Abstract
Systems and/or techniques for facilitating relay attack prevention for electronic quick response (QR) codes are provided. In various embodiments, a system can determine a cardinality and a frame rate. In various aspects, the system can transmit a first electronic instruction to a mobile device, which can cause the mobile device to generate a set of interlaced frames having the determined cardinality. In various cases, the set of interlaced frames can respectively correspond to a set of portions of an electronic QR code, such that different frames from the set of interlaced frames depict different portions from the set of portions of the electronic QR code. In various aspects, the first electronic instruction can further cause the mobile device to sequentially render, at the determined frame rate, the set of interlaced frames on an electronic display of the mobile device. In various aspects, this can cause one portion from the set of portions of the electronic QR code to be depicted on the electronic display at a time. In various instances, the system can transmit a second electronic instruction to a point-of-sale device, which can cause the point-of-sale device to reconfigure scanner settings of the point-of-sale device, and which can enable the point-of-sale device to capture the set of interlaced frames sequentially rendered on the electronic display of the mobile device based on the determined cardinality and the determined frame rate.
