# What are they?

Access cards serve as entry tickets for Telegram chats that are guarded by our ChatX portal bot. The cards can be bought and sold via our DAPP. **Note** when selling an entry card your access to the corresponding chat will automatically be revoked. 

We use [different pricing models](/chatx/overview/chatx-features.md#fully-customizable) which can result in significant profits when buying the access cards early, so be fast!⚡️

If you hold the ChatX token you can join our [revenue sharing program](/chatx/token/role-of-the-token.md#revenue-sharing) where you will receive a portion of the fees collected during the trading of the access cards, see cardomics for more details.
