LEDs were installed into the sockets of the NFC wand. They were ordered from a different fabrication house and they were a tighter fit than those from EasyEDA. This was not a problem, just an observation. Once connected, the RFIDWand was held near an NFC field but there was no light. On closer inspection, the traces were not intact under the solder mask. This was a manufacturing issue and only occurred on a single board. Another board was populated and continuity was tested and found to be good. When exposed to another NFC antenna, there was still no light.
The NFCField card was tested for continuity and populated with an LED. This card used the same antenna as the NFCWand. The results were the same, unfortunately. This antenna did not appear to be successful.
The DynamoCard, which was intended to use a shaken magnet to generated power was populated with an LED and two axially magnetized neodymium disks were attached by their own attraction. When shaken, there was no observably generated power.
As a test, the DynamoCard was held near an NFC field. The light turned on but the magnet was immobile. This suggested that the length of the NFC antenna in the NFCField and NFCWand was too short and that the number of turns is to low for the DynamoCard. These were valuable lessons and cheaply learned.
