric Fingerprint / Face ID / mPIN (this is required for banking host to authenticate, but does VTS require it) 4. ??? I assume VTS expects the MAP(Mobile Application Platform) to perform the authentication and just pass the PAN / Token information. Appreciate your inputs on the Authentication of the Card used for payment. Thank You Paul

Hello Piracha, Regarding the NFC using iPhone: The iPhone 6 and 6 Plus have NFC, but only for payments. They cannot scan NFC tags either with or without an App. The iPhones 7, 8 and X also have NFC for payments but additionally, with iOS 11 and an NFC App, they can read NFC tags. The latest iPhone XS, XS Max and XR have NFC for payments and can read NFC tags with or without an additional App. In addition, the iPhone XS and XR can encode NFC tags when running the latest iOS 13 software. The latest generation of iPhones, the XS, XS Max and XR are the first to be able to read NFC out of box. It’s not known whether Apple will add native tag reading into any previous generations of iPhone. Regarding the SDK from Visa: @Diana - I am sure, the SDK is available for Android. But Visa should confirm, whether they have SDK for iOS to support NFC. Regards, Paul

@ritika Your reply is regarding the Mastercard DSRP which also supports VTS and the NBI Clearance is applicable for Philippines. Although it might be correct for Mastercard implementation and philippines region, but might mislead for Visa implementation team like us. But I appreciate for sharing your inputs. @Visa Moderators / Diana, Request you to please validate the reply from ritika for records purposes. Thank You Paul

Hello Visa, Q1. To the sample code downloaded found in my developer dashboard, if I make any modifications (customization) to the sample code, how would I re-submit it back to Visa. Q2. Are there any online IDE inside the developer.visa.com portal for editing the Sample code in VISA itself? Q3. If I access the Visa Direct API as REST from my back-end code, would there be a dedicated REST API URL given or its same as mentioned in the sandbox.developer.com. Thank You Paul

Hello Diana, Thank you for your reply. In fact, the links that you sent contains API for mVISA, VISA Alias, Visa Receive. Whereas I am looking for MobilePushPayment REST API (not the MobilePushPayment Refund API), a similar one in the Push Payments - Android - Consumer SDK Documentation for QR Payment. Kindly please advise. Thank You Paul

Hello Experts, Can I use VISA API or SDK to integrate my client(Bank) Mobile App for payments initiated for different card types such as Visa, MasterCard, JCB, UPI (Unified Payment Interface). For sure, we are going to use VTS Provisioning and Lifecycle Management API to tokenize VISA cards and integrate for payments with Card Management System. Kindly advise me for the VISA support as there are too many products having similar API ( i might be wrong as Im a new bie), Awaiting your guidance, Thank You Paul

Hello Visa Team, We are developing Mobile Application on-behalf of the bank for VISA Tokenization. I have registered as a Visa Developer account wherein I can see only the name of the APIs in VTS Provisioning but I could not add those APIs in my project (Visa Sandbox). Please advise us the process to avail the API or any VISA representatives details to get the onboarding done as soon as possible. Thank You. Paul
