Simply pair the device with a smartphone or tablet, and you can accept chip, swipe, and contactless payments in seconds.

What About High-Risk Merchant Accounts?

Some industries—like travel, gaming, CBD, or subscription services—fall into the high-risk merchant category due to higher chargeback rates or compliance complexities. Traditional banks often reject these businesses, but many mobile and portable card machine providers now cater to this segment.

If your business falls under high-risk classification:

·         Choose providers that specialize in high-risk accounts, such as PaymentCloud or Durango Merchant Services.

·         Ensure transparent pricing—watch for hidden setup or rolling reserve fees.

·         Look for fraud prevention tools, chargeback protection, and PCI compliance.

Having the right mobile card machine for small business ensures smoother approvals and fewer transaction disruptions.

Key Factors to Consider Before Buying

When comparing mobile card machines, consider these factors to make a smart decision:

1.      Transaction Fees:
Compare per-swipe or percentage-based fees—these can significantly affect profits.

2.      Connectivity & Battery Life:
Choose a device that works well in your environment (Wi-Fi or mobile data).

3.      Payment Types:
Support for EMV chip, magnetic stripe, NFC (contactless), and mobile wallets (Apple Pay, Google Pay).

4.      Integration:
If you use accounting or POS software, check for compatibility.

5.      Customer Support:
Access to 24/7 help is crucial, especially if you rely on the device for daily operations.

6.      Security:
Ensure PCI DSS compliance, encryption, and fraud detection features.
