Walletdoc Brings Visa Payment Passkeys To South Africa

South African shoppers who have grown used to waiting for a bank redirect or one-time PIN at online checkout may soon see a simpler option at stores using Walletdoc. The payments company says merchants on its platform can now enable Visa Payment Passkeys, allowing eligible customers to approve a card purchase with the face scan, fingerprint or PIN they use to unlock their phone.

Walletdoc set out the rollout in a company-supplied announcement published by Finextra on September 29. The feature is available to its merchants, who can contact Walletdoc to switch it on. That does not mean every South African website or Visa cardholder will see it immediately. The merchant must support the checkout option, and the customer needs a compatible device and passkey enrolment.

The difference is most noticeable at the moment a payment needs approval. Instead of leaving the store page to confirm through a bank or entering a code received by SMS, a customer can authenticate on a trusted device. Once a passkey is set up for the card, later purchases on that device can use the same method. Walletdoc says biometric details stay on the customer’s device rather than being shared with the merchant.

Passkeys are not simply a faster way to press Pay. They are based on cryptographic credentials tied to a device and designed to resist phishing, a weakness of codes that can be intercepted or tricked out of a shopper. Visa’s technical overview explains that its payment passkey can work with existing card-not-present authentication systems, including 3-D Secure. The goal is to remove an extra step without removing the check that the person authorising a transaction is legitimate.

For a merchant, fewer interruptions could mean fewer abandoned baskets. Walletdoc and Visa also argue that device-based authentication can lower fraud. Those are plausible benefits, but the actual gains for South African stores will depend on how many customers enrol, how smoothly checkout works across devices and what fraud rates look like after deployment. The announcement does not provide Walletdoc-specific results from a live merchant cohort.

Walletdoc already accepts Apple Pay, Google Pay and Samsung Pay. The new option is different because it aims to bring a similar device-authentication experience to eligible Visa card payments even when the shopper is not paying through one of those wallets. South Africa’s payments market has been adding other choices as well, including QR payments in Samsung Wallet. Walletdoc’s move addresses the online card checkout rather than in-person scanning.

The practical test is whether shoppers actually see fewer failed or abandoned transactions without losing confidence in how a payment is verified. The idea is appealing because it meets people where they already authenticate every day, on their phones. But an easier checkout only becomes a meaningful improvement when merchants enable it reliably and customers understand when and how they are approving a charge.

It is also worth distinguishing a payment passkey from a password manager passkey used to sign in to an account. Here, the credential helps authorise a Visa transaction at checkout. Banks and payment networks still perform their normal roles in processing and risk decisions, and shoppers may encounter other verification steps when a passkey is not available. Walletdoc has announced an additional route through that process, not the end of every existing one-time PIN flow.
