This study integrates the Technology Acceptance Model (TAM) with the Theory of Planned Behavior (TPB) to analyze consumers' decisions to use a Shariah-based e-wallet in Indonesia. With convenience sampling, a hundred samples were calculated by using SEM-PLS analysis. It found that only perceived trust and intention influenced consumers' decisions to use a Shariah-based e-wallet, while perceived ease of use, usefulness, enjoyment, attitude, subjective norm, and perceived behavioral control did not. Perceived ease of use and usefulness influenced consumers' intentions but not the decision to use Sharia-based e-wallets. Thus, intention does not necessarily describe actual behavior. Consumers feel that the Sharia-based e-wallet is not as easy and useful as other e-wallets they mostly use, like Go-pay, Shopee-pay, and OVO. Other implications and some recommendations are discussed further in this study.

In this study, researchers examined how consumer decisions on purchases in e-commerce are particularly influenced by trust, attitudes and the ease of new shopping places. The data collection research was conducted using a questionnaire with 130 consumer respondents who had bought at ecommerce which would later be processed by Amos' Structural Equation Modeling (SEM). The study used four variables, thirteen dimensions and twenty-six indicators. The results showed that trust, convenience and attitudes influenced consumer decisions in buying e-commerce. The results also showed that trust had the greatest and most significant influence on consumer decisions to buy in e-commerce. So, it can be said that consumers buy because it is based on a sense of already trusting an e-commerce to make e-commerce crowded and buyers need to pay attention to improving their taste.
