In order for Surkus to know how much cashback to give, we need to know the amount of the transaction so we can calculate the rewards as they are based on percentage.
Becoming "Verified by Plaid" allows Surkus to store limited personal information in order to validate identity (name, email, address and the last 4 digits of an account). Surkus also stores the information related to the actual transaction used in the verified purchase. Surkus does not store the users' full account numbers, their balance, history, or other financial information. Surkus does not ever see a user’s bank account or credit card info (this is all secured by Plaid).
Plaid is an application development software designed to allow applications to connect with the bank accounts of users, providing them with access to banking data while reducing risk and validating ownership of such accounts. It is used by companies such as Venmo, Robinhood, Coinbase, Betterment, and Acorns, among other secure institutions as a means to verify users’ identities and transactions.
