Wirecard is a bank. With a bank, you are protected under deposit insurance law which across EU is typically 100,000 EUR per person per bank. Anything above that amount is up to courts and creditors to claw back from the mess the bank leaves behind as it crashes and burns.
EMIs, on the other hand, are required to maintain 100% reserves (slightly more, in fact). They cannot use the funds for fractional reserve banking, investments, and so on. If an EMI fails, your funds are safe from︀ other creditors.
