Mastercard Touch Card — Edge Notches Let Blind and Partially Sighted People Tell Card Types Apart by Touch

In October 2021 Mastercard introduced the Touch Card, an accessible card standard for blind and partially sighted people. A notch on the card's short edge identifies the card type by touch: a round notch for credit, a broad squarish notch for debit and a triangular notch for prepaid. The notch also helps users orient the card when inserting it into terminals.
The standard was co-designed with IDEMIA and the concept was vetted and endorsed by the UK's Royal National Institute of Blind People (RNIB) and VISIONS/Services for the Blind and Visually Impaired in the US. It was designed to work with existing point-of-sale terminals and ATMs so that issuers can adopt it without hardware changes.
Evidence caveat: the publicly available material found is the 2021 announcement and trade-press reprints of it. No independent evaluation of user outcomes, adoption numbers or issuer take-up was located, so impact is unproven. It is included as a documented low-cost inclusive-design standard whose benefits rest on user-organisation endorsement rather than measured results.
