Paisley-born James Goodfellow will attend the PYMNTS Innovator Awards Dinner, a web company set up to encourage initiatives that shape the future of commerce.
Mr Goodfellow, now 75, came up with the PIN concept in 1965, the idea of four digit banking codes and the digital key pad now used in banks and shops around the world.
His invention led to the automated teller machines (ATMs) which we all use today.
He didn't become rich, despite inventing a system that was to change the face of world banking.
His employers Kelvin Hughes owned the patent, and Mr Goodfellow received just £10 for his brainwave.
But now he is to be recognised at Harvard, in the presence of billionaire businessman Warren Buffet and former US Vice President, Al Gore.
Mr Goodfellow said: "It's a great honour.
"It's nice to get this sort of recognition and to sit amongst such important people.
"PIN technology has changed the face of how we all bank and it's a delight to know what I achieved has been recognised."
Mr Goodfellow's invention made countless millions for others.
He said: "I went on to work for IBM who wanted to license it and offered seven figures.
"NCR fought a law suit in the US and infringement of the PIN copyright cost them $35m in 1982."
The 75 year-old invented his PIN card and came up with the '3 x 3 Plus One' design layout of the digital key pad – which is today's configuration.
He said: "I'm pleased to have come up with this layout which limits shoulder surfing.
"But what does get me worked up is Barclays Bank paid 428 employees £1m each in bonuses.
"Banks such as RBS argue you have to pay top rates to attract top talent, but this isn't top talent. This is reward for failure."
Ironically, James Goodfellow, widely acknowledged as the inventor of Automatic Teller Machine (ATM) technology, believes he has been partly responsible for the problems of modern-day banking.
He said: "PIN technology changed the nature of banking, freeing up banks to have more time to gamble with investor's money.
"And that's what it is. Gambling. They lose, and we have to pay. But who said the world was fair?"
James Goodfellow, did not reveal his contribution to banking technology for 40 years.
But when he did he came under criticism from those who suggest he didn't invent the complete article; his PIN cards did not have a magnetic strip.
He said: "It's true, but I came up with PIN in the days before banking computers, in a time of clerks with ledgers working in hallowed halls.
"And can you say the Wright Brothers didn't invent aeroplanes because their plane didn't have a jet engine?"
David Evans, Chairman of the Payments Hall of Fame 2013 Nomination Process praised the four inductees to the Payments Hall of Fame,
He said: "The four made revolutionary contributions to how consumers and merchants transact with each other and changed the face of payments around the globe."
