For a mobile banking app, an e-wallet or a fintech app, money only comes in once the user passes eKYC, opens an account and makes a first transaction. This article shows how to set targets for each of those steps, which regulations to build into the funnel, and how to block fraud. It is written for bank marketing and fintech marketing teams, including foreign companies weighing Vietnam.<\/p>\n<p>The article does not explain again what fintech is, what open banking is or the concept of <a href=\"https:\/\/adtek.agency\/en\/glossary\/user-acquisition-ua\/\">user acquisition<\/a>, and it does not walk you through creating campaigns step by step, since the platforms already have their own official guides for that.<\/p>\n<h2>Vietnam fintech app users in 2026<\/h2>\n<p>In the first half of 2025, finance app installs in Vietnam grew 27% year on year on iOS and fell 39% on Android. iOS was expected to account for 54% of installs in this category in 2025, up from only 22% in 2019 (<a href=\"https:\/\/www.appsflyer.com\/resources\/reports\/app-marketing-vietnam-report\/\" target=\"_blank\" rel=\"nofollow noopener\">AppsFlyer, State of App Marketing Vietnam 2025, November 2025<\/a>). If you still put almost all of your budget into Android out of habit, it is time to look again.<\/p>\n<p>By June 26, 2026, Vietnam&#8217;s banking sector had matched biometrics for more than 162.9 million individual customer records (<a href=\"https:\/\/div.gov.vn\/ngan-hang-nha-nuoc-hop-bao-ve-ket-qua-dieu-hanh-chinh-sach-tien-te-va-hoat-dong-ngan-hang-6-thang-dau-nam-2026\" target=\"_blank\" rel=\"nofollow noopener\">State Bank of Vietnam press conference, July 2, 2026, in Vietnamese<\/a>). The number is larger than the population because one person holds records at several banks. A newly launched digital bank, or neobank, is fighting for the spot of second or third banking app on the user&#8217;s phone, so it needs a concrete reason for people to sign up: free transfers, cashback, interest rates, card limits. In digital banking in Vietnam, the people you target usually have at least one banking app already.<\/p>\n<h2>The funnel of a banking or e-wallet app: the install is only step 1<\/h2>\n<ol>\n<li><strong>Install and open the app<\/strong>, the point that <a href=\"https:\/\/adtek.agency\/en\/glossary\/mobile-attribution\/\">mobile attribution<\/a> tools record.<\/li>\n<li><strong>Registration<\/strong>: phone number, OTP.<\/li>\n<li><strong>eKYC<\/strong>: photograph the citizen ID card, match it against the chip or VNeID (the government&#8217;s electronic identification app), scan the face.<\/li>\n<li><strong>Account opened.<\/strong><\/li>\n<li><strong>First transaction<\/strong>: a top-up, a transfer, a QR payment.<\/li>\n<li><strong>Use of a profitable product<\/strong>: credit card, savings, loan.<\/li>\n<\/ol>\n<p>What is eKYC? It stands for electronic Know Your Customer: the bank verifies identity through the app instead of at a branch counter. Step 3 is decided by law, not by you. Circular 17\/2024\/TT-NHNN of the State Bank of Vietnam (effective July 1, 2024, amended by <a href=\"https:\/\/congbao.chinhphu.vn\/van-ban\/thong-tu-so-25-2025-tt-nhnn-46158.htm\" target=\"_blank\" rel=\"nofollow noopener\">Circular 25\/2025\/TT-NHNN<\/a>) requires that opening a bank account online include a biometric match against the data on the chip of the citizen ID card or an electronic identification account. From January 1, 2025, individual accounts that have not been matched cannot make electronic transactions (<a href=\"https:\/\/vanban.chinhphu.vn\/?pageid=27160&amp;docid=210565\" target=\"_blank\" rel=\"nofollow noopener\">Circular 17\/2024, Articles 17 and 23<\/a>). Opening a card or an e-wallet online has also required biometric authentication since October 1, 2024 (<a href=\"https:\/\/baochinhphu.vn\/phai-xac-thuc-sinh-trac-hoc-khi-mo-the-atm-vi-dien-tu-truc-tuyen-102240903135112058.htm\" target=\"_blank\" rel=\"nofollow noopener\">Government News, September 3, 2024, in Vietnamese<\/a>).<\/p>\n<p><a href=\"https:\/\/congbao.chinhphu.vn\/van-ban\/thong-tu-so-50-2024-tt-nhnn-43225.htm\" target=\"_blank\" rel=\"nofollow noopener\">Circular 50\/2024\/TT-NHNN<\/a> (effective January 1, 2025) keeps the rules of Decision 2345\/QD-NHNN: a single transfer above VND 10 million, a daily total above VND 20 million, or a change of the device used for Mobile Banking all require biometric authentication (<a href=\"https:\/\/div.gov.vn\/dam-bao-an-ninh-bao-mat-trong-cung-cap-va-su-dung-dich-vu-the\" target=\"_blank\" rel=\"nofollow noopener\">Deposit Insurance of Vietnam, April 2025, in Vietnamese<\/a>). <a href=\"https:\/\/congbao.chinhphu.vn\/van-ban\/thong-tu-so-77-2025-tt-nhnn-468555.htm\" target=\"_blank\" rel=\"nofollow noopener\">Circular 77\/2025\/TT-NHNN<\/a>, effective March 1, 2026, requires Mobile Banking apps to shut themselves down when they run on an emulator or on a rooted or jailbroken device.<\/p>\n<p>For the people running the ads, these banking biometric milestones mean two things:<\/p>\n<ul>\n<li>Anyone who does not have a chip-based citizen ID card at hand will drop out at step 3. The creative and the first screen should tell them in advance.<\/li>\n<li>Installs from emulators cannot get through eKYC, but if you pay per install, you still pay for them.<\/li>\n<\/ul>\n<h2>Optimize for events, not for CPI<\/h2>\n<p>CPI (cost per install) is the cost of one install. A banking app needs to look at CPA (cost per action) by event: the cost of each successful eKYC, each first transaction. Google App campaigns let you set a Target CPA on an in-app action. Google&#8217;s own example: a daily budget of USD 300 with a Target CPA of USD 10 aims for about 30 actions. To optimize for value (tROAS), the app has to send events with revenue through Firebase (<a href=\"https:\/\/support.google.com\/google-ads\/answer\/7100895?hl=en\" target=\"_blank\" rel=\"nofollow noopener\">Google Ads Help<\/a>). I covered Meta in our article on <a href=\"https:\/\/adtek.agency\/en\/meta-andromeda-advantage-plus\/\">Meta ads in 2026<\/a>.<\/p>\n<p>Pick the deepest event that still has enough volume each day for the algorithm to learn. If a new app only gets a few dozen first transactions a day, optimize for eKYC first.<\/p>\n<table>\n<thead>\n<tr>\n<th>Event<\/th>\n<th>Confirmed by<\/th>\n<th>Sent to the ad platform<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>install, registration<\/td>\n<td>The MMP&#8217;s SDK, the app<\/td>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<td>ekyc_success, account_opened<\/td>\n<td>The bank&#8217;s system<\/td>\n<td>Yes, sent from the server<\/td>\n<\/tr>\n<tr>\n<td>first_transaction<\/td>\n<td>Core banking<\/td>\n<td>Yes, with value if you optimize for value<\/td>\n<\/tr>\n<tr>\n<td>ID number, balance, account number<\/td>\n<td>Not applicable<\/td>\n<td>Never<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Events fired from the app are easy to fake through <a href=\"https:\/\/adtek.agency\/en\/glossary\/sdk-spoofing\/\">SDK spoofing<\/a>, so from step 3 onward send them from the server through your <a href=\"https:\/\/adtek.agency\/en\/glossary\/mobile-measurement-partner-mmp\/\">MMP<\/a>. For the weekly metrics set, use the framework in our article on <a href=\"https:\/\/adtek.agency\/en\/app-marketing-kpis\/\">app marketing KPIs<\/a> and add two lines: the eKYC rate per install, and <a href=\"https:\/\/adtek.agency\/en\/glossary\/retention-rate\/\">retention rate<\/a> counted by users who are still transacting.<\/p>\n<h2>A step-by-step CPA sheet (hypothetical example)<\/h2>\n<p>Hypothetical example: a Vietnam e-wallet app spends VND 200 million a month on one channel, at a CPI of VND 20,000.<\/p>\n<table>\n<thead>\n<tr>\n<th>Step<\/th>\n<th>Rate versus previous step<\/th>\n<th>Users<\/th>\n<th>Cost per user (VND)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Installs<\/td>\n<td><\/td>\n<td>10,000<\/td>\n<td>20,000<\/td>\n<\/tr>\n<tr>\n<td>Registration<\/td>\n<td>70%<\/td>\n<td>7,000<\/td>\n<td>28,571<\/td>\n<\/tr>\n<tr>\n<td>Successful eKYC<\/td>\n<td>50%<\/td>\n<td>3,500<\/td>\n<td>57,143<\/td>\n<\/tr>\n<tr>\n<td>First transaction<\/td>\n<td>60%<\/td>\n<td>2,100<\/td>\n<td>95,238<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>CPI is VND 20,000, but each user who actually transacts costs VND 95,238, almost 5 times as much. A report that only shows CPI hides this.<\/p>\n<p>Now compare two channels, also hypothetical, with 1,000 installs each:<\/p>\n<table>\n<thead>\n<tr>\n<th>Metric<\/th>\n<th>Channel A<\/th>\n<th>Channel B<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>CPI (VND)<\/td>\n<td>12,000<\/td>\n<td>30,000<\/td>\n<\/tr>\n<tr>\n<td>Successful eKYC per install<\/td>\n<td>20%<\/td>\n<td>45%<\/td>\n<\/tr>\n<tr>\n<td>First transaction after eKYC<\/td>\n<td>50%<\/td>\n<td>70%<\/td>\n<\/tr>\n<tr>\n<td>First transactions<\/td>\n<td>100<\/td>\n<td>315<\/td>\n<\/tr>\n<tr>\n<td>CPA per first transaction (VND)<\/td>\n<td>120,000<\/td>\n<td>95,238<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Channel A is 2.5 times cheaper on cost per install but 26% more expensive on the exact thing you need to buy.<\/p>\n<p>Work the CPA ceiling backward from <a href=\"https:\/\/adtek.agency\/en\/glossary\/lifetime-value-ltv\/\">LTV<\/a>:<\/p>\n<p><strong>CPA ceiling per first transaction = Average gross profit over the payback period from one user who has transacted &#8211; New user incentive<\/strong><\/p>\n<p>Hypothetical example: with a 12-month payback period, an average 12-month gross profit (after accounting for users who leave the app) of VND 300,000 and an incentive of VND 50,000, the CPA ceiling is VND 250,000. If 15% of channel B&#8217;s first transactions turn out to be fraud or bonus abuse, the real CPA is 95,238 \/ 0.85 = VND 112,045, still under the ceiling. That is the <a href=\"https:\/\/adtek.agency\/en\/glossary\/customer-acquisition-cost-cac\/\">customer acquisition cost<\/a> figure to report to management.<\/p>\n<h2>New user incentives and refer-a-friend programs<\/h2>\n<p>Digital banks and e-wallets in Vietnam attract users mostly with money: sign-up bonuses, refer-a-friend rewards (referral marketing) and affiliates paid per account opened. All three invite promo abuse. Biometric eKYC makes it hard for one person to register several times in the same app, but it does not stop people who claim the reward and then leave.<\/p>\n<p>How to build a referral program that is harder to abuse:<\/p>\n<ol>\n<li>Pay the reward on a transaction that meets a threshold, not on account opening. For example: a top-up of at least VND 100,000 and a second transaction within 7 days.<\/li>\n<li>Split the reward in two: after the first transaction, and when the user is still transacting after 30 days.<\/li>\n<li>Cap the number of rewarded sign-ups per referrer per month.<\/li>\n<li>Attach the referral code to a deferred <a href=\"https:\/\/adtek.agency\/en\/glossary\/deep-linking\/\">deep linking<\/a> link so the code follows the user through the install.<\/li>\n<li>Pay affiliates per account opened plus first transaction, hold the payment for 30 days, and ban &#8220;install the app, get cash&#8221; sources in the contract.<\/li>\n<\/ol>\n<h3>Install fraud in the finance category<\/h3>\n<p>In Q2 2025, the fraudulent install rate for finance apps in Vietnam was 43% on Android and 27% on iOS, more than double the overall market rate (<a href=\"https:\/\/www.appsflyer.com\/resources\/reports\/app-marketing-vietnam-report\/\" target=\"_blank\" rel=\"nofollow noopener\">AppsFlyer, November 2025<\/a>).<\/p>\n<p>Fraud is also moving. Globally, the share of finance fraud that is affiliate fraud fell from 58% to 49%, the share hidden in organic installs rose from 35% to 46%, and finance accounted for 33% of attribution hijacking on Android (<a href=\"https:\/\/www.appsflyer.com\/resources\/reports\/state-fraud-marketers-report\/\" target=\"_blank\" rel=\"nofollow noopener\">AppsFlyer State of Fraud for Marketers 2026, April 2026<\/a>). Fraudsters use <a href=\"https:\/\/adtek.agency\/en\/glossary\/click-injection\/\">click injection<\/a> to claim credit for people who downloaded the app on their own, and you end up paying for an <a href=\"https:\/\/adtek.agency\/en\/glossary\/organic-install\/\">organic install<\/a>.<\/p>\n<p>Three signals to check every week: organic installs dropping right when a new partner goes live; one source&#8217;s <a href=\"https:\/\/adtek.agency\/en\/glossary\/click-to-install-time-ctit\/\">CTIT<\/a> bunching unusually at a few seconds; a source with many installs but a much lower eKYC rate. To measure how many real users a channel adds, use <a href=\"https:\/\/adtek.agency\/en\/incrementality-testing-for-marketers\/\">incrementality testing<\/a>.<\/p>\n<h2>Channels and creative for banking and fintech apps<\/h2>\n<p>In digital banking marketing, the main channels are still Google, Meta, TikTok, Apple Ads, affiliates and KOLs (key opinion leaders). A fintech marketing strategy built on them follows the general methods in our article on <a href=\"https:\/\/adtek.agency\/en\/app-marketing-strategy\/\">app marketing strategy<\/a>. The product page should say clearly that a chip-based citizen ID card is required (preparing the product page is covered in our article on <a href=\"https:\/\/adtek.agency\/en\/app-launch-checklist-app-store-google-play\/\">launching an app on the App Store<\/a>). Creative worth testing first: a screen recording of the real eKYC flow, one reason to open an account online per video, and the offer conditions written in the very first frame.<\/p>\n<p>Law No. 75\/2025\/QH15 amending the Advertising Law (effective January 1, 2026) requires notes and warnings to be clear, in type no smaller than the other text in the ad. Influencers must verify the credibility of the advertiser, may not promote a service they have not used or do not fully understand, and must disclose the advertising right before and during the ad (<a href=\"https:\/\/congbao.chinhphu.vn\/van-ban\/luat-so-75-2025-qh15-45566\/57708.htm\" target=\"_blank\" rel=\"nofollow noopener\">Articles 15a and 19<\/a>). Financial services marketing runs into this more than any other category, because the offer always comes with conditions. A KOL video saying &#8220;open an account, get 100k&#8221; with the conditions hidden in small print at the end is the kind of ad to drop.<\/p>\n<h2>Financial advertising policies on Google, Meta and TikTok<\/h2>\n<table>\n<thead>\n<tr>\n<th>Platform<\/th>\n<th>Rules that apply when running in Vietnam (checked October 2026)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Google Ads<\/td>\n<td>State the business address and all fees.
