JPMorgan Chase Bank is making a change to its Zelle policy, blocking payments “originating from contact made through social media…and/or social media messaging apps.”

While a convenient way to send payments from one bank account to another, Zelle scams have been on the rise. In fact, according to the bank, “nearly 50% of scams reported to Chase originate on social media,” with many of these being Zelle scams.

As a result, Chase says it is taking action to crack down on those scams:

Alert, coming soon: For your protection, Chase will not allow you to send Zelle® payments identified as originating from contact through social media

The company explains further in its Zelle Service Agreement and Privacy Notice:

As a recipient or sender of any transfer using the Service, you acknowledge and agree that we may, in our discretion, (A) delay, block or cancel a payment, (B) put a hold on the amount of such payment to or from the Pay From Account or other account (as permitted by applicable law), or (C), charge back and/or claim a refund from you for the amount of such payment, for various reasons including, but not limited to, fraud, scams, suspicious or illegal activity, ineligible or improper payment, payment does not comply with our policies, network rules or terms of service, duplicate payment, incorrect payment (amount or recipient), or otherwise to meet our regulatory, network or other legal obligations. This may include, but is not limited to, payments identified as originating from contact made through social media, social media marketplaces, and/or social media messaging apps. For example, we may delay or hold your payment if we need additional time to verify your identity, the identity of the person sending or receiving the money, or details about the payment, or the payment may be delayed or held due to technical difficulties or circumstances beyond our control. If we delay or block a payment that you have initiated, we will notify you in your account online and/or through email or text message.

Chase’s measures illustrate the growing challenges involved in keeping consumers safe when non-traditional financial apps are in play.
