Zusammenfassung:	Systems, methods, and devices for detection of a substance on the surface of an object are disclosed. An RFID receiver can communicate with an RFID device to determine a position of the RFID device and to initiate a transaction. When the RFID device enters a defined volume, an illuminator can be triggered, which illuminator illuminates the RFID device. Light property data for the RFID device can be collected by a sensor, and the light property data can be compared to light property information for one or several substances. If the light property data matches the light property information, then a substance can be identified as present on the surface of the object.
