Do you think credit/debit cards will still be a thing after the launch of CBDCs? If not, why? Will payment processors like PayPal, Visa, and Mastercard survive? Your input would be greatly appreciated. Thank you. 
Already the use of credit/debit cards have already reduced since mobile apps banking platforms have been put in place such that everyone can use their mobile phones to makes purchases of goods and other items but there are still payments that requires this credit/debit cards to authenticate payments however this medium of payments have a credit and debit limit which can be frustrating when you want to make large payments or withdrawal that is why Bitcoin will be the end of this debit/credit card because it has not credit limit or withdrawal limit.
The origination of this CBDC has already reduced the total usage of plastic cards.The traditional banking systems are the ones that promotes and distributes physical cards and they are committed to issuing the cards to customers so long as their banking systems continues to operate in Progress.
Card use might continue to fall,irrespective of the fact that some people are still comfortable with using it.But cryptocurrencies is currently leading with the transformation that it offers to financial technology.
