SpeedLine MobilePay gives your customers added convenience and payment security, while at the same time saving you money. Because the customer pays in person, you pay lower card-present processing fees and reduce liability for fraudulent chargebacks. The mobile card reader uses EMV chip technology, which prevents counterfeit fraud and better protects your customers' card information. Take secure card payments at the customer's door, at the table, or curbside. Depending on order volume, with SpeedLine MobilePay, a restaurant with delivery could save hundreds of dollars every month in reduced card processing rates. The savings apply even to e-commerce orders. When used with a compatible e-commerce system such as SpeedDine, online order payments for the order types you choose are processed at the customer's location, at the same lower card-present rates. With online ordering representing a growing percentage of many operations’ sales, that means significant savings and risk reduction. Features: • Scans a QR code for fast auto-fill of payment amount and ticket number. • An inexpensive mobile EMV payment device allows tap payments, Apple Pay, Google Pay, and easy driver tipping. • Accepts multiple payments. • Validated against the current version of PCI DSS for compliance. • Customer payment card details are encrypted and tokenized at the door, and EMV employed for optimal payment security and fraud protection. • Accepts multiple payments. • "Store and Forward" mode securely stores payment information in case of lost cell reception.
