Francis Fong Po-kiu, honorary president of the Information Technology Federation, said the near field communication (NFC) chip in older versions of contactless credit cards often contained all three pieces of information needed for making online purchases – the cardholder’s name, card number and expiry date.
“If you did not have all three, you couldn’t make any online transaction,” said Fong.
In most contactless credit cards issued recently, the cardholder’s name has been removed from the NFC chip, which explains why not all banks in Hong Kong that issue contactless credit cards have the security flaw.
Similar measures had been taken in the United States where the problem, known as “electronic pickpocketing”, was first exposed in 2013, Fong said.
(N.B.: It is about when NFC card was issued, not the chip)
