A first location identification token is received from a first location transmitting device, while the portable computerized device is within a predetermined distance from a designated location. A second location identification token is received from a second location transmitting device. A current location signature is calculated using the first and second location identification tokens. A previously stored location signature associated with the first and second location identification tokens is obtained from a computer readable storage medium. The current location signature is compared with the previously stored location signature to determine a similarity measure. The location identification tokens and the current location signature are stored in a memory and transmitted to a server. The presence of the portable computerized device at the designated location is verified based on the location identification tokens and the current location signature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for proving physical presence","description":"Methods and systems receive location identification tokens from transmitters using a portable computerized device.
