In general, a smart card is an integrated circuit card with memory capable of making decisions. A smart card, chip card or integrated circuit card (ICC), is defined as any pocket-sized card with embedded integrated circuits which can process information. In this project, we are using a contact smart card where the information inside the card is communicated with the card reader by inserting card into the card reader. The card reader in this project used is an SR-90 SDK of 1KB memory size. Most of the people, aging around 35 to 45, suffer from few regular problems like arthritis, diabetes, blood pressure etc. These people have to go to the concerned specialists for regular checkups to maintain their health properly. The doctors advise the patients with necessary things to follow and also prescribe with medicines if necessary. The doctor maintains a record of the patient and also suggests the same to the patient. In this process, they provide prescriptions to the patients so as to bring along with them in their next visit. Whenever the patient goes to the doctor for his/her check up, the doctor initially observes the prescription having the details of the patient’s health record and then performs the basic tests like the pulse rate, body temperature of the patient, weight etc. There may be chances that the patient may lose the prescription/reports while going to the doctor. Thus, the doctor has to perform the tests once again on the patient to get the overall idea of the patient’s health. And also, most of the people nowadays prefer cards for everything rather than carrying records, cash with them. Thus, in order to avoid this, we have developed a project called Hospital Management System using Smart card. The patient will be provided with a health card, when he/she sees the doctor for the first time. The health conditions of the patient will be tested and all these details will be saved into his/her health card. When the patient comes to the doctor for his/her review, the patient has to insert the health card into the smart card reader present at the doctor. The parameters pertaining to the patient’s health will be displayed on the LCD. Thus, the doctor after having a glance on these details will perform the tests once again if necessary and these values will be updated into the health card for the next review to the doctor. This project uses regulated 5v, 500mA power supply. 7805 and 7812 three terminal voltage regulators are used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12v step down transformer.
