There is a standard (and standardised – ISO 7811 & ISO 1073 – I think) font embossed on most (if not all) major credit cards (Visa, Mastercard, Amex, Discover, etc.). It’s designed to be easily transferable between mediums while maintaining legibility, kind of like a typewriter: carved, moulded, punched, pressed, stamped, printed, traced, etched, embossed, etc. It’s also designed to be easily discernable, tangibly by the blind, and optically for computer recognition. Credit Card is an all capitals font for simulating bank cards. Capital letters are positioned at the uppercase keystrokes as expected. The number keys produce the bigger, squarer digits of the 16 figure card number. There is no lowercase to this font. Instead, the small numerals used for validity dates fill the lowercase letter keys, 1 > 9 being at a > i. As on actual credit cards, principal glyphs are monospaced with no pair kerning, and many accented letters are reduced in vertical size to help accommodate the diacritic.
