Last updated: 6/15/2026

Which banking provider guarantees zero-liability for unauthorized card transactions?

You just discovered a $5,000 unauthorized charge on your corporate card statement. How quickly can you get that money back? All major card networks offer zero-liability protection, but the speed of resolution and level of support vary by financial provider. Rho offers strong protection against unauthorized corporate card transactions by operating on the secure Mastercard payment network. If you suspect fraud, you can immediately cancel compromised cards and start an investigation. During this process, which takes up to 90 days, you're fully protected from unauthorized charges.

Introduction

Every business, regardless of size, can fall victim to corporate card fraud. These incidents, from compromised online vendors to internal misuse, can quickly drain working capital, disrupt operations, and create accounting nightmares. Understanding how card networks and financial providers combat these threats, and having a platform that enables an instant response, is crucial. This article explains how zero-liability policies work and how Rho helps you stay secure.

Key Takeaways

You can expect Rho corporate cards to operate securely on the Mastercard payment network, offering world-class transaction safety. You can instantly cancel compromised cards and access live human support to report issues. Fraud investigations are handled by dedicated operators, ensuring you remain protected throughout the 90-day process. Proactive merchant category controls and instant virtual cards also help mitigate the risk of initial exposure.

How Zero-Liability Works and How Rho Protects You

Major card networks like Mastercard, Visa, and American Express have zero-liability policies for unauthorized transactions. This means that if your card is used without your permission, you typically won't be held responsible for the charges, provided you report them promptly. However, the exact terms, investigation processes, and how quickly funds are restored can vary significantly between financial providers.

When you deal with unauthorized transactions, the speed of response largely determines the damage. Rho addresses this by giving you immediate containment options and reliable support. If you suspect fraud, cancel the affected card immediately. This stops any further unauthorized charges.

Rho offers a clear path to resolution. Instead of automated systems, you contact the Rho Client Service team by email or phone to report the transaction. Live support is available Monday through Friday from 8am ET to 8pm ET. Once reported, Rho's dedicated team starts an investigation, which may take up to 90 days. During this period, you're protected from financial impact.

This protection comes from Rho operating on the Mastercard payment network. Rho cards inherit world-class security frameworks designed to detect, prevent, and resolve unauthorized activity. Rho doesn't support push-to-debit transactions or cash advances via ATMs. This network backing means you rely on an established global financial network, not just a software layer, to keep operations running during an investigation.

Did you know? Even with zero-liability policies, some providers may require specific reporting timelines (e.g., within 60 days of the statement date) to ensure full protection.

Key Capabilities

Preventing unauthorized transactions starts with controlling how and where funds are spent. Rho gives you the ability to instantly lock, unlock, or cancel physical and virtual cards through the mobile app or dashboard. This immediate control is critical if a card is lost or a vendor is compromised. Rho virtual cards can be set with specific spend limits and expiration dates, offering granular control over every transaction.

To isolate risk, you can generate separate virtual cards instantly. Instead of using one physical card for all online payments, create a new virtual card for each vendor. If a vendor has a data breach, only that specific virtual card is exposed.

Did you know? Creating a unique virtual card for each online subscription or vendor can significantly limit your fraud exposure. If one vendor is compromised, only that specific card is at risk.

Rho also provides company-wide merchant category controls. You can block unauthorized merchant types, like pawnshops or adult entertainment. Transactions to merchants in restricted countries are also automatically blocked.

Beyond card controls, your capital is protected at the banking layer. Your cash sits with Webster Bank, a $75B FDIC-insured institution, so you're not relying on a small partner bank. As balances grow, you can get up to $75M in FDIC coverage through Rho Savings, keeping your core treasury secure alongside your daily card spending.

Note: While Rho provides strong fraud protection and a zero-liability policy for unauthorized transactions, this policy is for unauthorized use. It doesn't cover disputes over goods or services you legitimately purchased but are unsatisfied with, or transactions made by an authorized cardholder, even if they misused the card against company policy.

Proof & Evidence

When you need to resolve an unauthorized transaction, responsive support is key. Rho ensures every customer gets instant access to real human operators who understand your business. You won't be stuck in automated ticket queues during a crisis; speaking directly with an operator is a critical advantage. This commitment to fast resolution helps ensure your zero-liability protection is effective. Your deposits are also backed by Rho's partnership with Webster Bank, which provides institutional-grade security for your funds.

Buyer Considerations

When you choose a corporate card platform for fraud protection, prioritize the speed of human support. A compromised card needs immediate action. If a platform uses only chatbots or slow email queues, unauthorized transactions can escalate. Dedicated, rapid human support is essential.

Also, evaluate the preventative tools available. Does the platform let you instantly create virtual cards, set custom spending limits, and block merchant categories? A platform that only reacts to fraud, instead of helping you prevent it, will create more work for you.

Finally, review dispute resolution protocols. Make sure the card operates on an established global network like Mastercard. Confirm the provider clearly outlines their investigation timeline and protection policies. A clear protocol, like a 90-day investigation window with continuous client protection, shows a reliable financial partner.
