Card Readers (3 of 7)

Issue: Users lacking fine motor control may have difficultly aligning and inserting a card.

A swipe-style card reader on a kiosk is shown.  The card slot is simply a vertical groove running down the machine, with no features to help guide the card into the slot.

Precisely aligning a card with a card reader slot for insertion or swiping can be difficult for users lacking fine motor control.

Populations Impacted: Users with upper mobility impairments.

Potential Solutions:
  • Design the card slot so that it guides the card into the slot. A slot design with an opening that tapers into the insertion slot or a design that provides a clear area for the user to rest the card before sliding or inserting it reduces the amount of fine motor control required to interact with a card reader.

  • A swipe-style card reader on a kiosk is shown.  There is an opening at the top of the card slot into which users can easily place their cards, and a stop that helps ensure that the card is positioned properly before being swiped.
  • Provide a clear area around the card slot for users to brace their hands. Providing a space near the card slot where users can brace their hands to steady themselves and reduce tremors can help users perform actions more accurately.

  • Provide support for contactless card reading. Contactless cards (which use barcodes or RFID technology to store data) eliminate the need for the user to align and insert the card.
