# Card readers > Buy, add and remove card readers, how readers ask for tips, and how to use a Bluetooth reader in the Lilo app. Source: https://heylilo.co/help/payments/card-readers Card readers let clients pay by card in person. Smart readers, like the WisePOS E or S700, each belong to one of your locations. In the Lilo app, you can also use Stripe's M2 Bluetooth reader. **Applies to:** Owners and admins You add and remove smart readers in [**Settings** → **Payments**](https://app.heylilo.co/dashboard/settings?tab=payments). You need card payments active first. See [Connect payments and get paid out](https://heylilo.co/help/payments/connect-payments). ## Buy a reader **Applies to:** Owners and admins 1. Go to **Settings** → **Payments**. 2. In **Terminal Readers**, select **Purchase Reader**. 3. Stripe's reader shop opens in the **Purchase Readers** section. Choose your readers and order them there. ## Add a reader **Applies to:** Owners and admins Turn the reader on and find its registration code. It's three words, like apple-pear-grape. 1. Go to **Settings** → **Payments**. 2. In **Terminal Readers**, select **Add Reader**. 3. In the **Add Terminal Reader** box, stay on **Physical reader**. 4. Choose the **Location** where you'll use the reader. 5. Enter the **Registration code**. 6. Add a **Label (optional)**, like Front desk reader. If you leave it blank, Lilo names the reader after its location. 7. Select **Register reader**. You'll see **Reader registered**. Lilo sets every smart reader up to ask your clients for a tip (see **Tips on smart readers**). ## Remove a reader **Applies to:** Owners and admins 1. Go to **Settings** → **Payments**. 2. In **Terminal Readers**, choose the reader's **Location**. 3. Select the trash can next to the reader. 4. Select **Delete**. You'll see **Reader deleted**. This also removes the reader from your Stripe account. To use it again, follow **Add a reader**. ## Tips on smart readers Smart readers ask your client for a tip before they pay: - Above a small amount, the reader suggests 15%, 20% or 25% of the services. Products don't count. - Below that amount, it suggests a few small fixed amounts instead. Lilo skips the tip question when you've already added a tip at checkout. It also skips it when there's nothing to tip on, like a sale of only products. You can't change these options. [Tips](https://heylilo.co/help/payments/tips) covers every way clients tip. **Applies to:** Owners and admins To see the options, select **Show** next to **Tipping** in **Settings** → **Payments**. ## Use a Bluetooth reader in the app The Lilo app also works with Stripe's M2 Bluetooth reader. You don't add it in Settings. 1. Turn on the M2 and keep it near your phone. 2. In the app, open [checkout](https://heylilo.co/help/payments/checkout) for the appointment and tap **Charge** at the bottom. If the button names your client's saved card, tap **Use a different payment method** instead. 3. Tap **Bluetooth reader**. 4. On **Tip**, choose your client's tip or **No tip**, then tap **Continue**. The M2 has no screen for tips, so you add the tip in the app. 5. The app connects to the reader. Your client pays on it. ## How it works - Each reader belongs to one location. At checkout, **Terminal** shows up when the appointment's location has a reader, and only that location's readers are listed. - **Online** and **Offline** show what Lilo last heard from the reader. Lilo checks every reader once a day, so the status can be out of date. - Readers only work while your card payments are active. - Only the owner and admins can buy, add or remove readers, because only they can open **Settings** → **Payments**. Anyone who takes payments can use a reader at checkout. - You add and remove readers on the web. In the Lilo app, smart readers show up at checkout under **Terminal**. They ask for the tip themselves. **Applies to:** Owners and admins - **Terminal Readers** shows one location's readers at a time. Each reader shows its label, its type and **Online** or **Offline**. - If your card payments are put on hold, **Terminal Readers** is hidden. ## Common questions ### Why does my reader say Offline? Lilo checks readers once a day, so the status can be old. If checkout says **The reader is offline**, check that the reader is on and connected to the internet, then try again. ### Can I change the tip percentages? No. Every smart reader suggests 15%, 20% or 25%, or small fixed amounts on small payments. ### Do I add a Bluetooth reader in Settings? No. In the Lilo app, tap **Bluetooth reader** at checkout. The app connects to the M2 near your phone. ### Why can't I add a reader? **Applies to:** Owners and admins The **Add Terminal Reader** box says what went wrong. Usually it's one of these: - Your card payments aren't active yet. Check **Settings** → **Payments**. - The registration code doesn't match the reader. Check the code on the reader and try again. - The location's address isn't complete. Finish it in **Settings** → **Locations**, then try again. See [Locations](https://heylilo.co/help/settings/locations). ### Can I rename a reader or move it to another location? **Applies to:** Owners and admins No. Remove it, then add it again with the new label or location. ### What's the Simulated tab in Add Reader? **Applies to:** Owners and admins It's for testing without a real reader. Simulated readers only work in test mode, so you can ignore it. ### What if the reader shop says ordering isn't available? **Applies to:** Owners and admins Lilo can't take reader orders right now. Use **Contact support** in your account menu and ask about ordering readers. See [Get help from Lilo](https://heylilo.co/help/account/get-help). ### Why won't the reader shop load? **Applies to:** Owners and admins An ad blocker or privacy extension can block it. If you see **The reader shop was blocked**, allow connect-js.stripe.com or pause the blocker, then select **Reload Page**.
