1st Practical Lesson!!!
After so many week of waiting, finally had our very 1st Practical Lesson.On the lesson we get contact with what we call the UHF (Ultra High Frequency)and HF (High Frequency)reader.And found out that RFID is weak in metal and water.It was amzaing, as I thought that RFID should be strong in that, but it wasn't as what i had thought
Benifit
RFID had to technology to send very huge amount of data as the product travel through the supply chain and it can be updated throught out every step of the manufacturing product, due to this it can lower the error and vendors can save alot.
Advantages
There is alot of advantages in RFID,firstly many item could be scanned just by passing through,within each tag there will be hidden data source and this can be portable anywhere.Other than that in Passive tag it had unlimited virtually lifetime and in Active tag it could be read in long distance.The data inside the tag could be modified through the lifetime.In every tag it is unique as the ID is only for the Tag
Disadvantages
If there is advantages there is also disadvantages.Its advantages is also it disadvantages.As item could be scanned just by passing throught,some item which are not wanted is also being scanned through which might cause some inconvenience.Other than that,every tag is costly and there is limitation in reading and writing for passive tag.There is currently lack of standard.
