Beacon과 NFC를 활용하여 '로데오 거리', '가로수길' 등 상가들이 밀집해 있고 이용인구가 많은 곳에서 더욱 효과적으로 거리 내에 있는 인프라들을 이용할 수 있게 하고, 상권 방문자가 쉽게 길을 찾을 수 있도록 하기 위한 서비스이다. NFC 태그를 이용해서 각 점포에 예약을 할 수 있고, Beacon을 통해 방문자의 현재 위치를 파악, 원하는 점포들을 쉽게 찾을 수 있게 하고, 각 점포마다 진행되는 이벤트들을 한 눈으로 파악할 수 있게 하여 상대적으로 적은 마케팅비용으로 더 나은 소비효과를 바라볼 수 있게 한다.

The exposed rocks in the Zacatecas state include mainly Mesozoic sedimentary and volcanic, Cenozoic volcanic and plutonic rocks. Paleozoic metamorphic rocks found in the northwestern portion of the state are considered as the most ancient rocks. These rocks correspond to the Caopas Formation which underlays the Later Paleozoic Rodeo Formation. The Mesozoic sequences are represented by a marine sedimentary sequence of the Later Triassic and the red beds of the Triassic-Jurassic Nazas Formation. The marine sediments of the Upper Jurassic overlay the Nazas Formation or metamorphic rocks from the Paleozoic. The Cretaceous sequences comprises marine sedimentary rocks in the north and northeast, and a volcanosedimentary set in the center and southeast. The Cenozoic is represented by volcanic nondifferentiated rocks, intrusive igneous rocks of acid and intermediate composition, and continental conglomerates with evaporitic sediments. The Quarternary sequences includes basalts, piedmont deposits, alluviums and occasionally, layers of evaporites and saltpeter. Furthermore, a great diversity of mineral deposits of both metallic and nonmetallic types occur in Zacatecas state. The rocks composing these deposits are extremely varied and include formations from Paleozoic to Tertiary. The mineralization age of ore deposits corresponds to the Tertiary in approximately 90%, and their genesis is mainly considered as epigenetic.
