Appendix A: Quick Chip and M/Chip Fast Support
ID TECH Augusta-series readers are designed to support the Quick Chip and M/Chip Fast EMV modality
when operating in USB-KB mode. This is sometimes referred to as Faster EMV.
Quick Chip and M/Chip Fast is a particular way of doing contact-EMV transactions, designed to shorten
the amount of time the cardholder spends waiting to remove his or her card from the reader. For
most chip cards, the overall "card inserted" time is on the order of 2.0 seconds. (For cards that lack
Payment System Environment capability on the chip, the overall time can be as long as 7.0 seconds,
because communication with the gateway or acquirer may be required before the card can be
removed from the reader. In Quick Chip, this communication can occur after the card is already
removed from the reader.)
Quick Chip and M/Chip Fast is an
online-only
style of interaction, hence it is especially appropriate for
markets that are traditionally online-only, such as the U.S. retail market. It relies on terminal
configuration changes (not kernel changes), and a hard-coded chain of events surrounding Gen AC
requests, to achieve its functional goals. For detailed information about how Quick Chip and M/Chip
Fast works, be sure to consult the U.S. Payments Forum white paper at:

ID TECH's Augusta-series readers offer Faster EMV, or Quick Chip and M/Chip Fast capability, in
conjunction with USB-Keyboard (USB-KB) mode, which is a patent-pending combination that allows
Augusta to provide EMV-readiness in a virtual terminal environment. Combining EMV with Keyboard
Mode means it becomes exceptionally easy for virtual terminals to support contact EMV transactions
in a browser environment.
When a customer presents a card for a Quick Chip and M/Chip Fast transaction, Augusta reads the
card (and carries out all the usual steps of an EMV transaction, except for Issuer Authentication and
the processing of Issuer Scripts; these steps are not done in Quick Chip and M/Chip Fast), and then it
outputs TLV data as
keystrokes
(which is to say, ASCII-renderable hex values) straight to the host
computer. The "keystrokes" will show up in whatever text window (or text field, in a web form)
currently has focus. (The payment application can intercept these keystrokes as needed, to
parse/filter them, insert appropriate values in appropriate form fields, and/or go online for
authorization.)
The following section describes the configuration steps needed to put an Augusta reader into Quick
Chip and M/Chip Fast Mode. Please note that once the reader is in this mode, all EMV transactions will
occur in USB-KB mode using Quick Chip and M/Chip Fast. (MSR transactions will occur in USB-KB mode
as well.) It is possible to switch the reader back to USB-HID mode at any time.

How To Enable Quick Chip and M/Chip Fast Mode
To enable Quick Chip and M/Chip Fast, first ensure that the reader's firmware is at V1.01.003 or
higher. Then perform the following steps.
