Using Banking Apps and Electronic Payment Services Safely: A Practical Guide for Vietnamese People in the US

The Vietnamese community in the US is increasingly targeted by sophisticated cybercriminals using native-language impersonation scams. This guide provides essential security protocols and a practical checklist to help you safeguard your assets against common fraud tactics involving Zelle and international money transfer services.


Every year, Americans lose billions of dollars to online financial fraud. According to the Federal Trade Commission (FTC), in 2024 alone, American consumers reported losses exceeding 10 billion USD from scams — and electronic payment is one of the most heavily targeted channels. This article will show you how to use banking apps and electronic payment services safely, avoid fraud traps, and protect your money — whether you've just moved to the US or have been here for many years.

Banks and government agencies never ask you to transfer money urgently via Zelle, Cash App, or gift cards; if they do, it is definitely a scam.

Why Vietnamese People in the US Need to Pay Special Attention

The Vietnamese community in the US has several characteristics that make financial security more important than it is for typical local residents.

First, many people regularly send money back to Vietnam for family — meaning many international transfer transactions, which are major targets for scammers.

Second, a portion of elderly people in the community are new to technology and are more easily targeted.

Third, there are bad actors who deliberately target the Asian community by impersonating Vietnamese speakers — sending texts, making calls, or creating fake websites in Vietnamese to deceive people.

Popular Apps and Services You Need to Know

Before talking about security, let's go through the tools commonly used by Vietnamese people in the US:

Five Golden Principles When Using Banking Apps

  1. Always enable two-factor authentication (2FA)

Two-factor authentication, or 2FA, is a second lock on your account. Think of it this way: a house door has a lock (password), but 2FA is an additional lock — and the key to this lock is only sent to your phone each time you log in. Even if a bad actor knows your password, they cannot access your account without your phone.

Most major banking apps, Venmo, and PayPal support 2FA. Go to the security settings section and enable this feature today.

  1. Don't use public wifi for financial transactions

Wifi at coffee shops, pho restaurants, or shopping centers is open wifi — anyone can see the data you send if they know how. If you need to transfer money urgently but are not at home, use your phone's mobile data instead of public wifi.

  1. Set strong passwords and don't reuse them

Passwords like "123456" or your child's name plus birth year are dangerous choices. A good password should have at least 12 characters, including uppercase letters, lowercase letters, numbers, and special symbols. If you can't remember everything, use a password manager app like 1Password or Bitwarden — they save and create passwords for you.

  1. Update apps regularly

Each app update typically includes security patches. Don't ignore update notifications — they're not annoyances, they're fixes for vulnerabilities that bad actors are exploiting.

  1. Only download apps from official sources

Only download banking apps from the App Store (iPhone) or Google Play Store (Android). Never download apps from links in messages or emails — even if the sender appears to be your bank.

Common Scams Targeting the Vietnamese Community

Understanding scams is the best defense.

Bank Impersonation Scam: Bad actors call or text, pretending to be a bank employee, claiming your account has been attacked and asking you to transfer money to another "safe" account. Real banks never ask you to do this.

Zelle Fraud: According to the FTC, Zelle has no mandatory refund policy for transactions you personally make. Once money is transferred, it's nearly impossible to get it back. Scammers usually create urgent situations — "Your child was in an accident, transfer money now" — so you don't have time to think.

Vietnamese Impersonation Scam: There are criminal groups using Vietnamese to send messages, create websites, or call impersonating the IRS or USCIS, threatening you with deportation or fines unless you pay money immediately. This is a scam — the IRS never requests payment via gift cards or Zelle.

Online Job Scam: Someone promises to pay you for receiving and forwarding money. In reality, you're becoming a "money mule" — someone used to launder money — and could face criminal prosecution even though you didn't knowingly do anything wrong.

When Sending Money to Vietnam: Be Twice as Careful

Sending money home is a frequent need for many Vietnamese families in the US. Here are things to remember:

  • ✅ Only use services registered with FinCEN (Financial Crimes Enforcement Network) of the US Treasury Department — such as Wise, Remitly, Western Union, or major banks.
  • ✅ Check the exchange rate and fees before sending — don't get ripped off by large exchange rate differences.
  • ✅ Send money to the right person — confirm the recipient's account information before clicking send.
  • ❌ Don't use unofficial services or ask strangers to transfer money for you, even if they promise lower fees.
  • ❌ Don't transfer money to someone you've never met in person, even if they say they're a friend of a friend.

If You Get Scammed: What to Do Immediately

Don't panic, but you must act fast.

Step 1: Contact your bank or payment service immediately — call the number on your card or app. Request to freeze your account or reverse the transaction if there's still time.

Step 2: Report to the FTC at reportfraud.ftc.gov. This is the federal agency that specializes in handling consumer fraud cases.

Step 3: If personal information (such as your Social Security number) has been exposed, place a fraud alert or freeze your credit at the three major credit reporting companies: Equifax, Experian, and TransUnion — completely free under federal law.

Step 4: Inform the community — share information about the scam in family groups, community organizations, or community pages so others can avoid similar traps.

One Thing to Remember Forever

Banks, the IRS, or any government agency — never ask you to transfer money urgently via Zelle, Cash App, or gift cards. If anyone asks you to do this, whether they speak Vietnamese or English, it's a scam. Hang up, turn off messages, and call your bank directly using the number on your card.

Protecting your finances doesn't need to be complicated — with just a few right habits, you'll stay one step ahead of bad actors.
