Shell is also testing attendant hand-held wireless card scanners abroad. Both technologies are intended to add more convenience and security to customer transactions.

Chris Suess, manager of global refueling innovations, said: We want Shell to be the first choice for motorists and we aim to achieve that with operational excellence. That involves having the right people in place, first and foremost; but it also requires keeping stride, if not staying ahead of the curve, where technology is concerned.

The Pay By Touch biometric technology Shell has installed at select Chicagoland stations verifies personal identity using biometrics, the measurement of unique physical and behavioral characteristics. Keeping customers financially secure and on-the-go is part of the customer service models that Shell is researching and testing.
