The KL261 is low sensing array, only have 112 x 88 pixel, when register fingerprint, you have to put multiple time in register fingerprint. If you have high requirements for products and design, we suggest you can chose R503,R502-A serials products, like K202+R503,K215-V1.3+R503,K216 +R503 board and so on.
