Position-Preserving Tokenization

The alphabetic and numeric positions in the position-preserving tokenized value matches the alphabetic and numeric positions in the input value.

You can specify the position-preserving tokenization option when using the SLT_2_3 tokenizer and Alpha-Numeric (0-9, a-z, A-Z) token type only.
If you are selecting the Preserve Case or Preserve Position property, then the following additional properties are set:

• The Preserve Length property is enabled and Allow Short Data property is set to Yes, by default. These two properties are not modifiable.
• The retention of characters or digits from the left and the right are disabled, by default. The From Left and From Right properties are both set to zero.

For more information about specifying the position-preserving tokenization option for the Alpha-Numeric (0-9, a-z, A-Z) token type, refer to Create Token Data Elements.

The following table provides some examples for the position-preserving tokenization option.
