# Overview

**VGS Show iOS SDK** allows you to securely reveal data for your users without having to have that data pass through your systems. It provides customizable UI elements for showing users' sensitive data securely on iOS devices.

## A note about data security compliance

Companies that store, transmit, or process sensitive card data, including the primary account number (PAN), expiration date, and card verification value (CVV2), must comply with the Payment Card Industry Data Security Standard (PCI DSS).

Achieving PCI DSS certification without Very Good Security is both time consuming and expensive. VGS Show SDK offloads the PCI compliance burden (for certain use cases) by enabling the encrypted transmission of sensitive card data from Very Good Security directly to your cardholder or a PCI compliant processor. Very Good Security is fully PCI-Level 1 compliant and handles sensitive card data transactions for you so that your servers never store, transmit, or process the card data.
