In vitro sensitivity of commercial scanners to microchips of various frequencies

To evaluate sensitivity of 4 commercially available microchip scanners used to detect or read encrypted and unencrypted 125-, 128-, and 134.2-kHz microchips under controlled conditions.Evaluation study.Microchip scanners from 4 manufacturers and 6 brands of microchips (10 microchips/brand).Each microchip was scanned 72 times with each scanner passed parallel to the long axis of the microchip and 72 times with each scanner passed perpendicular to...
