Here is some more backup information including digital wallets from another company: Tapping to make a purchase isn’t all about making your life simpler, it also creates a more secure way to shop. By using a combination of chip technology, Near Field Communication (NFC), and Radio Frequency Identification (RFID), contactless cards are safer than your traditional swipe or insertion of a credit or debit card. This is because each transaction uses a one-time, unique digital code to facilitate secure communication between your card and the card reader. This dynamic authentication process significantly reduces the risk of card fraud and unauthorized access to your financial information. By embracing contactless payments, you can enjoy peace of mind knowing that your transactions are protected by advanced security measures. Because there is limited physical contact with payment terminals and cashiers, there is a reduced risk of skimming devices or malicious software stealing your card information. By minimizing physical interaction, tap to pay helps protect against card cloning, counterfeit fraud, and other forms of tampering. In the event that your mobile device or digital wallet is lost or stolen, many digital wallets offer additional security such as biometric authentication (fingerprint or facial recognition) or a unique PIN to ensure that only authorized users can access your payment information.

This past year, many CC companies have implemented new processes for RFID or contactless CCs. Many cards have been replaced a year or more before their expiry date. AMX bumped us into new cards 2 years before the expiry date. They no longer transmit the CC account number. Instead a transaction number is transmitted. It is only good for that one transaction. I looked for the info I had a few months ago but can't find it now. They are pretty quiet about its details. One CC company describes their process as: Chip technology. Your Credit Card’s chip is essentially an updated, more secure alternative to the magnetic strip on the back of the card. For each transaction, your chip creates a one-time-use encrypted code that’s used to instantly verify your account information. Because a new code is created every time you dip your card, it makes it impossible for a fraudster to make a counterfeit of your card. The stories about someone lifting your CC account number while you are walking down the street will disappear with this change. It has been implemented in Europe before USA and Canada finally started to adopt it. So has had a good run of testing. Hope it continues to be safer.

Have you tried searching here on LW ? I think I have seen some posts about the mystery braid. If the search engine here doesn't find much, try doing a google search like this: site:leatherworker.net mystery braid The site parameter forces google to search the site listed. Change the search parameters (mystery braid) as needed. Here is one that popped up with the above search.

Please post your photos here. 3rd party hosted photos frequently disappear due to changes in the host's policies, host out of business, users moving files, deleting files, closing their account or the account expiring. When this happens, the post becomes worthless to all future users who are researching or looking for help to solve a problem. If your files are too large to post here due to file size restrictions, you need to resize your files to fit. Follow this link for some helps and suggestions. https://leatherworker.net/forum/topic/15122-how-to-post-pictures-on-lw/?do=findComment&comment=551171 There are lots of Apps, software, and online tools available on the web, or even built into your device to enable you to reduce your file sizes. 800 pixels in the longest dimension is quite adequate. Smart phone screens and many monitors don't display high res files in high resolution. People that live on the fringes of the internet appreciate smaller file sizes and high res photos may take from 10 minutes to hours to download.

Don't do back-stitching on your machine. Leave extra long tails at the start and finish, then manually back-stitch (saddle stitch) using harness needles. You can then place your stitch more accurately, and relatively no risk of damaging the threads.

If you are looking for info on magnets, check out this link. They have lots of types and supporting information. For a stitching pony with magnetic jaws, you may need a strong magnet separator. Lots of experiments under their blog page. Lots of rabbit holes!

It is the reaction between iron and tannin, same as used to make vinegaroon if you would like to look that up. Keep all iron filings off your work space! You may be able to bleach it out using oxalic acid (teaspoon full in a pint of water) or wood bleach, or barkeeps friend (which all contain oxalic acid. Rinse after to reduce the acid left in the leather.
