1. A point of sale device that selectively operates in an unsecure mode of operation and a secure mode of operation, the point of sale device comprising:
an applications microprocessor programmed to generate a set of data packets;
a secure microprocessor communicatively coupled with the applications microprocessor and configured to instantiate a filter, the secure microprocessor covered by a tamper mesh, wherein the filter is configured to (i) filter the set of data packets from the applications microprocessor when operating in the unsecure mode, such that data packets identified as related to payment device communications are prevented from reaching a near field communication front end of the point of sale device, and (ii) allow a subset of the data packets filtered by the filter to pass through based on a whitelist for the filter, wherein the subset of data packets were filtered by the filter in a false-positive filtering event; and
the near field communication front end communicatively coupled with (i) the secure microprocessor, and (ii) an antenna of the point of sale device for transmitting a near field communication signal via the antenna, wherein the near field communication signal is based on information from the subset of data packets,
wherein the unsecure mode is to communicate with a device having non-payment related information and the secure mode is to communicate with a device having payment related information.
