Re: Online buying is sometimes not much better...
"A credit card or payment method should be requested only at the time I have decided to purchase goods or services, and only saved as necessary for processing the transaction."
Indeed. Fortunately, there is a good number of retailers, who do not save full card information. They authenticate the current transaction right away, and if it passes, they'll retain only last 4 digits from the card number for reference. Just like a long-standing practice with printed receipts - only a card issuer and last 4 digits can be seen there.
