Executive Summary
?
Contactless cards are a key technology for improving the consumer experience
for retail transactions. Both computational speed and RF sensitivity are factored
into the consumer’s perceived transaction time. So a balance between speed
and energy efficiency (a.k.a. sensitivity) is required in the chip design. The
sensitivity of the contactless card is a more important metric than the
computational speed, but the implementation of both translates into a better,
overall user experience.? Implementing a highly sensitive solution equates to a
larger read zone and provides more time for the contactless card and the reader
to complete a transaction while the card is in motion. The larger read zone
means there is less hunting for the sweet spot on the reader. TI has a series of
contactless payment products designed specifically to offer high sensitivity and
enable custom, small form factor payment devices beyond cards.? Ultimately, this
results in putting an evolutionary form of payment in the consumers’ hands.
