Topping up an account is a two step procedure. First an `approve` transaction for the amount to be topped-up must be sent by the topper to the backing ERC-20 token. Then a topup transaction must be sent to the StatusPay contract. This can be done either by the owner of the wallet or, by knowning the associated Keycard address, by anybody owning the used ERC-20 token (even if they don't have a StatusPay account). During the topup tx the ERC-20 tokens will be transferred to the StatusPay contract and an equivalent credit will be added to the topped account.
