EMV `3-D Secure` 2.0 {#pa2-intro-benefits}
==========================================

To improve the customer experience, a new version of `3-D Secure` was developed. EMV `3-D Secure` 2.x uses a less intrusive process to authenticate a buyer, which provides a better customer experience.  
Enhancements to `3-D Secure` 2.x include:

* More robust device data collection to improve risk analysis by the issuing bank.
* Small screens that pop up on your webpage to avoid full-page redirects.
* SDK version for mobile devices like phones and tablets.
* Streamlined shopping experience.

{#pa2-intro-benefits_ul_uf4_tz2_kxb} On September 25, 2024, support for EMV ` 3-D Secure ` 2.1.0 ended. Merchants and their acquirers must support EMV ` 3-D Secure ` 2.2.0 or a later version before that date so that transactions can continue without any interruption in service. Contact support for additional information on updating your system to use EMV ` 3-D Secure ` 2.2.0.
