Network tokens are unique identifiers used in place of card details during transactions. They enhance security by keeping sensitive information hidden. This article from VGS explains how network tokens work, their benefits, and their importance in payments.
- Network tokens enhance payment security by replacing sensitive card information with unique digital identifiers, significantly reducing the risk of fraud.
- The dynamic nature of network tokens allows automatic updates, ensuring seamless transactions even when card details change, which is especially beneficial for recurring payments.
- Adopting network tokenization improves authorization rates and customer experience while reducing compliance burdens and operating costs for businesses.
Understanding Network Tokens
Network tokens are unique digital identifiers that replace primary account numbers (PANs) during transactions. These tokens are designed to act as payment credentials linking a card to a specific merchant, ensuring that sensitive PAN information is never transmitted. This innovative approach drastically reduces the risk of fraud, as the actual card details are never exposed during the transaction process. Importantly, if a card number changes, due to expiration or reissuance, the associated token is automatically updated, ensuring seamless continuity for merchants and consumers.
Substituting PANs with network tokens significantly enhances the security of the payment process. Each transaction utilizes a different token, making it nearly impossible for cybercriminals to steal and misuse card information. This method not only enhances security but also builds trust between merchants and consumers, knowing that their payment information is well-protected.
How Network Tokenization Works
Network tokenization is a sophisticated process managed by card networks that generate tokens in real-time for secure transactions. The process involves:
- When a transaction is initiated, the payment service provider requests a network token from the card scheme.
- The card scheme replaces the sensitive credit or debit card data with a unique identifier (token).
- This token is accompanied by a unique cryptogram, adding an additional layer of security during the transaction.
- If a card number changes, due to expiration, loss, or reissuance, the associated token is automatically updated by the network, ensuring uninterrupted payments without requiring the consumer to re-enter their card details.
The card issuer plays a crucial role in this process by verifying the card details before the transaction is authorized. This ensures that all qualifying transactions, including card-not-present transactions and card payments, are legitimate and secure, whether they are conducted online or as recurring payments.
The dynamic nature of network tokens, which can be updated automatically, ensures that transactions remain seamless even if the underlying card details change.
Difference Between Network Tokenization and PCI Tokenization
While both network tokenization and PCI tokenization aim to secure payment data, they operate differently within the payment ecosystem. Let's break it down.
Network tokens are a set of randomized code that act as a substitute for a credit card's primary account number (PAN). Network tokens allow merchants to securely process payments without storing sensitive card details, significantly reducing the risk of fraud and data breaches while increasing token interoperability among PSPs. These tokens are issued and managed by the major card networks themselves, such as Visa, Mastercard, American Express, and Discover.
In contrast, PCI-compliant tokens are surrogate values that replace sensitive cardholder data, such as the Primary Account Number (PAN), to help businesses reduce their PCI DSS (Payment Card Industry Data Security Standard) compliance scope. These tokens are generated by a tokenization system. Typically, these tokenization systems are provided by a secure payment processor or token vault, like VGS, and are used to safely store or transmit payment information without exposing the actual card data.
Key Benefits of Network Tokenization
The benefits of network tokenization extend far beyond just enhancing security. By substituting primary account numbers with tokens, businesses can protect sensitive data, improve customer experience, and boost authorization rates. Network tokenization also helps businesses comply with PCI standards by minimizing the exposure of sensitive payment information.
Furthermore, businesses are increasingly adopting network tokenization to maximize conversion rates. Network tokens automatically update card data across networks, increasing authorization rates and successful transactions. This allows businesses to provide a more secure and seamless payment experience for customers. The following subsections will delve deeper into the specific benefits of network tokenization.
-
Enhanced Payment Security
Network tokens significantly enhance payment security by replacing sensitive information, such as card details, with unique identifiers, which protect account information from potential breaches. This process converts sensitive payment details into tokens, mitigating the risk of fraud and ensuring that merchants processing payments do not have access to sensitive credit card information.
Implementing network tokenization can potentially decrease merchants' PCI compliance burdens by limiting the exchange of sensitive data and adhering to PCI DSS requirements. Additionally, card networks update network tokens automatically, ensuring they remain valid even if the card details change, thus maintaining a secure and seamless transaction process.
-
Reduced Fraud Rates
Network tokens play a crucial role in securing payment data across all transaction stages, significantly lowering the risk of fraud. Each token generated for online purchases is unique to the retailer, limiting the impact of potential security breaches. Network token transactions enhance this security further, forming an essential part of the payments stack.
Companies like Visa have reported substantial savings in fraud losses due to their tokenization solutions, highlighting the effectiveness of this technology to reduce fraud and fraudulent activity.
-
Higher Authorization Rates
One of the most compelling benefits of network tokenization is its positive impact on payment authorization rates. On average, businesses experience a 3% increase in authorization rates when adopting network tokenization. This improvement is largely due to dynamically updated tokens that remain valid even if the primary account number changes, eliminating declines associated with expired account details.
Both Visa and Mastercard facilitate higher authorization rates through their tokenization services, potentially increasing merchant revenue by ensuring more successful transactions. Merchants adopting network tokenization can thus expect higher approval rates and increased revenue.
-
Cost Savings
Utilizing network tokens can lead to significant cost savings for businesses. By reducing transaction fees and interchange costs, network tokenization directly benefits the bottom line. Lower costs for processing tokens compared to traditional PANs result in reduced transaction costs, making it an economically viable option for merchants.
Additionally, merchants can mitigate rate increases related to non-token transactions by adopting network tokens, further contributing to overall cost savings. For example, when someone uses a PAN rather than a token, it can often carry higher fees or interchange rates. With NTs, networks typically reward this with lower processing fees that apply to non-tokenized payments.
This reduction in operating costs, combined with enhanced security and higher authorization rates, makes network tokenization a smart financial choice for businesses.
-
Improved Customer Experience
Network tokens enhance customer experience by ensuring that outdated PANs can still process payments, reducing transaction declines. This creates a smoother payment process and minimizes the need for customers to update their card information frequently.
Network tokenization provides a frictionless payment experience, reducing payment failures and enhancing security. This leads to higher customer satisfaction. Merchants using network tokens also benefit from reduced customer service issues related to transaction failures on old cards, further improving the overall customer experience.
