A number of major contractors are looking at the move as the CSCS continues to develop the technology surrounding its smart cards.
Smart cards contain a microchip which stores information on qualifications and training courses.
But CSCS development manager Andy Puttock told the Enquirer that “only a fraction” of the chip’s capacity is being used.
He said: “So much more can be included on the card including developments like loading them-up with money like a pre-paid credit card so sites can become cash free.
“Site staff could then use their cards to buy things in the canteen.
“We are currently speaking to a number of major contractors about initiatives like this.”
