Companies Building Secure E-Wallet Apps for Modern Payment Businesses

Digital wallets have evolved from simple alternatives to physical cards into full payment products that may support P2P transfers, merchant payments, multiple currencies, loyalty programs, virtual cards, transaction histories, and connections to banking infrastructure. For payment businesses, building these products requires more than an attractive mobile interface. The underlying system has to protect financial data, process transactions reliably, integrate with payment providers, and remain stable as transaction volumes increase.

For companies comparing an e wallet app development company, security and payment-domain experience are therefore important evaluation criteria. A development partner may need to work with authentication, transaction monitoring, payment gateways, KYC/AML providers, card infrastructure, APIs, back-office systems, and reconciliation processes within the same product. Mobile security frameworks such as the OWASP Mobile Application Security Verification Standard can also provide useful guidance for areas such as authentication, secure storage, cryptography, network communication, and application resilience.

The companies below work with digital wallets, payment platforms, fintech applications, or closely related financial infrastructure. They differ in their approach: some focus primarily on custom development, while others provide ready-made fintech platforms that can serve as the technical foundation for a wallet.

Andersen	Custom development	E-money, wallets, payment systems	Complex payment infrastructure
Netguru	Product development	Wallets and P2P payments	UX-focused fintech products

Original comparison table created for this article based on the companies' publicly described services.

Each company brings a slightly different mix of engineering depth, industry focus, and integration experience to a wallet project. The table below summarizes what stands out about each one.

Key Highlights

Company	What Stands Out
DeepInspire	Fintech-focused custom development covering the full stack — backend, frontend, architecture, cloud/DevOps, UX/UI, QA, and product management — plus experience with fiat and crypto digital banking wallets. A fit for businesses that need a custom wallet as part of a broader financial ecosystem.
ScienceSoft	Payment software specialist with a mobile payment app built for a system serving millions of e-wallet users (balances, payments, transfers, top-ups, withdrawals). Strong fit when the wallet needs to connect with payment gateways or banking infrastructure.
Appinventiv	Dedicated e-wallet and fintech app development, with engineering work spanning payment rails, ledgers, card infrastructure, and compliance. Suited to consumer-facing wallets and mobile-first payment apps.
Andersen	Builds custom digital wallets and e-money software for fintechs, neobanks, banks, and licensed e-money institutions, with strong integration work across gateways, card networks, and open-banking APIs. Best for projects with heavy integration needs.
Netguru	Combines product design and UX with wallet and P2P payment engineering, e.g. Careem Pay. A good match where customer experience is as important as the underlying payment engineering, with attention to PCI DSS and KYC/AML considerations.

 

What Should Payment Businesses Evaluate?

Security should be assessed across the full wallet architecture rather than treated as a single feature. Authentication, authorization, encrypted communication, secure data storage, infrastructure security, transaction controls, auditability, and application testing all contribute to the security of a payment product. When cardholder data enters the system, PCI DSS requirements may also become relevant; PCI DSS 4.0.1 remains part of the PCI DSS 4.x standard family.

Payment businesses should also examine whether a potential development company has experience with the specific infrastructure their product will require. A consumer wallet connected to cards and payment gateways presents different technical challenges from an e-money platform, multicurrency business wallet, embedded wallet, or large-scale P2P payment system.

There is consequently no single development company that fits every wallet project. The appropriate choice depends on whether the business needs custom development or an existing fintech platform, which payment rails must be integrated, the markets where the product will operate, expected transaction volumes, compliance obligations, and the amount of control required over the underlying architecture.
