Pattern Lock Card / Credit Card

Pattern Lock Card
Pattern Lock Card

Nowadays, people use more credit cards than cashes. As payment is more convenient, it's weak for security.

Also, there are abuses caused by accidents such as theft, loss, etc. To solve the problem, I added the function of pattern lock to the card during the payment of credit card so as to prevent indiscriminate using and consider the safety of credit information during the theft or loss.

In the card including pattern lock system, pattern part is bulging so as to cognize with tactile sense in dark environment or situation which can secure the sights. When succeeding in inputting pattern, it's unlocked and card cannot be used.
