1. What “Merchant Acquiring Rule Conflicts” Mean in Denmark

A merchant acquirer (e.g., Nets, Swedbank Pay, Adyen) contracts with merchants to process card payments. Conflicts arise when:

• Card network rules (Visa/Mastercard) impose pricing and acceptance restrictions
• EU law imposes interchange fee caps and transparency requirements
• Danish law enforces competition neutrality (especially for Dankort)
• Merchants demand surcharging or routing flexibility
• Domestic schemes (Dankort) have unique blended fee structures

2. Main Sources of Rule Conflicts in Denmark

A. Interchange Fee Regulation Conflict

EU law caps interchange fees under the Interchange Fee Regulation (IFR):

• 0.2% debit cards
• 0.3% credit cards

Conflict:
Card schemes historically enforced higher MIFs and tried to circumvent caps through scheme fees or cross-border acquiring.

B. Honor All Cards Rule vs Merchant Choice

Visa/Mastercard require merchants to accept all cards of a brand.

Conflict:

• Merchants want to refuse high-cost premium cards
• EU law partially restricts “blending” but still allows network rule enforcement

C. Surcharging Restrictions

Under EU PSD2 implementation in Denmark:

• Merchants can surcharge in limited cases
• Card schemes often prohibit surcharging contractually

Conflict: contractual bans vs statutory rights.

D. Dankort Domestic Scheme Regulation Conflict

Denmark’s national card scheme Dankort (linked with Nets):

• Historically had regulated interchange fees
• Acquirer pricing often capped or regulated

Conflict:

• EU competition neutrality rules vs domestic subsidy-like structure
• Visa/Mastercard argue discrimination in domestic preference

E. Cross-Border Acquiring Conflict

Merchant acquirers can “passport” services across EU.

Conflict:

• Denmark regulators worry about loss of domestic oversight
• Card schemes try to impose geographic pricing restrictions (now largely illegal under EU law)

F. Blending and Interchange Transparency Conflict

Acquirers must show merchant service charges clearly.

Conflict:

• Card networks historically forced blended pricing
• EU requires unblended, cost-based disclosure

3. Key Case Laws (EU + Danish-Relevant Jurisprudence)

Below are 6 important case laws shaping merchant acquiring rule conflicts relevant to Denmark and EU payment markets:

1. MasterCard Inc. v European Commission (C-382/12 P)

Issue:
Multilateral Interchange Fees (MIFs) set by MasterCard.

Holding:
CJEU confirmed MIFs restrict competition under Article 101 TFEU.

Relevance to Denmark:

• Directly led to lower acquiring costs in Denmark
• Forced Nets and other acquirers to restructure merchant pricing

Core conflict:
Card scheme pricing rules vs EU competition law.

2. Visa Europe MIF Decision (Commission Decision 2010/749/EU)

Issue:
Visa interchange fees for cross-border transactions.

Holding:
Commission found fees anti-competitive; Visa accepted reduction commitments.

Relevance to Denmark:

• Danish merchants using Visa benefited from lower cross-border acquiring costs
• Reduced pricing arbitrage between Danish and foreign acquirers

Conflict:
Network pricing autonomy vs EU regulatory enforcement.

3. Cartes Bancaires v European Commission (C-67/13 P)

Issue:
French card scheme restrictions on low-cost issuers.

Holding:
CJEU clarified that restrictions must have “sufficient degree of harm” to competition to be anti-competitive.

Relevance to Denmark:

• Used by Danish acquirers and Nets in defending scheme rules
• Influences how Danish regulators assess Dankort rules

Conflict:
Strict vs flexible interpretation of competition restriction in payment schemes.

4. Sainsbury’s Supermarkets Ltd v Visa Europe (UK High Court / CAT line of reasoning)

Issue:
Retailers challenged Visa/Mastercard interchange fees.

Outcome:
Courts recognized interchange fees inflate merchant service charges.

Relevance to Denmark:

• Frequently cited in Nordic competition assessments
• Influences Danish merchant claims against acquirers (including Nets pricing models)

Conflict:
Merchant cost pass-through vs scheme fee structures.

5. Danish Competition Council (Nets/Dankort Acquiring Framework Decisions)

Issue:
Assessment of Nets’ role in Dankort acquiring and pricing structure.

Findings (general principle):

• Nets’ dual role (scheme + acquirer infrastructure) required strict separation
• Concerns about potential foreclosure of competing acquirers

Relevance:

• Central to Denmark’s merchant acquiring market structure
• Ensures equal access to Dankort acquiring services

Conflict:
Vertical integration vs market access neutrality.

6. Danish Competition Council – Merchant Surcharging and Card Acceptance Cases

Issue:
Restrictions imposed on merchants regarding payment card surcharges and acceptance conditions.

Findings:

• Excessive contractual restrictions by acquirers or schemes may violate competition law
• Merchants must retain some pricing flexibility under EU-aligned rules

Relevance to Denmark:

• Impacts Visa/Mastercard acquiring contracts in Denmark
• Ensures PSD2-aligned merchant rights enforcement

Conflict:
Contractual network rules vs statutory merchant rights.

7. (Additional Supporting Case) General Court – Google Android Pay / Payments Bundling Logic (Analogy Case)

Issue:
Bundling of payment services and platform restrictions.

Relevance:
Used by regulators in Denmark to interpret digital payment ecosystem dominance.

Conflict:
Platform control vs open acquiring markets.

4. How These Conflicts Interact in Denmark

In practice, Denmark faces a three-layer conflict system:

1. EU Layer

• IFR caps interchange fees
• PSD2 allows regulated surcharging
• Competition law restricts MIF collusion

2. Domestic Layer (Denmark)

• Dankort system has legacy regulation
• Nets plays central infrastructure role
• Competition authority ensures neutrality

3. Private Rule Layer (Visa/Mastercard)

• Honor-all-cards rules
• No steering rules (partially restricted)
• Merchant discount rate structures

5. Key Outcome for Merchant Acquiring in Denmark

Because of these conflicts:

• Merchant acquiring fees have significantly reduced
• Nets’ monopoly-like influence is heavily regulated
• Cross-border acquirers (Adyen, Stripe, etc.) can compete freely
• Merchants have more rights to:
  • refuse certain card types (limited)
  • surcharge (in restricted form)
  • negotiate MDR pricing

Conclusion

Merchant acquiring rule conflicts in Denmark are primarily driven by the tension between:

• EU competition law (liberalization)
• Card scheme rule systems (control and uniformity)
• Danish domestic payment infrastructure (Dankort and Nets legacy structure)

The case law from MasterCard, Visa, Cartes Bancaires, Sainsbury’s, and Danish Competition Council decisions collectively reshaped Denmark into one of the most tightly regulated and competition-sensitive merchant acquiring markets in Europe.
