How to Activate the TeleSign Phone Verification:
There is a setting in your Administration Panel under Store Configurations > Shop Parameters labeled TeleSign Customer ID.
When a TeleSign Customer ID is saved, the TeleSign phone verification function is enabled.
It is disabled by leaving the field blank.
* Don't forget to click the "Submit" button to save any changes you make in the Administration Panel.
How TeleSign Phone Verification Works:
In the payment form, if TeleSign is enabled, there is a comment below the phone number field.
When the payment form is submitted, the customer is redirected to a verification page. TeleSign automatically calls the customer's phone number and gives a numeric code, which must then be entered into the verification page and submitted to complete the order.
This system will reduce credit card fraud because thieves are not likely to give up legitimate phone numbers where they can be reached.
** Note
TeleSign Phone Verification works with Payment Gateways, such as these, that use the AShop payment form:
Authorize.Net AIM, Verisign PayFlo Pro, eSelect, Echo, and offline processing.
It does not work with payment options where the payment form is hosted on the processor's server such as:
Authorize.Net SIM and the majority of other payment options.
** TeleSign Phone Verification is not a Payment Gateway in itself, but a tool to help prevent credit card fraud.
