How to Evaluate Merchant Services for Your Business

May 30, 2016 by · Leave a Comment 

online-merchant-accountWhen you’re shopping online or offline for a merchant service provider, you’ll quickly realize there are a lot of options. Choosing the right one amongst all those names can feel daunting, unless you create system for yourself to help evaluate each provider based on your needs. With this guide, you’ll be on your way to figuring out what those needs are so you can figure out a baseline to evaluate the companies you come across.

Customer Service

The first thing you need is a good support system to help you when things go wrong. Call the payment processing company you’re looking to work with and ask them a few basic questions. You might want to ask about:

  • Monthly or yearly fees. If fees exist, ask to have them waived.
  • Setup fees, and what hardware or software you can expect to receive in exchange.
  • Rates and pricing structures.
  • Amex fees.

Anything that feels relevant to your business is on the table, so be sure to prepare questions beforehand. For example, you might want to inquire about whether services will work as an internet merchant account and an in store POS.

Research

What registers are best for stores? Which payment processors work with iPads, Androids and other mobile devices? What about chip readers? Do some cursory research in this market to see what’s in for the foreseeable future. This will save you money later in the lifespan of your business, because you won’t need an upgrade for several years.

Final Thoughts

Once you understand more about the customer service, pricing and contract terms you know basically everything you need to know to evaluate a provider. You might want to keep some specific concerns in mind, but you should have enough knowledge to get the process started.

The Combinatorial Libraries of Oligonucleotides

To distinguish one member from another in the pool of oligos, a tagging system has been created.

dna-croppedOver the last ten years, there has been significant improvement in the development of compound libraries for the discovery of molecules with new binding properties. The basic premise is to ultimately shorten the effort and time associated with the search of drugs leads by creating a large combination of molecules that are tested against a certain target for a specified activity. However, there is a problem with this technique as that there lacks a proper strategy to determine the identity of the active molecules from the mess of the original pool. To solve this, researchers have developed a system that utilizes either tagged or untagged labels.

Tagging Methodology

The use of these tags have established a beneficial relationship between each single member of the library and the tags itself with gives it a unique identity. Even through the process of synthetic DNA playing a role in presenting itself as a different member, these powerful tag technologies have become important tools to separate themselves from the pack. Additionally, researchers have discovered flexible and versatile ways to apply these tags to multiple areas of molecular biology, therefore expanding the real of possibility.

SELEX

There is a certain strategy that makes use of modified oligos that’s called Selective Enhancement of Ligands by Exponential Enrichment, or SELEX for short. What this technique does is executes multiple cycles of selection and amplification, which results in competition between the molecules that are deemed suitable from the huge population in the pool. Essentially, the pool is separated by individual members to appropriate them to a given task (usually a binding or catalytic task).

PVD Coating vs. Gold Plating

Both techniques have their own unique advantages to them that offer the user numerous benefits.

gold-barsIn the jewelry business, there are several different processes and techniques used to achieve a gold look. Now, aside from the fake products, two of the more common ways to achieve this appearance are through gold PVD coating and gold plating. Sure, they sound like they’re essentially the same process, but each has their own unique advantages that adapt to certain situations. So, what differentiates the two from each other?

PVD Coating

Physical vapor deposition, otherwise known as PVD, is a process that occurs within vacuum deposition systems that produce a decorative and functionally beautiful finish. PVD typically utilizes titanium nitride to provide a tough, durable coating layer on top of a substrate. PVD coatings tend to be more resistant to corrosion, moisture, and the other wear and tear features that watch users undergo.

Gold Plating

Gold plating, on the other hand, occurs when a piece of real gold is plated onto another type of metal – say, stainless steel for example. This process is often done as a cost-efficient way to achieve the look of real good. One advantage that gold plating has is that it gives the product the look of actual gold. It’s aesthetically pleasing to the eye and can be used on a variety of products. And, without having to pay thousands more to obtain a thin film vacuum coating, you can save a substantial amount of money. However, gold plating doesn’t have the same durability and resistance that PVD coating offers, leaving its security at the whim of the user.
