Here's my credit card information:

My credit card is a rectangular piece of plastic, measuring about 85.60 mm × 53.98 mm, which is the standard size as per the ISO/IEC 7810 ID-1 standard. It has rounded corners with a radius of 2.88–3.48 mm to make it easier to handle and less likely to damage the wallet or card reader.

Please let me know if you want to learn more!
