This guide explains when a vendor’s claim of 60% lower authorization costs is verifiable rather than merely asserted. It sets a same-merchant test covering authorization attempts, approval rates, costs, and fraud losses.
How tokenized card authorization works
At authorization time, the card network replaces the customer’s primary account number (PAN) with a network-issued, 16-digit surrogate. The token is PAN-shaped, allowing existing payment fields to carry it, but it is not valid for direct use outside the network’s controlled authorization path. Its relationship to the underlying account is maintained in the network’s token vault rather than in the merchant’s systems. For a given customer and merchant, the network may generate a device-specific token or dynamically cryptogram alongside the surrogate, binding each authorization attempt to its device and transaction context.
The sequence is straightforward. During provisioning, the merchant or payment client establishes a token relationship with the card network and receives the surrogate instead of retaining the underlying PAN for later use. At checkout, the merchant sends the token to its payment gateway, which forwards it through the acquiring and authorization network. The issuer verifies the request, the network retrieves the account mapping from its token vault, and the approval or decline is returned using the token reference. A practical check is to inspect both payment records and downstream processor logs: the authorization request should carry the surrogate, while the real PAN should not appear in the merchant’s recurring transaction data.
Tokenization is not another form of encryption. Encryption protects PAN data while it is being transmitted or stored but leaves a decryptable value in systems that hold the key. Tokenization replaces the sensitive value with a different instrument. After the initial provisioning event, the merchant does not hold a decryptable PAN that can be recovered from the token. A merchant breach can therefore expose a static surrogate and associated transaction data without exposing the underlying 16-digit card number. The operative comparison is not “encrypted versus plaintext”; it is whether the merchant can reconstruct the card number from the credential it stores.
Authorization-cost reductions arise through two mechanisms. First, the network can decline attempts involving a known-compromised or invalid token without sending the credential through the normal account path, reducing unnecessary downstream activity. Second, token-specific controls can make stolen payment credentials less useful, reducing fraud-related authorization retries, chargebacks, and manual reviews. Those mechanisms can lower the cost of authorization processing, but they do not make a percentage claim self-validating: the relevant question is whether the token deployment actually changed the number and cost of attempts.
Merchants should also distinguish the token from the transaction. A token may be linked to a card account, device, or merchant relationship, but it does not itself determine whether a purchase is approved. Issuer rules, account status, merchant activity patterns, and network risk controls still govern the decision. The clean implementation test is simple: a successful authorization should be traceable from the merchant’s token reference to the network’s secure mapping, while the merchant’s stored credential should contain no recoverable primary account number.
The evidence: what is actually measured
The 60% figure should be treated as a claim awaiting substantiation, not as a benchmark established by the available evidence. The first check is whether a source defines “authorization cost” as fees charged per attempt, total processing expense, or a broader operating cost. A percentage is not meaningful unless both the tokenized and non-tokenized sides use the same definition. The available grounding does not include a card-network publication demonstrating a 60% reduction in authorization cost for tokenized transactions, so the figure in the headline is not presently verifiable from the cited evidence.
One hard market figure is available, but its scope is narrow. A LinkedIn article titled “Tokenized RWAs in DeFi Collateralized Lending: A Technical Guide for 2025,” published August 11, 2025, reports that the tokenized real-world asset market expanded to $24 billion as of 2025, with a forecast pointing to a $500 billion valuation by year-end. That figure concerns tokenized real-world assets, not card-network tokens, and therefore cannot substantiate either a card-fraud reduction or a card-authorization-cost reduction. The relevant check is category: the claimed market must involve payment-card tokenization before it can support this argument.
The available sources also provides no card-network-published fraud-loss result comparing tokenized and non-tokenized card transactions. It identifies no period, cohort, transaction count, loss definition, or merchant population from which a fraud improvement could be calculated. Consequently, there is no sourced percentage here for lower card-fraud losses, no baseline loss rate, and no comparable tokenized result. The appropriate rule is simple: a vendor’s general statements about token security are not a measurement of fraud losses unless they are tied to transaction outcomes.
Before accepting the 60% claim, require the vendor to show the number of tokenized and non-tokenized authorization attempts, the approval rate for each group, and the fraud-loss figures for the same merchant over a defined comparison period. Attempt counts establish the scale of the evidence; approval rates show whether tokenization changed the mix of transactions that reached authorization or approval; fraud-loss figures reveal whether the claimed savings were accompanied by a measurable reduction in losses. A lower total charge can otherwise reflect fewer attempts, a different approval mix, or a different observation period rather than lower unit authorization cost.
Finally, require the comparison to use the same merchant, card network, transaction types, and time window, with the same inclusions and exclusions on both sides. A vendor should be able to reproduce the percentage from the displayed underlying counts and amounts. If it cannot, the 60% figure remains marketing language rather than auditable evidence. The $24 billion and $500 billion RWA figures demonstrate that tokenization-related market claims were being published in 2025, but they do not verify the card-fraud or authorization-cost claims at issue here.
Options compared
Choosing among card-data handling approaches requires separating reduced data exposure from actual fraud reduction. A merchant-side vault can make stored card data look less sensitive while leaving the underlying account and network authorization process unchanged. The relevant comparison is therefore not simply which option stores the fewest digits; it is which option measurably reduces losses and authorization costs for the merchant.
Frequently Asked Questions
What evidence is required to verify a vendor’s claim of lower authorization costs?
Verification requires authorization attempt counts and a directly comparable cost delta from tokenized and non-tokenized attempts for the same merchant.
Can lower authorization costs be attributed to tokenization without comparing approval rates?
No, approval rates must be compared before attributing lower cost to tokenization.
Which two approval-rate figures are needed for the same-merchant test?
The test requires tokenized and non-tokenized authorization approval-rate figures from the same merchant and period.
What must be measured in addition to authorization costs to assess tokenization performance?
Tokenized versus non-tokenized fraud-loss performance must be measured alongside authorization costs.
Do the $24 billion tokenized RWA market and $500 billion year-end forecast prove lower card-fraud losses or authorization costs?
No, those market figures do not establish any reduction in card-fraud losses or authorization costs.
Can a network-issued card token be used directly outside the network’s controlled authorization path?
No, the 16-digit network-issued surrogate is not valid for direct use outside the network’s controlled authorization path.
