French word "numéro" made Chrome suggest saved credit cards

Developers found that Chrome and Android Autofill ignore autocomplete="off" and classify card fields partly by label text: a "Numéro de commande" field with numeric input was treated as a card number. The workaround inserts an invisible U+200B character inside the label word, leaving the visible text unchanged.

• Chrome deliberately ignores autocomplete="off" for payment fields since 2014
• "Numéro de commande" with inputmode="numeric" and maxlength=9 triggered Google Pay card suggestions
• Splitting the word with U+200B removes the suggestion while text looks identical
• Screen reader impact was not tested; authors call it an open question
