One card / electric credit card

One card
One card

”One card” is a versatile electric card that has many benefits. One of them is saving of plastic and
paper garbage, and another one is safety. There are various cards like credit cards, identity cards and
many membership cards and these are thrown out after using of a while . It causes global warming by
the lack of wood for paper matrials and plastic waste. Used cards and paper receipts are generally
dumped without any recycle in life. Also used receipts that dumped carelessly anywhere bring many
identity thefts. So, I try to solve these problems with LCD and USB on the card .
