  • Patent number: 11062289
    Abstract: A handheld POS terminal is provided, which is wired to a secure base unit by a cable consisting of two pieces that are joined together by a plug-in connector. The plug-in connector has a pull-out force necessary to separate the connector that is greater than the weight of the POS terminal but less than the force necessary to damage the cable connections at the POS terminal or at the base unit. The cable may also include a coiled section, which acts as a spring, so that if the POS terminal is dropped, the coiled section brings the POS terminal gently to a stop before it hits the ground. If a customer drives away with the POS terminal still in the car, the cable will separate at the plug-in connector, preventing damage to the POS terminal.

  • Publication number: 20130110656
    Abstract: A versatile payment system connected to the payment network for the use with a POS application is disclosed. The payment system can be configured as a stand-alone payment system or a payment system integrated with the POS application. Versatility is achieved by (1) running the service manager in the background, allowing it to communicate with the POS application, (2) providing a setup menu allowing the user to configure its integration with the POS application, and (3) using a simple data-exchanging schema allowing the service manager and the POS application to exchange data such as authorization codes and amount of payment.
