Abstract
Official abstract text for this publication.
A method, a portable data storage medium, an approval apparatus and a system for approving a transaction using acceleration sensors integrated in a portable data storage medium.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for releasing a transaction between a portable data carrier and an end device, the method comprising the steps: a) bringing the portable data carrier into an electromagnetic field generated by the end device and drawing power by the data carrier from the electromagnetic field for the power supply of the data carrier, b) exciting the portable data carrier by mechanical oscillation generated by the end device, wherein the end device generates…
