How do you know the NFC read distance of the iPhone built-in RFID-NFC reader?Will a small NFC tag give the required distance?How big do you need to have an NFC inlay-tag to get a long read distance? This video uses iPhone 11, the same results will correlate with iPhone 12, and iPhone 13, iPhone 14, iPhone 15, etc. The iPhone built-in RFID-NFC distance between the iPhone and varies based on Inlay/Tag antenna size Round and square antenna shapes are both produce the same correlation: large NFC/antenna/tag size means longer read

Suppose you have LOTS of Bluetooth devices (say 30, 70, 100+) paired to a device. How can this happen? When testing devices during production, this can easily happen. Doing tap gear icon, and tap Unpair hundreds of times, is really not a productive use of time. yACK FAST Android app provides a tool to unpair ALL Bluetooth device pairings in ONE step. Tap SELECT DEVICE, tap upper-right menu, tap “Unpair all devices”. This displays all the currently paired Bluetooth devices on this Android device, with dialog titled “Choose devices to unpair”. By

How do you know what RFID-NFC chip model-type to use for your NFC project? There are hundreds of models, some more popular shown below. What read & write range is needed?What material will RFID-NFC tag be applied to, or inserted in?How much data needs to be stored?What read & write speed is required? Read range is often an important parameter in choosing type of RFID-NFC chip. Video below shows the read range of NTAG213 vs SLIX2 chips in tiny rigid PCB NFC tags (4.8mm square, 1.8mm thick).This type of tag is available in

A food production facility on the east coast was on the hunt for a solution for their production line.When dealing with food products, they needed to be sure that weights were properly recorded and within reasonable limits in order to proceed. Once the software was in place, the next important step was getting the right hardware.  Manual entry is cumbersome and prone to human error. When a significant portion of the day is spent recording weights, a mistake being made doesn’t just eat up time–it costs money. With, of course,

How To Use Standard NFC Sticker Tag On Metal Surface Standard NFC tags fail to read when you put them on a metal surfaces. Here we show how you use NFC Sticker Tag On Metal Surfaces.A typical RFID-NFC tag or inlay you use, will read with any NFC reader when placed on non-metallic surfaces. You put the tag on stone, wood, glass, plastic, paper, or hold it in the air, and it works fine. Why Do RFID-NFC Tags Not Work On Metal? Here is a typical round 8mm adhesive sticker

Wireless RS-232 Scale With Your Current Scale You connect your RS-232 scale with BlueSnap M6A, now you have a Wireless RS-232 Scale On MacOS. First you get the optional HID wireless keyboard firmware option for the BlueSnap M6A. Next you post weight readings as keystrokes to all MacOS apps that allow typed input, without special software. Third, the BlueSnap M6A serial dongle connects wirelessly eliminating cables between your scale and Mac. Finally you transmit data up to 30 feet (10 meters) between scale and Mac giving you great portability. No
