The primary difference between active and passive tags is that active tags have their own power source (typically an embedded battery) and passive tags rely on the RFID reader's propagation signal to power the tag.
An RFID tag consists of a tiny radio transponder; a radio receiver and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to inventory goods.
The easiest way to test the RFID blocking of your wallet, cardholder, or other device is to head to a pay point that lets you scan your card instead of swiping. You're looking for a PayPass terminal in the US. Simply scan your wallet with your card in, perhaps asking for permission to try it first.
The first disadvantage to using RFID software is cost; with a bar code, you can produce one for around one penny. At the moment, an RFID tag will cost you more than 12p a piece at the least. ... Another disadvantage of using them deals with their programming speed, which takes a lot more time than setting up a barcode.
Check whether the power supply voltage is insufficient, the voltage is unstable, and whether the iron sheet magnetism is sufficient.
Whether the magnet piece is aligned with the lock body, check if the lock body is energized.
Electronic locks are locked or unlocked with the assistance of an electrical current. The electrical current is either used to power an electromagnet, a solenoid (electromagnet with a single coil), or a motor. These devices will actuate the lock in a manner that is either fail-safe or fail-secure.
Whether the iron sheet is aligned with the lock body, the lock body is not magnetic, and the lock body is broken.
The lock body is heating up. Check whether the power supply voltage is too large, whether the wire is short-circuited and the contact is poor, or the lock body itself is quality.
