Maryland's move to chip-enabled EBT cards marks another state joining the shift away from magnetic stripe technology. If you've managed similar transitions, you know the announcement is the easy part. The actual deployment is where most programs stumble.
Chip card rollouts often fail. States underestimate cardholder confusion, overestimate merchant readiness, and discover too late that their fraud detection rules don't work with EMV transaction data. These aren't rare occurrences. They're the norm.
Why These Mistakes Keep Happening
State-administered payment programs face different challenges than commercial card issuers. You're deploying to populations with limited access to banking services, merchant networks with outdated terminals, and fraud detection systems built for mag-stripe transactions. The chip technology is proven, but the implementation environment is tough.
Most states also lack dedicated payment security teams. The people managing EBT programs are benefits administrators, not fraud analysts. They inherit payment infrastructure decisions made years ago and don't have the budget to replace everything at once. So they make incremental changes and hope the gaps don't matter.
They do.
Mistake 1: Deploying Without Terminal Readiness Data
Why it happens: States assume merchants will upgrade terminals to accept chip cards because the liability shift happened years ago in the commercial card space. But EBT acceptance is different. Many small retailers still use older point-of-sale systems that technically support EBT but haven't enabled chip reading for government benefit cards.
The consequence: Cardholders receive chip cards but are forced to swipe at checkout. The chip never gets used. You've spent money on more secure cards but haven't reduced your fraud exposure because the transaction still relies on static magnetic stripe data.
The fix: Survey your top merchant locations before you mail a single card. Focus on high-transaction venues: grocery stores in low-income areas, convenience stores near transit hubs, and farmers markets that accept SNAP. Get actual terminal firmware versions and EMV certification status. If more than 15% of your transaction volume flows through merchants without working chip readers, delay the rollout and work with your processor to push terminal upgrades.
Mistake 2: Keeping Mag-Stripe Fraud Rules for Chip Transactions
Why it happens: Your fraud detection system has rules tuned for magnetic stripe transactions. Geographic velocity checks, merchant category code patterns, transaction amount thresholds. When you introduce chip cards, those transactions generate different data elements, but your rules keep running unchanged.
The consequence: You get false positives on legitimate chip transactions and false negatives on actual fraud. Chip transactions include cryptographic validation data that mag-stripe transactions don't have. If you're not checking that the chip cryptogram is valid, you're missing a primary fraud signal. Meanwhile, you're still blocking cardholders for velocity patterns that matter less when the chip proves the card is present.
The fix: Build separate rule sets for chip versus mag-stripe transactions before you issue cards. For chip transactions, prioritize cryptogram validation failures and fallback-to-swipe patterns (where a chip card is suddenly swiped repeatedly). Relax geographic velocity rules for chip-present transactions because the cryptogram proves card presence. For mag-stripe transactions after chip issuance, increase scrutiny because legitimate cardholders should be using the chip.
Mistake 3: Ignoring the Fallback-to-Swipe Attack Vector
Why it happens: Teams focus on the fraud that chip technology prevents (counterfeit cards) but don't consider the fraud it enables. When a merchant terminal can't read a chip, it falls back to the magnetic stripe. Fraudsters exploit this by damaging chips on stolen cards or using terminals they've modified to always fail chip reads.
The consequence: You issue chip cards, declare victory over counterfeit fraud, and then watch your mag-stripe fraud rates hold steady or even increase. The fraudsters adapted. You didn't.
The fix: Monitor fallback rates by merchant and by card. A single card that falls back to swipe repeatedly is either damaged or compromised. A merchant with a high fallback rate either has broken terminals or is colluding with fraudsters. Set thresholds: any card with more than three fallback transactions in 30 days gets reviewed. Any merchant with fallback rates above 5% gets a terminal inspection. Block cards that show fallback patterns combined with geographic anomalies.
Mistake 4: Failing to Educate Cardholders on Chip Use
Why it happens: States assume chip cards are self-explanatory. Insert instead of swipe. But your cardholder population may have limited experience with chip cards, especially if they don't have commercial credit or debit cards. They don't know to leave the card in the terminal or that they need to wait for approval before removing it.
The consequence: Cardholders pull the chip card out too early, causing transaction failures. They get frustrated, start swiping instead, and the chip never gets used. Merchants get annoyed by the delays and tell cardholders to just swipe. Your chip deployment becomes a mag-stripe deployment with more expensive cards.
The fix: Include a visual insert guide with every card. Not a paragraph of text, a diagram showing the chip going into the terminal slot and staying there. Train call center staff on the three most common chip transaction problems: removing card too early, inserting chip-end first but upside down, and trying to swipe a chip card at a chip-enabled terminal. Post signage at high-volume merchants showing proper chip insertion. Consider SMS or IVR messages to new cardholders after their first chip transaction confirming they used it correctly.
Mistake 5: Treating the Chip as Complete Fraud Prevention
Why it happens: Chip technology dramatically reduces counterfeit card fraud. That's real. But states see the reduction in one fraud type and relax monitoring for other attack vectors. The chip doesn't prevent account takeover, lost/stolen card fraud, or card-not-present fraud.
The consequence: Your counterfeit fraud drops, but your overall fraud loss stays flat because other fraud types increase. Fraudsters shift tactics. They stop making fake cards and start stealing real ones, or they move to online benefit transfer fraud if your program allows any card-not-present transactions.
The fix: Decompose your fraud metrics by attack type. Track counterfeit, lost/stolen, account takeover, and card-not-present fraud separately. When you deploy chip cards, you should see counterfeit fraud collapse within 90 days. If your total fraud number doesn't drop proportionally, the fraud is moving somewhere else. Increase monitoring on account changes (address updates, PIN resets) and on the first transaction after a card is reported lost. Chip cards protect the plastic, not the account.
Prevention Checklist
Before you issue chip-enabled cards:
- Verify chip-reading capability at merchants representing 85%+ of transaction volume
- Build chip-specific fraud detection rules that validate cryptograms and flag fallback patterns
- Set fallback-to-swipe monitoring thresholds (card level: 3 in 30 days; merchant level: 5% rate)
- Create cardholder education materials with visual chip insertion guides
- Train call center and merchant support staff on chip transaction troubleshooting
- Establish separate fraud metrics for counterfeit, lost/stolen, and account takeover fraud
- Define your fallback transaction review process and assign staff to execute it
- Test your fraud detection system with sample EMV transaction data before deployment
The chip card rollout isn't the finish line. It's the start of a different fraud management problem. Plan for that reality.
