Payment methods in Vietnam

The market

Vietnam went from cash to the phone in a few years: MoMo is the wallet most people open to pay, with about 35% of online payments by value (Decision Lab / MoMo, 2025); ZaloPay is the wallet of the Zalo messenger; VNPAY QR is the code the banking apps scan. All three confirm instantly and have no chargeback. Visa and Mastercard cover travel, subscriptions and foreign shoppers and settle at T+1 through the acquirer. The State Bank of Vietnam licenses intermediary payment services, the wallets among them, and the licensed intermediary is the party in the payment chain.

How Tranzify clients launch

A licensed client asks for the Vietnamese integrations and enables CoPay, 1DPay or VNPAY from the catalogue under its own contracts and licence; the platform runs under the client’s registration and domain, the licensed local provider performs the intermediation, and Tranzify supplies the software and the integrations. CoPay covers MoMo, ZaloPay and VNPAY QR, 1DPay MoMo and ZaloPay, VNPAY its own QR and MoMo; VNPAY QR is enabled on a client’s request, and cards go through an acquirer the client adds from the catalogue. The checkout shows the wallets first; routing by method picks the provider, and a failed wallet payment cascades to the QR. Every payment is journaled for five years and reported by webhook. Vietnam is live in the catalogue.

MoMo, ZaloPay and VNPAY QR

The wallets and the QR are deposit-only in the catalogue and settle instantly to the provider: the payer confirms in the app, the provider confirms to the platform, the platform calls the webhook. Payouts to Vietnamese payers run through CoPay or 1DPay, whose catalogue entries carry payout operations; the orchestration keeps an order open until the wallet confirms or the QR expires.
