San Francisco police are stepping up efforts to protect residents from cryptocurrency ATM scams by posting warning signs near these machines. The new signs alert users to the risks of fraud and remind them that transactions made through crypto ATMs are often irreversible. Scammers frequently target seniors and vulnerable individuals, tricking them into sending large sums of cash to digital wallets under false pretenses—such as impersonating law enforcement, tech support, or even family members in distress.

Crypto ATMs, which allow users to buy digital currencies with cash, have become popular due to their convenience and privacy. However, their lack of strict identification requirements makes them attractive tools for criminals. Unlike traditional banks or online exchanges, most crypto ATMs do not require extensive verification, allowing scammers to quickly convert stolen money into cryptocurrency and move it overseas.

The San Francisco Police Department hopes these visible warnings will help educate the public and reduce the number of victims. Authorities urge people to be cautious when using crypto ATMs and to never send money to someone they haven’t met in person or who pressures them to act quickly. If something feels suspicious, residents are encouraged to stop the transaction and seek advice from trusted sources.

As more states introduce regulations—such as requiring refunds for fraudulent transactions and limiting daily purchase amounts—local law enforcement continues to play a key role in raising awareness and protecting communities from evolving financial scams.
