The Right Amount of Cards, Cash and ID to Carry in Your Wallet

The Right Amount of Cards, Cash and ID to Carry in Your Wallet
Share on FacebookShare on TwitterShare on LinkedIn

April 3, 2023

The Wall Street Journal recently published an article featuring Nina Mazar, Professor of Marketing, discussing the importance of having cash accessible in your wallet.

Technology has been shrinking wallets for centuries. As phones take on the role of wallets, people are rethinking how much they still need to carry in cash, cards, and identification. In a typical week, four out of ten Americans do not use cash for their purchases. Several states, such as Arizona and Georgia, began allowing residents to upload their driver’s licenses or state ID cards to their Apple Wallets in 2021. There is a general trend toward minimalist wallets that contain just a few cards or attach to phones. Many Americans do carry around cash, on average of about $67. Mazar states,

“Paying cash might help curb overspending, however, since the emotional impact of spending bills is greater than paying with a phone or credit card.”

Most Americans have four credit cards, but financial advisers suggest carrying two to three cards at most.

Nina Mazar

Nina Mazar is Professor of Marketing at Boston University Questrom School of Business. With her focus on behavioral science, Nina investigates how expectations, emotions, peers, and random cues in the environment affect how people think about products, money, investments, and morality, and their implications for welfare, development, and policy. Her research topics range from curbing dishonesty to irrational attraction to free products, the paradoxes of green behavior, tax compliance, organ and blood donation, and nudges to reduce credit card delinquency.
