Point of Service Entry Mode

Security Categorization

Transaction security depends heavily on the physical or digital presence of the payment card during processing. Chip insertions and contactless taps provide cryptographic proof of the card’s authenticity, making them highly secure. In contrast, manual key entry lacks physical validation and is categorized as a high-risk transaction.

Card networks monitor the proportion of manually entered transactions to detect potential terminal tampering or merchant fraud.

Interchange Differentiation

Different entry methods correspond to distinct fee tiers within the network fee schedules. When a merchant uses chip or contactless terminals, they qualify for the lowest interchange rates because the risk of fraud is minimal. If a transaction is instead run as a fallback swipe or a manual entry, the transaction is processed at a higher, more expensive rate.

This rate hike compensates the network for the increased likelihood of chargebacks and unauthorized transactions. For example, a business that frequently keys in card details can see its processing fees increase by more than one percent per transaction, eroding its operating margin. Retailers must configure their terminals to reject riskier entry modes whenever possible to prevent these avoidable expenses.

Liability Transition

The selected data capture method also determines which party bears the financial burden of subsequent fraud losses. Under network rules, merchants who fail to use the most secure available entry mode assume full liability for any resulting disputes. Upgrading to card-present processing systems shields the merchant from dispute costs.

A merchant who maintains secure entry procedures protects their business from sudden fraud write-offs.
