Stress increases the risk of heart problems and can be a hindrance in daily chores. In this study, we have acquired values using a Galvanic Skin Response (GSR) sensor. GSR is a measurement of ongoing changes in the electrical properties (conductivity) of the skin brought on by variations in the activity of human perspiration. This theory is predicated on the idea that sweat gland activity alters the skin's resistance. Only the resistance was returned in order to calculate the conductivity. We have analysed these values by detecting the level of stress utilizing supervised machine learning algorithms. A person's physiological state can be utilised to determine whether or not they are stressed. They are used to forecast whether a person's stress levels will rise or fall while they carry out activities like exercising or tensing. We have developed a model using a custom-made dataset to detect the stress levels of an individual. The model was tested using multiple classifiers and makes accurate predictions to determine the stress level given a single input value, obtained from the GSR sensor. [ABSTRACT FROM AUTHOR]

In order to accommodate the country's growing population, the number of apartment complexes has increased dramatically. Most new apartment complexes include a variety of modern amenities such as a supermarket, a medical centre, EV charging stations, vending machines, and many more. To use these amenities, we normally need to have a credit or debit card, or even cash on hand. Also, there are numerous identity and government cards that a person must carry with them at all times. Keeping track of all these cards can prove to be quite tedious and time-consuming. Furthermore, the majority of these apartments feature the standard lock and key method of unlocking the doors of the residing occupants which adds to the load of carrying about house keys along with all of the other cards. Life would be so much easier if we could replace all of these numerous bank cards with just one. Using a single card to access all services, such as EV charging or purchasing items, and even as your home door key. With the tap and go feature, the user does not have to pay at the same time but can make a payment all at once when the statement arrives at the end of the month, saving both time and keeping track of all transactions with ease. Hence, we propose in this paper a smart card that uses RFID technology to access all of the many amenities in apartment complexes. [ABSTRACT FROM AUTHOR]
