Square closed up 5.5% on Monday after Bloomberg News reported the payments company could offer savings and checking accounts in the near future.
The report said a code within a Square app update revealed the company’s plans including details about checking and savings accounts.
The hidden code uses rhetoric that leads Bloomberg to believe Square will offer a 0.5% interest rate for its savings account through 2021.
