A possibility to read an RFID card even on a longer distance is usually highly appreciated at its everyday usage.
As we know, RFID module range is expressively depending on a size and shape of the RFID antenna (coil). That´s why the module with a big antenna has a potentially bigger chance to reach a long range. This is exactly a case of the ID3LA module – working in a wider operating voltages range (2,8-5V) than its predecessor – the ID2 module. This enables its usage even with a 3.3V logic and also for example in battery-operated devices (3-4x NiMH, or 1x Lithium cell, …) not requiring DC converters or a precise voltage regulation.
ID3LA belongs to the „ID3/ID12/ID20“ family with very similar electrical parameters and a way of usage. All modules of this family function as readers sending data – a unique ID of a given RFID tag. The most favourite type – ID12(LA) has a very decent range (approx.. 12cm) sufficient for majority of applications. However, if the space in your application allows you to use ID3LA, you´ll reach a significantly longer range. ID3LA requires an external antenna – included in the package, as illustrated on the attached pictures.
Detailed information will provide you the ID3LA datasheet.
With the ID3LA RFID module it´s possible to read a tag up to 30cm – [Link]
