Auto Signature

Auto Signature is a feature that allows Simplify to automatically prompt for a signature and send a Signature message (Signature Response format) to the POS, without first receiving a Signature Request. (Signature prompt will occur before or after the prompt to remove EMV card, depending on configuration.)

The following transactions are eligible for auto signature: approved Sale, Auth Only and Return transactions on touchscreen PIN Pads. If Auto Signature is supported, all Stand In responses from Simplify must be approved by the POS, as signature processing will occur regardless of the POS decision.

Configuration settings determine whether auto signature will occur for an eligible transaction. However these settings can be overridden by a field in the authorization request. This design provides two ways to trigger an auto signature:

  • Configuration -- Simplify can be configured to perform an auto signature for all transactions that satisfy a configured minimum.

    • This minimum is defined independently for each combination of supported transaction type and tender type. If set to 0, auto signature will be disabled.
  • POS message -- An optional Auto Signature Control field in the authorization request (field 11 bytes 4-5) can be used to force or suppress an auto signature for the transaction, regardless of configuration.

    • The use of the Auto Signature Control field must be enabled. This is controlled by a separate setting that only affects the use of this field. This setting is defined independently for each combination of supported transaction type and tender type.

    • To force an auto signature, send S1 in this field.

    • To suppress auto signature (regardless of configuration) send S0 in this field.

    • If this field is blank, configuration settings will determine whether auto signature processing occurs.

For auto signature-eligible transactions, Simplify will use field 5001 bytes 1-8 in the authorization response to inform the POS whether Simplify is performing auto signature processing for the transaction, as follows:

  • 991002S0 = Simplify will not prompt for signature. It is in CLOSED state

  • 991002S1 = Simplify is asking for signature, wait for Signature Response.

The wording on the auto signature screen can be customized by Elavon. Up to three lines of text can be defined, with a maximum length of 40 characters each. Please contact your Elavon representative regarding your requirements.
