how to import private key without scaning QR code I bought Bitcoins from the ATM and it gave me a receipt with a QR code.
and now after one year i wanted to scan it into my wallet, but ink on paper faded and it can`t be scaned.....
so im wondering if i can enter the private key manualy by keyboard?
Your QR code contains your private key, but yes you can recover with the private key directly if the QR code is now physically damaged.

I do not see that option for blockchain.info (which you stated you are trying to use in your comment):

https://blockchain.info/wallet/import-wallet supports QR codes Bitcoin-Qt (wallet.dat) and blockchain.info (wallet.aes.json) files. 

Try one these methods instead (or choose another wallet which you prefer):
