What Is a Mobile Wallet? How It Works and How To Choose One

A mobile wallet is an app that stores your credit cards, debit cards and other payment information on a phone or smartwatch. Because it is available on many smartphones, it's a convenient way to pay in stores, in apps and online without using a physical card.

Here's a look at how mobile wallets work, what types are available and how to choose one that fits how you shop.

Key Takeaways

A mobile wallet stores your cards on your phone or smartwatch, so you can tap to pay in stores, in apps and online without a physical card.
There are three main types — open, closed and semi-closed. Open wallets like Apple Pay and Google Wallet work at the most merchants, while closed and semi-closed wallets are tied to one brand or a set network.
Security relies on tokenization, not your real card number. The wallet swaps your card number for a device-specific token and a one-time code, so the merchant never sees your actual account number.
You usually confirm each payment with a fingerprint, face scan or passcode, which helps protect your account if your phone is lost or stolen.
Many NFC tap-to-pay transactions work without an internet connection, though QR-code payments, setup and updates may still need Wi-Fi or data.
A stored balance may not carry the same protections as a bank account. Money kept in some payment apps may not be FDIC-insured, and transfers to a bank can take a few business days.

How Mobile Wallets Work

A mobile wallet is a type of digital wallet made for a phone or smartwatch, so you can use it to pay on the go. “Digital wallet” is the broader term and can also refer to payment tools used on a computer or through a browser.

There are four basic steps to using a mobile wallet:

Add a card. Enter the details, scan the card with your camera or connect it through your bank or card issuer. Once saved, you can reuse it for future purchases.
The wallet protects the information. It replaces your actual card number with a protected digital token and uses a transaction-specific security code, so the merchant never sees your full card number.
Choose how to pay. Depending on the wallet and merchant, hold your device near an NFC-enabled terminal, scan a QR code or select the wallet during online checkout.
Approve the purchase. Confirm it with a passcode, fingerprint, facial recognition or another form of device authentication.

The payment is then charged to the card or account you selected.

Types of Mobile Wallets: Open vs. Closed vs. Semi-Closed

There are three main types of mobile wallets: open, closed and semi-closed. The main difference is where each one can be used.

Type	How It Works	Example
Open	Works with many merchants that accept supported contactless or digital payments	Apple Pay, Google Pay
Closed	Works only within the company's own platform	Starbucks Wallet, Amazon Pay
Semi-closed	Works with a select group of merchants	Venmo

Open Wallet

An open wallet works with the most merchants because it isn't locked to one company. Add your credit or debit cards, and you can pay in stores, in apps and on websites that take that wallet. At checkout, this usually just means tapping your phone or watch at the terminal.

Closed Wallet

A closed wallet is designed mainly for one company or brand. A retailer or restaurant may let you load funds, connect a card, collect rewards and pay through its own app, but the wallet is not intended for purchases from unrelated businesses.

Semi-Closed Wallet

A semi-closed wallet sits between the two. It works across a set network of merchants and service providers that have an agreement with the wallet provider, and some let you send funds to other accounts within that same network. It's more flexible than a closed wallet, but you still can't use it just anywhere the way you can with an open one.

Which Mobile Wallet Should You Use?

For many readers, an open wallet will be the day-to-day option because Apple Pay and Google Pay are available on many smartphones and work across a broad range of merchants.

Pros and Cons of Using a Mobile Wallet

Mobile wallets are not a perfect fit for every situation. Here's a guide to help you weigh your options before relying on one. Some of the tradeoffs

Pros

Convenience: Keep several cards in one place, switch between them and check out quickly without digging through a physical wallet.
Security: Mobile wallets use features such as fingerprint or facial recognition, encryption and tokenization to help protect your payment information.
Loyalty perks: Some wallets can store rewards cards, coupons or other offers so they are easier to access at checkout.
Spend tracking: Some wallets let you view past purchases to help you review spending and stay within a budget between paychecks.

Cons

Limited acceptance: Not every merchant accepts contactless payments, QR codes or every mobile wallet, so carrying a backup card or cash can still help.
Phone dependence: A dead battery, damaged device or temporarily unavailable wallet could leave you unable to pay.
Technical problems: Terminal, app or network issues can cause a payment to fail or require another payment method.
Transfer delays: Some wallets that hold a balance may take a few business days to move money to a bank account.

Different wallets come with different tradeoffs. Open wallets work across more merchants, while closed and semi-closed wallets may be more useful for a specific retailer, merchant network or transfer need. Consider where and how you plan to pay before choosing one as your main wallet.

How To Choose the Right Mobile Wallet

Before settling on a mobile wallet, run through this checklist to see how it fits your everyday needs:

Check phone compatibility. Apple Wallet works on compatible Apple devices, Google Wallet works on supported Android phones, and Samsung Wallet works on compatible Samsung Galaxy devices. A wallet tied to a retailer or specific payment service may require a separate app.
Review supported cards and banks. Make sure the wallet accepts the credit cards, debit cards and financial institutions you use most. Some banks or cards may not work with every wallet, so check before assuming your primary card can be added. Also consider whether the wallet requires you to load funds or lets you pay directly from a linked card.
Look at merchant acceptance. Focus on the places you shop, including grocery stores, restaurants, gas stations and online retailers, and make sure they accept the wallet you are considering. A wallet that works well for tap-to-pay may not be as useful for online shopping.
Test the ease of use. Adding and removing cards, switching between them, viewing recent purchases and adjusting security settings should not be a hassle. Check whether the wallet makes it easy to lock access, receive alerts or respond if your phone is lost.

Start with the wallet built into your phone, then add another only if you need something it doesn't offer.

FAQ

What happens if I lose my phone with my mobile wallet on it?

Use the manufacturer's lost-device service to lock or erase the phone remotely. You may also be able to suspend cards in the wallet. Contact your card issuer if you notice an unauthorized transaction.

Are mobile wallets free to use?

Many mobile wallets do not charge a fee to add a card or make an everyday purchase. Fees may apply for instant transfers, currency conversion or moving a stored balance to a bank account.

Do I need Wi-Fi or data to pay with a mobile wallet in a store?

Not always. Many NFC tap-to-pay transactions work without an active connection, although some wallets limit offline payments. QR-code payments, setup and updates may still require Wi-Fi or mobile data.

Can I have more than one mobile wallet on the same phone?

Yes, a phone may support multiple compatible wallet apps. You may need to choose one as the default for contactless payments.

The best move i made to improve my credit score, was to get my full report. You can get free copies every year. I actually got a copy from all 3 of the major agencies. Then sit down with a POT of coffee and go through, in detail. Find all the errors, and i almost guarantee you, you're going to find some. Write everything down in detail. Then call the particular agency that pertains to the mistake or file a dispute if you're doing it on a certain app. This helped my score more than anything ever has. A little work but WELL worth it. Good Luck!!
