# What other cool stuff can Charge for Stripe do?

Well, we’re glad you asked. Here are a couple of things we think are pretty cool.

Cha-ching: Every time you receive a payment (or payout or new customer, or… check the notifications section for all the options) you’ll hear a wonderful “Cha-ching” sound. It’ll be music to your ears every time you hear it!

Hash: We’re as security-conscious as the next person (probably even moreso), which is why when you tap a card to add the details via NFC, we’ll hash (hide) all the card numbers with the exception of the last few digits. It’s just 1 of the ways we’re trying to keep shoppers and sellers happy and safe.
Have any suggestions for how we could improve Charge for Stripe? We’d love to hear from you [here](https://chargeforstripe.com/contact/).

We also think that [payment requests](/en-au/article/how-can-i-send-a-payment-request-uu54mn/) and [app shortcuts](/en-au/article/how-do-app-shortcuts-work-r76wdk/) are pretty handy too!
