Square Contactless + Chip Reader FAQs

Why doesn’t the Reader connect wirelessly with my iPad 2?

The reader connects wirelessly with the iPad 3 or higher. If you have an iPad 2 with a Square Stand, you can connect the reader directly to the Stand’s hardware hub via USB.

The USB hub on my Square Stand is full. Can I use a splitter to connect my reader?

We don’t officially support splitters or third-party USB hubs, but you can connect the reader wirelessly to your iPad via Bluetooth Low Energy.

Can I use the contactless and chip card Reader in Offline Mode?

No, Offline Mode supports magstripe payments only, so you’ll need to use the magstripe reader or the Square Stand.

Why does my Reader disconnect when I turn on Airplane Mode?

Airplane Mode disables Bluetooth on your device. Which causes your reader will disconnect. Once you go into Airplane Mode, connect your Bluetooth back on to be able to use your reader.
In case you are looking to take magstripe payments while in Offline Mode, disable Wi-Fi only and you will maintain your Bluetooth connection.

Why does my app say “Account Ineligible” when connecting my reader?

Square hardware can only be used in the country where it was originally purchased. If you see Account Ineligible, your reader may have been purchased in a different country.

When will I receive my Square reader?

Once you place an order, your reader will arrive in 5 to 7 business days. When your reader is shipped, you’ll receive an email with tracking information to follow your order.

What is the liability shift and why do I need to accept chip cards?

A detailed overview on the liability shift and what it means for your business can be found in Square’s liability shift guide.

Note: If your customer is not physically present, use Square Invoices or Virtual Terminal to process their payment rather than keying in their card information through the Square app.

Order Questions

Are discounts offered for the reader?

At the moment, discounts aren’t available for the contactless and chip reader, but you can pay for the reader in weekly installments instead of a one-time charge with Square’s hardware installment plan. Learn more about the installment plan.

Device Compatibility Questions

My device doesn’t support BLE. Can I use the reader?

Devices without BLE aren’t currently supported with the contactless and chip reader. 

What if I already have a Square chip card reader?

You can continue to use your chip card reader, but you won’t be able to use the contactless and chip reader at the same time, as they don’t work together. To process magstripe cards, you can use the Square magstripe reader alongside your contactless and chip reader.

Can I connect my reader to multiple devices at the same time? 

The reader can be used with multiple devices, but it only connects with one device at a time. To connect your reader to another device, make sure to disconnect it from its current device. To do so, visit your in-app Settings > tap Card Readers > select your reader from the list > tap “Forget this Reader.”
You can also disconnect the reader by holding down the button on the reader for 20 seconds, until the red lights stop flashing.

Can I use this reader if my business is mobile?

Yes, just make sure you have a strong Wi-Fi or cellular data connection to process payments and that your reader is fully charged before use. 

Can I use any USB cable to charge the reader?

Yes, you can use any standard micro-USB to USB cable, but the reader comes with one for this purpose. 

Settings and Pairing Questions

How do I connect the reader to my mobile device?

You can connect your reader wirelessly or by using the included USB cable to plug directly into the hardware hub of the Square Stand. Keep in mind your device needs to have an internet connection to pair your reader, you are unable to use your reader in Offline Mode.

How do I connect my reader to a new device?

You can connect your reader to any device that supports BLE bluetooth connections. Remember, you’ll need to forget the reader from your old device before you attempt to pair your reader with a new device. If you have any trouble connecting your reader to a new device, check out our troubleshooting steps.

I’d like to connect my reader to the hardware hub of my Square Stand, but the three USB hubs are being used by other devices. Can I use a splitter?

We don’t officially support splitters or third-party USB hubs. We recommend connecting the reader wirelessly to your iPad via Bluetooth LE.  
Note: The iPad 2 doesn’t Support Bluetooth LE, so If you’re using Square Stand with the iPad 2, you’ll need to connect your reader via USB.

How do I turn the reader on and off?

To power it on, push the button on the reader. Once it’s on, you don’t need to worry about turning off the reader. The reader will automatically go into the appropriate mode when not in use to save battery.

Payment Questions

How do I take a contactless payment?

It’s easy! Watch this video to learn how:

What are contactless payments, and how are they different from NFC?

Contactless payments describe the act of paying without touching anything. NFC (Near-Field Communications) is a technology that allows for contactless payments. Using radio frequency, NFC allows devices (e.g. smartphones) to wirelessly communicate at close range to do things like process payments. Apple Pay and Android Pay are both forms of NFC and types of contactless payments.

Are contactless payments secure?

Yes, they’re just as secure as accepting chip cards. In some cases because of additional verification methods (like Touch ID with Apple Pay), contactless payments can be even more secure. Learn more in Square’s comprehensive guide to Apple Pay.

How long does it take to process a chip card?

Chip card payments require additional security steps to transfer and verify chip data. It takes around 2 seconds to complete a chip card transaction when it’s inserted into the reader’s EMV card slot.

Do I leave the chip card in the reader’s chip card slot while taking a payment?

Yes, you’ll need to leave the chip card in the reader until the transaction is complete. You’ll get a confirmation message in the app and see 4 green lights on your reader when it’s time to remove the card.

Can I take test contactless payments with the reader?

Not currently, but you can practice taking contactless payments by completing a $1 sale and immediately processing a refund.

Can I use the reader while my mobile device is connected to other Bluetooth devices?

Yes, you can connect to other devices without impacting your connection to the Square contactless and chip reader.
