For deposits and withdrawal of hryvnia to cards p2p payments (simple transfers between cards of individuals) are used.
The hryvnia deposit of one user is frozen until it is used for withdrawal to another user.
Schematically, the work of this mechanism looks like this:
International payment systems Visa/Mastercard together with the National Bank of Ukraine are limiting the use of p2p payments.
The limits correspond to the financial monitoring of Ukraine and the rules of the IPS VISA/MC. Which are:
Per day - up to 150 000 UAH,
Per month - up to 250 000 UAH.
Limits on deposit and withdrawal from the card are summarized and fixed by the issuing bank of the card.
At the fulfillment of limits, banks most often block the possibility of receiving and sending funds from a card. In the personal cabinet of the exchange, this blocking is displayed by rejected transactions of input or output.
To solve the problem, try to use another card for deposit/withdrawal.
If you have a Privat24 - create a virtual Internet card MasterCard and make Deposit/Withdraw with it.
