1. An apparatus for facilitating tactile identification of a document attribute, comprising:
- a document, wherein the document has a set of document attributes;
an electrorheological fluid incorporated within the document at a designated location associated with a document attribute in the set of document attributes, and wherein the electrorheological fluid changes rigidity in a presence of an electric field to facilitate tactile identification of the document attribute;
a base unit externally located from the document, wherein the base unit serves a first pole for the electric field; and
an amplifier externally located from the document, wherein the amplifier serves as a second pole for the electric field.
