Credit Guard / Electronic accessories

Credit Guard
Credit Guard

Credit Guard is a credit card film reminding people to pay off their debt by color.
Spending future money has become one of our consumption habits, but the use of the credit card often causes forgetting of the overdraft amount and repayment deadline, which leads to the credit crisis.Credit Guard uses photosensitive display medium and Active RFIDI. With the coming of the repayment deadline, it will be changed from blue to red, to remind the user to pay off his debt. At the same time, the film shows the overdraft amount, the repayment deadline and the account name.
Credit Guard will not affect the normal use of the credit card.
