The articles tell you programming RFID tags in 5 minutes.
RFID is short for “Radio Frequency Identification”. RFID Tag also known as proximity cards, contactless cards, and electronic tags.
Most RFID systems are made up of the same components. Basically can be divided into: readers, antennas, electronic tags.
And programming RFID tags, you only need an electronic tag and a handheld reader.

Basic read and write operations:
programming RFID tags often does not require professional equipment. A mobile phone with NFC function is also available, just download an app with your mobile phone – “NFC info”
When the electronic tag is close to the phone, it can be read.
TYPE A (ISO/IEC 14443 TYPE A)
This is the current protocol for electronic tags. In fact, this protocol also clarifies the frequency of electronic tags.
PS: ISO 14443 TYPE A has been determined that the electronic tag is a high frequency electronic tag, 13.56 MHz
We can see that the word “SMART CARD” is on the map.
Yes, this time I read a smart card. It is worth noting that many smart cards, such as bus cards, card, access card, and campus card, are all ISO 14443 TYPE A protocols. They are technically versatile.
What else can I do?
Click on “Tag information…”
This is the detailed information inside this electronic tag.
If a professional reader/writer works with a specific software, there will be more, and the current information is more organized and easier to understand.
So what can be achieved is:
Find the EPC number of the RFID tag, which is the electronic product code.
If the read electronic product code is 00000000000000000000001, then we can change it to: 0000000000000000000000002.
The implementation of the software can give electronic tags, establish names and store other information.
It is worth noting that other electronic tags should not be placed next to the information entered into the electronic tag to avoid interference with the normal operation of the entry.
The Internet of Things is a big trend from outside. The role of electronic tags is to give each person a tangible object. With this “core”, this object has other meanings for the outside world. Let others know about its past and present and know its past future. The Internet of Things and electronic tags are not so mysterious. If you have a mobile phone and the mobile phone has NFC function, you can also try it and feel the charm of the Internet of Things.
