Pocket EZPIN device for healthcare IC cards to enhance the security and convenience of senior citizens

An application that adopts smart cards often requires users to enter a PIN (Personal Identification Number) code. In Taiwan's healthcare system, a PIN is used to protect a card holder's private data. However, should one forget one's PIN, the procedure to set up a new PIN is inconvenient. There is a higher probability that senior citizens may forget their PINs. We propose a device which stores the PIN of the cardholder's Healthcare IC card. When the healthcare IC card reader requires the cardholder to enter his/her PIN, the cardholder pushes a button of the device to remotely sends the cardholder's encrypted PIN, for example by Infra Red. The device is designed to be low cost and easy to carry, and, hence, affordable to be a gift to senior citizens. Moreover, if the cardholder should forget to take the device with him/her, the card still works as normal. The device would be helpful in ensuring the public's privacy and convenience in Taiwan's healthcare system.
