What are digital wallets?

Where a physical wallet is a tangible item used to carry and store valuable items such as cash, credit cards, and identification documents, a digital wallet is an electronic software program that stores and manages various forms of digital currency or financial assets.

Digital wallets store users’ payment information, enabling them to make purchases and track their payment history on any device with a web browser. “Digital wallet” is an all-encompassing term to describe any wallet that exists in digital form, so while the terms “eWallet” and “mobile wallet” are often used interchangeably, they’re slight variations of a digital wallet.

What are mobile wallets?

A mobile wallet is a specific type of digital wallet in which all payment credentials, authentication information and funds are stored on a mobile device.

How do digital wallets differ from digital currency wallets?

A digital currency wallet, referred to as a cryptocurrency wallet or a crypto wallet, is a digital wallet designed specifically to hold public and private cryptographic keys. Public keys enable others to make payments to a user’s wallet, while private keys enable users to make payments using their digital currency.

Digital wallets belong to one of several categories:

  • Mobile wallets: Digital wallets that are installed as mobile applications on smartphones or tablets. Mobile wallets enable users to make payments using their devices, usually via near-field communication (NFC) or by scanning QR codes at point-of-sale terminals.
  • eWallets: An electronic wallet (eWallet) stores payment card information and facilitates electronic transactions. Popular eWallets such as PayPal or Amazon Pay are mostly used for online transactions and peer-to-peer transfers, though some allow for in-store payments.
  • Online wallets: These are web-based digital wallet apps that users can access through internet browsers on their computers or mobile devices. They are often used for online shopping and transactions on eCommerce websites.
  • Prepaid wallets: Prepaid wallets are funded in advance, either by transferring money from a bank account or by using cash at designated locations. Users can spend from the prepaid balance until it is depleted, and then they need to reload the wallet.
  • Bank-linked wallets: This type is linked directly to a user’s bank account. When making a payment, the amount is deducted directly from the bank balance or charged to the associated credit/debit card.
  • Closed wallets: These eWallets are typically tied to specific merchants or services and can only be used for transactions within their ecosystem. Examples of popular closed wallets include Amazon Pay and Starbucks Rewards.
  • Open wallets: These enable users to make transactions across various merchants and services, making them more versatile and widely accepted. Examples of popular open wallets include PayPal and Google Pay.
  • Cryptocurrency wallets: Cryptocurrency wallets are specifically to store and manage cryptocurrencies. They can be software-based (online or mobile) or hardware (physical devices).
  • Peer-to-peer (P2P) wallets: P2P wallets enable users to transfer money directly to friends, family, or acquaintances. They are commonly used for splitting bills, sharing expenses, or sending gifts.

How do digital wallets work?

Whether accessed through desktops, laptops, or mobile devices, all digital wallets store a user’s banking information. This enables the user to store, manage, and transfer digital currency or financial assets.

At a more granular level, different digital wallets use different technologies to function. For example, some use near-field communication to exchange information between mobile or smart devices, while others send a secure magnetic transmission signal to payment terminals or use QR codes to complete the purchase.

What else can digital wallets do?

Though they were initially designed to store payment details and/or banking information, the applications for digital wallets have greatly expanded. Today, many digital wallets can store a wide variety of information, including:

  • Gift cards
  • Membership cards
  • Insurance cards
  • Loyalty cards
  • Event tickets
  • Coupons
  • Receipts
  • Boarding passes
  • Hotel reservations
  • ID cards
  • Billing statements
  • Cryptocurrency
  • Spending trackers

As digital wallet technology becomes more advanced over time, many providers have incorporated additional features including tracking expenses, splitting payments, earning membership and loyalty program rewards, or requesting a reimbursement.

What types of transactions do digital wallets support?

Digital wallets support a wide variety of transaction types, including:

  • Wallet-to-bank transfers
  • Third-party transfers
