Shopping Cart Chip (Credit Card format)

thingiverse

I created this because I use one of these card holders but sometimes need a shopping cart chip. So I made this shopping cart chip in the size of a credit card. The chip has a diameter of about 24 millimeters, roughly the same as a 50-cent coin, and is 1.3 millimeters thick. I revised the shopping cart Chip recently. Now its corners are more like those of a real credit card, and it sits higher so that it's the same height as a regular card. I also added a new version that's 2 millimeters thick for extra durability.
