Where is my sensitive data stored?

All payment information is stored with the Bank/ISO in an encrypted vault and is never sent to the terminal. We use tokenization to protect your sensitive data and retrieve payment information without exposing or sending credit card numbers. Your biometric data and profile data are encrypted using a private key and stored on separate, secure Amazon cloud servers using SSL and AES-256 bit encryption.

Who has access to my sensitive data?

We take privacy very seriously. No sensitive profile information will ever be shared with any other user or merchant without explicitly opting in. Merchants will only have access to transactions that took place in their stores, and includes necessary relevant info such as payment method (last 4 digits of credit card), transaction time and date, etc.
