Abstract: Embodiments provide techniques, including systems and methods, for identifying and matching requestors and providers. For example, embodiments can display an identification pattern that is unique for a matched requestor and provider to allow the providers and requestors to quickly, easily, and accurately validate one another's identities prior to a service being provided. In some embodiments, the identification element may be presented on a provider communication device to clearly display graphics associated with an identification element to all requestors in an area so that the requestors may easily identify a matched provider.
