A birthday card and a very large bunch of candles are due today for the credit card, which is celebrating its 50th anniversary of being introduced to the UK's wallets by Barclaycard.

On 29 June 1966, Barclaycard launched the first credit card with a six-page business strategy, an investment of £20,000 and 30 employees in Northampton.

Within its first year more than a million customers were signed up, although at the time they could only make purchases of up to £25.

"Back in the sixties, cash was the most popular form of payment and the idea of "paying by plastic" was completely alien to most people," Barclaycard chief executive Amer Sajed said.

"But the introduction of credit cards led to a "democratisation of credit" in the UK and kick-started fifty years of great British shopping creating a material shift in how we pay for goods and services."

Five decades on, more than 31m consumers own a credit card and monthly spending exceeds £15bn, according to the UK Cards Association.

The original strip technology on the credit card has now been replaced by both the chip and PIN system and contactless technology, which is now used in an estimated one in seven transactions on contactless-enabled credit and debit cards.
