Top 5 Case Studies of eWallet Success

You’ve learned about the basics of eWallets. And now, it’s time to discover five successful eWallet apps based on different types and understand what has contributed to their triumph.

Closed eWallets

A closed eWallet, also known as a closed-loop wallet, is a digital payment solution that enables users to conduct transactions exclusively within a predetermined, regulated setting, such as with a single service provider, brand, or merchant. 

This type of eWallet is developed by companies selling products or services to customers. 

The funds stored in a closed eWallet can only be used for transactions with the issuer of the wallet. The money from cancellations, returns, or refunds is often stored in these wallets.

Example: Starbucks


Starbucks, a renowned coffeehouse chain, has successfully implemented a closed-loop eWallet system through its mobile app. Here are some features that contribute to its eWallet’s success:

Closed-Loop Ecosystem

The Starbucks app, often referred to as a single-purpose wallet, is exclusive to Starbucks stores. This exclusivity offers substantial benefits, such as loyalty rewards and personalized incentives, fostering stronger customer-retailer bonds. 

Loyalty Programs

Starbucks Rewards is often regarded as one of the best retail loyalty programs, with 28.7 million active members as of October 2022. The program allows members to earn Stars (loyalty points) towards free items.

Targeted Marketing

Starbucks has effectively utilized its abundant data for targeted marketing. The mobile app update started targeting customers with discounts and rewards on certain items based on their purchase history. 

Semi-Closed eWallets

A semi-closed eWallet is a digital payment solution that allows users to conduct transactions at a predefined set of merchants or locations. 

Unlike closed eWallets, semi-closed eWallets offer a bit more flexibility as they are not restricted to a single service provider or merchant. However, these wallets do not permit cash withdrawals or redemptions by the wallet holder.

Example: Venmo


Venmo, a mobile payment platform owned by PayPal, is a successful example of a semi-closed eWallet for these features:

Peer-to-Peer Transfers

Venmo is known for its peer-to-peer (P2P) money transfers and payments. Users can send money to and request money from anyone who has a Venmo account. This feature makes it easy to split shared expenses like dinner bills or rent.

Social Features

One of the unique aspects of Venmo is its integration of social media elements with financial transactions. Users can add friends, share payments as part of their feeds, and even like or comment on transactions. This social aspect has made Venmo particularly popular among younger users who appreciate the connectivity it provides.

Integration with External Platforms

Venmo has also made strides in integrating with external platforms. Starting in May 2023, Venmo launched the ability for its customers to transfer Bitcoin to other Venmo users, PayPal accounts, and external wallets and exchanges. This move was in response to increasing customer demand for digital asset management options.

Open eWallets

An open eWallet, also known as an open-loop wallet, is a digital payment solution that allows users to conduct transactions across a wide range of merchants and even withdraw cash at ATMs. 

Open eWallets are typically issued by banks or institutions partnered with banks. They offer the most flexibility among the eWallet types, supporting transactions at numerous merchants, cash withdrawals, and fund transfers. 

Example: Google Pay

Google Pay

Google Pay is a successful example of an open-loop eWallet platform with these features:

Acceptance Across Diverse Merchants

Google Pay is accepted at a wide range of merchants, both online and in physical stores. Users can make purchases directly from Google or third-party merchants within the Google Pay app. This wide acceptance makes Google Pay a versatile and convenient payment solution for users.

Multiple Funding Sources

Google Pay allows many payment methods such as bank accounts, debit cards, and credit cards. Users can add their payment information to Google Pay, and the app securely stores this information for future transactions. 


Google Pay exhibits strong interoperability, allowing users to send and receive money from various mobile wallets. This feature enhances the flexibility and convenience of Google Pay, hence making it a popular choice among users for digital transactions. 

The interoperability of Google Pay is a testament to the advancements in eWallet app development, demonstrating the potential of open eWallets in facilitating seamless digital transactions.

Crypto eWallets

A crypto eWallet is a digital platform that empowers users to manage their digital currencies. 

Unlike conventional wallets, these digital wallets don’t physically store cryptocurrencies. Instead, they safeguard the public and private keys needed to conduct cryptocurrency transactions. 

They offer a user-friendly interface for managing crypto balances and facilitating transfers via the blockchain. Some even extend their functionality to allow interaction with decentralized applications (dApps).

Example: Coinbase


Coinbase is a leading crypto wallet that inspires eWallet app development for some reasons below:

Secure Digital Asset Storage

When you purchase, receive, or hold digital assets with a account, they are securely ‘custodied’ in a hosted digital asset wallet for your benefit. These assets are always yours and never become the property of Coinbase. 

Coinbase employs offline storage as a critical security method against cybercrime. Sensitive data, which would typically be on their servers, is entirely disconnected from the Internet. 

This data is then redundantly split, encrypted with AES-256, and transferred to FIPS-140 USB drives and paper backups. These drives and backups are geographically distributed in safe deposit boxes and vaults worldwide.

Blockchain Integration

Coinbase seamlessly integrates with the blockchain using its open-source toolkit, Rosetta. Rosetta simplifies blockchain integration, making it quicker and more reliable than native integration. 

IoT eWallets

An IoT eWallet is a type of digital wallet that interacts with Internet of Things (IoT) technology. 

IoT eWallets operate with e-money and virtual currencies. Further, they enable payments from wearable devices, appliances, and other everyday objects. 

Since IoT devices are already online, users don’t need a separate device to access their digital wallet. This opens up a new field for eWallet app development, creating opportunities for more seamless and integrated payment solutions.

Example: Samsung Pay

Samsung Pay

Samsung Pay is a typical example of IoT eWallets with outstanding features as follows:

Seamless Contactless Payments with Wearables

Samsung Pay enables transactions through compatible devices manufactured by Samsung. 

To make a payment with your Samsung Watch, you press and hold the Back key for around one second, scroll through the cards list, select a card, and tap PAY. This provides a seamless and simple checkout experience.

High Data Security

Samsung Pay is considered safe as it doesn’t store actual card information and uses tokenization to create a unique identifier used to complete transactions. Each transaction must be authenticated with a PIN, pattern, fingerprint, or face scan.
