Abstract

This invention is a contactless label chipcard including payment and identification information and a check-out system including a contactless reader for reading and updating payment information stored in that label chipcard. The contactless label chipcard is attached to a product, and the system further includes a device for reading and initiating updating of the payment status resident on the chipcard. The device includes the contactless reader for reading information stored in the contactless label chipcard, and a component for generating an invoice based on the information received from the contactless label chipcard. Further, the device includes a component for checking payment of the invoice and a component for initiating update of the payment status. Corresponding methods and computer program products are also provided.

Claims
