Technologies We Use





We are experts on RFID, NFC and mobility technologies.


Our company, eSmart Source, Inc. was founded in 1999 with a mission to provide technical services. Industry veteran and CEO Sanjiv Dua joined the company in 2002 and the following year, eSmart Source diversified and began providing training, products and services into the newly emerging RFID (Radio Frequency Identification) field under the name RFID4U. As the industry grew and matured, our main focus shifted from RFID training to software development and automatic identification system implementations, which became our core business.
