Any money you have in your Amaiz current account or Jar account is kept in a ring-fenced safeguarded account in Barclays. This is a requirement of the FCA's UK Electronic Money Regulations 2011.
Simply put, it means that your funds are kept separate from Amaiz's Balance Sheet and are never lent, reinvested or put at risk otherwise.
Traditional banks pay into the Financial Services Compensation Scheme to compensate the funds you keep with them if they are unable to pay your deposits back. We are not covered by the FSCS because we don't use your money, and they are only accessible by you.
