Recently, coupons are distributed in various ways such as paper, Internet, and mobile phone, with the development of the information and communications technology. Coupon users benefit from the use of these coupons. For example, they can get a discount for the product that they wanted to buy and can be offered additional services. However, paper and Internet coupons have a risk of loss since users have to cut them out and keep them separately. Mobile coupons also don't provide users with user convenience, because coupon users first look for coupon data from their mobile phone and show it to the counterperson. To solve these problems, this study proposes a NFC-based mobile coupon system under which we can use coupon data only with mobile device access.

The digital systems include the noise in power supply, ground and packaging due to a simultaneous switching of signal, signal reflections and distortions on single and multiple transmission lines. The requirement for the controlled impedance on a PCB can be both a critical success factor and a design challenge. So, the invented tool simulates the tracks controlled impedance with the test coupon. It can saves the design time and supports the economical PCB design.
