once upon a time 99Pay, a digital wallet that allowed paying bills with a credit card without fees, which is a paradise for those who accumulate miles. The service began to be gradually limited with charges for payments of common boletos, but consumer bills remained exempt. Not anymore: the fintech of the racing app started charging fees for this category.
In a statement sent via email to customers, 99 informed that it will apply to 3.99% fee for payments of consumption slips with a credit card from December 5, 2022. Until then, this type of account (slips with a bar code starting with the number 8) were exempt on the platform.
Previously, with the fee exemption, it was possible to pay water, electricity, taxes, telephone and internet bills by credit card. 99Pay was a great ally of those accumulate points on your credit cardsince it was possible to earn miles with everyday payments.

With the new fees for using a credit card, many users no longer find any sense in using 99Pay. The digital wallet continues without fees for payments with the account balance, but this is not a big differential, since any digital account It works with the same mechanics.
One of the remaining advantages of 99Pay is the return on the balance at 220% of the CDI, but this rate is only applied to applications of up to R$500; amounts exceeding this amount will yield 100% of the CDI. In addition, the digital wallet promises 1% cashback on payment slips, but limited to R$ 5 and only for two slips per month.
It was good while it lasted.
With the application of the 3.99% rate, 99Pay is no longer advantageous for paying consumer bills on credit. If you still want to use the card to make this type of payment, check out RecargaPay.
Currently, RecargaPay charges a fee of 1.99% for payment of consumption slips by credit card; if you subscribe to the Prime+ plan, which costs BRL 19.99 per month, the percentage will be reduced to 1.49%. It will hardly be advantageous to pay these rates to accumulate points or miles.
The fees above are only valid for consumer accounts, that is, those slips that begin with the number 8. For other types of slips, RecargaPay charges up to 4.99% per transaction.
