Can RFID be implemented for forklift trajectory record?

We have one plant which is 300 meters long and 200 meters wide. We need to achieve 30 forklift trajectory record. Can RFID be implemented? How much does it cost?


RFID does not work. Use the electronic fence would be good, with the positioning algorithm.

Electronic fence is something similar to GPS, base on the principle of the station positioning. Those 4 corner is a small base station, through the algorithm positioning.

3-in-1 charge cable 2A or 0.65A?

Is the 2A charge cable with 3 charging sub-cables always be 2 amp in actual usage?

The fact is that 2A is only valid when there is only one smart device is charged.

When 2 device are charged,the current for each is not more than 1A.

When 3 sub-cables are used for 3 smart phones or tablet or game machine,the current for each is 0.65A.

Signal cable
